Public Comment No. 15-NFPA 13D-2017 [ Section No. 7.4.5 ]

7.4.5*

Where sprinkler piping is exposed to the sprinkler protected area, it shall be supported with metal hangersor hangers listed for this application. made of the same material as the structure.

Annex note submitted as separate PC

A.7.4.5

Wood used as part of a trapeze hanger is considered an extension of the structure and is considered acceptable to

hang sprinkler piping.


This proposal will clarify misconceptions about hanging pipe from a wooden structure. AHJ's have been disallowing this as they consider a wood trapeze to be a nonmetallic hanger.

This language will also address the concerns of the correlating committee (see CN-1)Annex note submitted as separate PCA.7.4.5Wood used as part of a trapeze hanger is considered an extension of the structure and is considered acceptable to hang sprinkler piping.

Public Comment No. 22-NFPA 13D-2017 [ Section No. 8.1.3.1.2 ]

8.1.3.1.2*

Where construction features or other special conditions exist that are outside the scope of sprinkler listings,listed sprinklers shall be permitted to be installed beyond their listing limitations.

A.8.1.3.1.2. Technical documentation should be provided to the authority having jurisdiction thatdemonstraits that the modification is in compliance with the intent and purpose of this code and that suchmodification does not lessen health, life and fire safety requirements.


The purpose of this comment is to state that an approved report should be provided prior to installing fire sprinklers outside of their listing. The base code allows for the installation of fire sprinklers outside of their listing, but does not provide SUFFICIENT guidance on the limitations of this provision. Requiring the report will provide guidance on acceptable methods of installation, even if outside of the listing of the fire sprinkler.

Public Comment No. 23-NFPA 13D-2017 [ Section No. 8.3.4 ]

8.3.4*

Sprinklers shall not be required in garages, open attached porches, carports, and similar structures.

8.3.4.1 Attached garages with any habitable rooms above shall be required to be protected withfire sprinklers.


A fire in a garage without fire sprinklers with habitable rooms above it can undermine the structural integrity of the habitable rooms above and increase the risk of occupants within those rooms not being able to exit the structure safely.

The committees comment, "Building code requires separation. The passive protection (1 Hour) provides more time than the 10 minute limit of the FSS".

The building code passive protection is not actually 1-hour and in many situations is not even 10 minutes.

The water supply is normally in the garage. Adding sprinkler protection into the garage is easy to do.

A.6.2


16 of 24 5/16/17, 12:47 PM

The connection to city mains for fire protection is often subject to local regulation of metering and backflowprevention requirements. Preferred and acceptable water supply arrangements are shown in FigureA.6.2(a) through Figure A.6.2(e). Where it is necessary to use a meter between the city water main andthe sprinkler system supply, an acceptable arrangement as shown in Figure A.6.2(c) and Figure A.6.2(d)can be used. Under these circumstances, the flow characteristics of the meter are to be included in thehydraulic calculation of the system [see Table 10.4.4(a)]. Where a tank is used for both domestic and fireprotection purposes, a low water alarm that actuates when the water level falls below 110 percent of theminimum quantity specified in 6.1.2 should be provided.

The effect of pressure-reducing valves on the system should be considered in the hydraulic calculationprocedures.

Figure A.6.2(a), Figure A.6.2(c), or Figure A.6.2(d) are acceptable methods for getting the water supplyinto the unit for a stand-alone sprinkler system (one that does not also provide direct connections to thecold water fixtures) because the common supply pipe for the domestic system and the sprinkler systembetween the water supply and the dwelling unit has a single control valve that shuts the sprinkler system,which helps to ensure that people who have running water to their domestic fixtures also have fireprotection. This serves as a form of supervision for the control valve and can be used to make sure thatthe valve stays open in place of other, more expensive options such as tamper switches with a monitoringservice.

Some water utilities insist on separate taps and supply pipes from the water supply to the dwelling unit forfire sprinkler systems as shown in Figure A.6.2(d), due to concerns about shutting off the water supply fornonpayment of bills and the desire not to shut off fire protection if this ever occurs. While these types ofarrangements are acceptable, they might not be cost efficient and should be discouraged due to the extracost burden this places on the building owner. It is extremely rare that the water utilities would actually shutoff water for nonpayment, and even if they do they are creating a situation in which the dwelling would beunfit for occupation.

Annex C Press-Connect Fittings used in Fire Sprinkler Applications

(See separate document for proposed text of Annex)



NFPA_13D_Public_Comment_Annex_Information_Press_Connect_Viega_Submitted.docx

NFPA 13D Public Comment Proposed Annex C


Currently there is no definition for Press-Connect fittings in NFPA 13D. The term Press-Connect Fitting is used in both the IAPMO and ICC codes. The wide use of Mechanical type fittings has created the need to identify fittings such as Press-Connect and provide definitions to prevent confusion between mechanical fitting types and to help identify the correct standards these fittings are typically listed to. The proposed annex provides reference information which will be helpful in distinguishing between Mechanical type fittings and Press-Connect Fittings.

In the first draft review meetings our public comments 32, 33, 88, and 89 were resolved because all press-connect systems require listings and thus are not to be listed in the existing tables for standards whose products do not require separate listings.

It was suggested by a few committee members that information on Press-Connect fittings be added instead to the Annex of this code for reference and informational purposes.

Proposed New Annex

Annex C Press‐Connect Fittings used in Fire Sprinkler Applications This annex is not a part of the requirements of this NFPA document but is included for informational purposes only.

This annex is intended to provide basic information and description of press‐connect fittings for metallic

piping systems used in fire sprinkler systems. All press‐connect fitting systems used in fire sprinkler

applications require listing(s) specific to the application. Because press‐connect fittings are not

specifically included in the mandatory sections of this standard the following information will discuss the

press‐connect fitting connection in more detail.

C.1 Definition of Press‐Connect Fittings

The press‐connect fitting is a permanent mechanical connection for joining copper tubing or steel pipe

typically utilizing an elastomeric seal or an elastomeric seal in conjunction with a corrosion resistant

axial biting or grip ring or rings. Fitting connections are generally pressed with an electro‐hydraulic

pressing tool utilizing pressing jaws or pressing rings approved by the fitting manufacturer for use in

accordance with their listing.

C.2 Applications of Press Connect Fittings

Press‐connect fittings are commonly used today in both dry (pre‐action) systems as well as wet systems.

Press‐connect system designs must not exceed the maximum pressure and ambient exposure

temperature ratings for fittings and piping. The maximum continuous exposure temperature is limited

by the elastomeric sealing element material. A manufacturers’ listing will specify the maximum

continuous exposure temperatures for their press‐connect system.

C.3 Standards for Press‐Connect Fittings

Press‐connect systems are generally manufactured in accordance with ASME B16.51, Copper and

Copper Alloy Press‐Connect Pressure Fittings; or IAPMO PS‐117, Press and Nail Connections; or ASTM

F3226/F326M, Standard Specification for Metallic Press‐Connect Fittings for Piping and Tubing Systems

depending on the type of piping. These standards specify the material requirements and the

performance criteria such as, but not limited to, Hydrostatic Pressure Test, Static Torque Test, Bending

Test, Vacuum Test, Pressure Cycle Test, Vibration Test, Thermocycling Test, and Dynamic Torque Test.

C.4 General Assembly Procedure for Press‐Connect Fittings

Press‐connect fittings all have an elastomeric seal that forms the seal‐tight joint. The pipe or tubing is

cut square, deburred and chamfered and, or reamed to restore the full inside diameter. The ends of the

pipe or tube that will be inserted into the fittings should be carefully inspected for any noticeable

damage or deep scratches and also checked and cleaned if any foreign matter such as dirt or tape

residue is present. The pipe or tubing is then fully inserted into the fitting until the internal shoulder

stop is reached and the tubing is then marked with a permanent marker where the tubing meets the

outer shoulder of the fitting in order to establish the full insertion depth. With the tubing fully inserted

54

and the insertion depth mark double checked, the joint can be pressed using the tool recommended by

the manufacturer. The insertion depth mark should be checked once again after pressing to insure the

joint did not slip apart during the pressing operation. Pressure testing of completed sections should

then be conducted per the manufacturer’s instructions and this code to insure all joints are seal tight.

Public Comment No. 56-NFPA 13R-2017 [ Section No. 5.1.3 ]

5.1.3 Rated Pressure.

System components shall be rated for the maximum system working pressure to which they are exposedbut shall not be rated at less than 175 psi (12.1 bar) for components installed above ground and 150 psi(10.4 bar) for components installed underground between the water supply and the system riser. When theunderground piping can be supplied or pressurized by a Fire Department Connection (FDC), theunderground piping shall be designed to withstand a working pressure of not less than 200 psi (Class 200),or 50 psi greater than the system design pressure, whichever is greater.


This Comment/PI intends to require higher pressure ratings for underground lines that can be fed by Fire Department Connections. Delivery of water at Fire Department Connections can cause pressures that exceed 150 psi. Typically, use of 200 psi rated line can withstand the pressures delivered at the FDC. However, when higher pressures are required at the FDC due to system demands, the underground line is required to be listed for 50 psi above that demand pressure. The 50 psi above design pressure is to allow for pipe to be listed for the pressure used during the hydrostatic test.

The FDC has been used as the only source of water for the system when the main water source is out of service.

This public comment is a slight revision of Public Input No. 86 eliminating the specified means of limiting pressure (thereby eliminating the committee's concern of an "additional failure point". This concept is also being resubmitted based on the committee statement for Public Input No. 93, which states "If excessive pressures are introduced to the system through the FDC, such pressures are for a limited time and are flowing pressure (fire event). Pipe can handle pressures in excess of their rating for limited time."

Public Comment No. 28-NFPA 13R-2017 [ Section No. 5.2.2.3 ]

5.2.2.3

Pipe or tube listed for light-hazard occupancies shall be permitted to be installed in concealed spacesabove ordinary-hazard rooms.


When nonmetallic pipe and tube first got listed for use in fire sprinkler systems, there was a requirement to separate the pipe and tube from the protected light hazard space using some sort of construction material (typically wood, gypsum board, or plywood). This effectively created a concealed space above the protected light hazard space that contained the pipe. No new information has come forward to show that the pipe would be able to withstand the increased heat release from an ordinary hazard fire in the same type of concealed space. There is no information on what minimum construction should be used to separate the concealed space from the ordinary hazard area and there is no information on how to seal any potential penetrations or openings to the concealed space (remember that concealed spaces are permitted to have small openings such as the return air openings in a plenum). There is no evidence that nonmetallic pipe or tube subjected to a fire likely to come from an ordinary hazard space will survive prior to sprinkler operation. And if the pipe does not survive, how will water get to the sprinkler?

5.4.2* Systems in Areas Subject to Freezing.

Where any portion of a system is subject to freezing and the temperature cannot be maintained reliably ator above 40°F (4°C), the pipe shall be protected by use of one of the following methods:

(1)

(2) Dry pipe system

(3) Preaction system

(4) Listed dry pendent, dry upright, or dry sidewall sprinklers extended from pipe in heated areas

(5) Heat tracing in accordance with 6.7.2.2

(6) Heat tracing in accordance with 6.7.2.2


APPA disagrees with adding a trust heat trace to prevent freezing. It has a habit of failing regularly and without warning. We agree with Technical Committee member Peter T. Schwab’s Affirmative Comment, “The committee statement would make excellent annex language because it indicates that the temperature of the space that the wet pipe is installed can get below 40 degrees as long as the pipe does not freeze.” We are asking the technical committee to review this subsection to ensure it is enforceable.

(1) Lobbies not in hotels and motels

(2) Foyers

(3) Corridors

(4) Halls

(5) Lounges

(6) Ordinary-hazard areas in accordance with 7.2.4.1

(7) Garages in accordance in accordance with 7.3.4 and 7.3.4.1(1)

(8) Porches, balconies, lanais and similar areas

(9) Other areas with fire loads similar to residential fire loads


Some AHJ's consider these areas "outside" the dwelling unit since they are exterior. Residential sprinklers should be allowed when these areas are required to be protected (Type 5 construction).

6.5.5* Temporary Protection During Construction, Alteration or Demolition.

Temporary fire sprinkler protection during construction, alteration or demolition shall comply with NFPA241.

A.6.5.5 During construction, alternation and demolition, there are many hazardous conditions, such ascutting, welding, grinding and combustible or hazardous product storage that can be made safer byinstalling a temporary fire sprinkler system. Given that such protection will be supplemental to any otherprotection that would be required, NFPA 241 permits temporary fire sprinkler protection when approved bythe AHJ.


In discussing rejection of PI 107, the committee suggested that the issue of temporary sprinklers during construction was better suited for inclusion in NFPA 241. That suggestion was pursued and resulted in an addition of a new section on temporary sprinkler protection in the next edition of NFPA 241. It is appropriate for NFPA 13R to include a reference to NFPA 241 since sprinkler contractors won't ordinarily be familiar with that standard.

For reference, the NFPA 241 text is as follows:

7.9 Temporary Protection During Construction, Alteration or Demolition.During construction, alteration or demolition, the use of temporary fire sprinkler protection approved by the AHJ shall be permitted as supplemental protection.

A.7.9 During construction, alternation and demolition, there are many hazardous conditions, such as cutting, welding, grinding and combustible or hazardous product storage that can be made safer by installing a temporary fire sprinkler system. Given that such protection will besupplemental to any other protection that would be required, there is no harm in allowing this additional safety feature on a temporary basis if the design basis and installation is considered acceptable by the AHJ.

Storage beneath the open tread stairs is unlikely and discharge from surrounding sprinklers will address the fire if one were to occur there. Without guidance the industry tends to refer to NFPA 13 which is extremely conservative.

6.6.10 Open-Ended Corridors.

ramps where the corridor and stairway is not separated.

6.6.10.2 Exterior corridors that are 50 percent open shall not be required to be protected.

A.6.6.10.2 An example of an exterior corridor that is fifty percent open is shown in Figure A.6.6.10.2.


Reconsider PI #27 and insert the suggested language from PI #27. The title of section 6.6 is "Location of Sprinklers" so it appears to be warranted that one would go to chapter 6 to look to see how open corridors are addressed with respect to fire sprinkler protection under NFPA 13R. By not addressing this issue, the TC creates the potential for this item to be missed by the contractor and AHJ at the time of permit, then only to be caught at the time of inspection. This approach only encourages confusion and the potential for change orders that serves no one. The installation standard should strive to provide clarity and direction as to when and where fire sprinklers are required. PI #27 accomplishes that objective with no downside. The TC should reconsider the text as proposed in PI #27.

Public Comment No. 2-NFPA 13R-2017 [ New Section after 6.8.8 ]

6.8.9 Multiple Occupancies

Control valve arrangements in mixed occupancy buildings with a residential occupancy shall be in

accordance with 6.8.9.

6.8.9.1

In podium/pedestal buildings, the system(s) below the podium/pedestal shall have a separate control valve.

6.8.9.2*

In buildings that are not a podium/pedestal where there are mixed occupancy/occupancies and NFPA 13 is

used for the non-residential occupancy/occupancies, a single control valve shall be permitted for the entire

building.

A.6.8.9.2

NFPA 13 requires a separate sprinkler system per floor in multi-story buildings meeting certain

requirements. It should not be necessary to follow these rules where there are mixed occupancies and the

use of NFPA 13 & NFPA 13R systems.

6.8.9.3*

In buildings with mixed occupancies and the non-residential occupancy is mercantile, it shall have a

separate control valve.

A.8.9.3

Many mercantile spaces require modifications as tenants move in and out. The addition control requirement

is to prevent the residential portion from being shut down during modifications.


Reconsider PI #57 and accept the proposed text from PI #57. The concerns raised in PI #57 are valid and should be addressed. As an example, in a mixed occupancy building with residential above mercantile, business or assembly, there will be many occasions where tenant improvement work is occurring in the non-residential occupancies. Without separate control valves, the residential portion of the building will be without fire sprinkler protection while the TI work is occurring in the non-residential spaces. This creates an unnecessary hazard within the residential occupancies when they are without protection due to the TI work.

In addition, with the TC justifying a resolution on this issue by stating there are certain situations when a single control valve would be acceptable, that then raises the inverse of the resolution statement....If the TC feels there is justification for "certain situations" where a single control valve would be acceptable, that also means there are also "certain situations" where a single control valve is clearly not acceptable. If there are truly "certain situations" where the single control valve is warranted, TC could address this concern in the PI resolution by revising the PI language to address the specific situation where the TC is envisioning a single control valve being acceptable by simply including such language in the standard under this section. (The proponent of this PC is not proposing such language and he is unable to envision a "certain situation" where single control valve would be acceptable.)

Attics that are intended for occupancy or storage shall comply with Section 7.1 , where the attic is part ofthe dwelling unit, or Section 7.2 , where the attic is outside of the dwelling unit. NFPA 13.


An attic would most likely never be acceptable for living purposes per model building codes. See the definition below from the ICC and the commentary in regards to attics. An attic used for storage accessible from the dwelling unit or outside the dwelling unit needs to be protected in accordance with NFPA 13. Also recommend changing the title.

OCCUPIABLE SPACE. A room or enclosed spacedesigned for human occupancy in which individuals congregatefor amusement, educational or similar purposes or inwhich occupants are engaged at labor, and which is equippedwith means of egress and light and ventilation facilities meetingthe requirements of this code.

Occupiable spaces are those areas designed forhuman occupancy. It applies to both residential andnonresidential spaces alike. Most spaces in a buildingare occupiable spaces. Based on the nature ofthe occupancy, various code sections apply. All habitablespaces are also considered occupiable (see thedefinition of “Habitable space”). However, all occupiablespaces are not habitable. Additionally, somespaces are neither habitable nor occupiable. Thecode identifies crawl spaces, attics, penthouses andelevated platforms (mechanical or industrial equipment)as unoccupied spaces. Since the code generallystates how these spaces must be accessed, butdoes not specifically require means of egress, theywould not be occupiable spaces. If access is limitedto maintenance and service personnel, it is likely thata space is not occupiable.

This correlates with new section 6.11.6 that allows a common FDC in buildings with mixed use and NFPA 13 and 13R criteria in the same building. If the FDC is common and the fire fighters will be using hose streams during a fire event, the water supply must be capable of supplying the system demand plus the hose streams.

These tables are old and do not reflect the newer low flow technology of plumbing fixtures. It is one thing to have them in the annex as suggestions. It is another thing to have them in the body of the standard, making them mandatory. If the committee wants mandatory values for combined domestic demand, the values need to be more representative of current fixtures.

(Delete these sections on the domestic demand and their Tables from the body of the Code. Notethat the Annex Note to Section 9.3 still has these two Tables listed and shown in the Annex Notewhere they should be based on my Committee notes I took during the First Draft Meeting.)


I distinctly remember at the First Draft Meeting we had discussion about moving the old Fixture Load Values (Table A.9.6(a)) and Total Estimated Domestic Demand (Table A.9.6(b)) from the Annex to the body of the Code under this FR. We discussed that these Tables were from more than 30 years ago and that the recent Model Plumbing Codes have revised similar Tables in their Codes to reflect modern, more energy and water saving efficient fixture loads and water demands. The Committee agreed that moving these Tables at this time into the body of the Code was not a good move and voted not to move them from the Annex. We voted on deleting the proposed new Section 9.3.2 from this rewrite of Chapter 9 and it passed. However on the ballot this Section is shown as being part of the First Revision. To confirm my understanding that the Committee did indeed agree to leave these Tables in the Annex, Staff did place these Tables in the Annex Note to New Section 9.3 but forgot to delete these two Sections from the body of the Code. So since the Tables are shown in the Annex Note for Section 9.3, I conclude that my notes were correct and it was the intent of the Committee to leave the Tables in the Annex. To further the argument to leave these Tables in the Annex is the fact that both these Tables are only in the Appendix of each of the Model Plumbing Codes (IPC and UPC), not in their body of the Code. It would be poor code practice to place Appendix Items from the plumbing codes into the body of the NFPA 13R Standard. Also, it is my understanding that the Model Plumbing Codes are reviewing code proposals based on research and a study that was conducted at the University of Cincinnati that is a new method for sizing the water piping based on flow rate and probability of simultaneous use.The sizing method uses Hunter's concepts and updates the sizing based on a study conducted throughout the US (See http://tinyurl.com/kxcevr7 for detailed information on this new method). To lock users of NFPA 13R into only one method to calculate domestic demand based on old technology would not be in the best interest of the fire protection and plumbing communities. We should leave these Tables in the NFPA 13R Annex so the code user can continue to rely on the Model Plumbing Codes to address the domestic water demand options in our modern buildings.

6 Where a waterflow test was conducted to determine the strength of a water supply and knowledge ofthe water supply is available, the volume and pressure available for use for a fire protection system shallbe determined from 9.3.6.1. Where a waterflow test was conducted to determine the strength of a watersupply and knowledge of the water supply is not available, the volume and pressure available for use fora fire protection system shall be determined from 9.3.6.2.

9.3.6.1* Water supply adjustments shall be based on knowledge of the water supply and engineeringjudgment taking into account reasonable daily and seasonal fluctuations not extreme conditions.

9.3.6.2* If knowledge of the water supply is unavailable, the following formula shall be used to determineavailable flow and pressure:

P = The pressure available from the water supply to use for a fire protection system that will becalculated for a given flow (Q)

Q = The flow that will be used to calculate the available pressure from the water supply.

P R = The residual pressure measured during the waterflow test while the flow Q R was

discharging from the water supply.

P S = The static pressure measured during the waterflow test.

Q R = The flow discharging from the water supply when P R was measured.

P L = The expected low static pressure at the location of the test results accounting for daily and

seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the waterauthority does not provide P L , see 9.3.6.3.

9.3.6.3 Where the water authority does not provide a value for P L , the value of P L shall be calculated

from the following formula:

P L = 0.9P S

A.9.3.6.1 The purpose of the adjustment is to take into account reasonable daily and seasonal variationsin the water supply, which are easily predicted and tracked by a water utility. It is not the intent to use thissection to account for unusual conditions such as 100 year droughts or water main breaks. Theseunusual conditions are handled through the Impairment Procedures of NFPA 25 and should not beconsidered when determining the ability of a water supply to meet the demand of a fire protection systemunder more normal circumstances.

A.9.3.6.2 Consider the following example. A waterflow test is conducted at a location where a city watermain is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearbyhydrant. The water utility is contacted and they indicate that a reasonable low static pressure accountingfor typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the watersupply available for a fire sprinkler system would be:

There are two ways to use this formula. One would be to assume two different values for Q, calculate Pand then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the lineon this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In thiscase, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in FigureA.9.3.6.2.

The second way to use this formula would be to calculate the fire protection system and determine theflow necessary to make the system work. Plug this flow into the formula above and see what theavailable pressure from the water supply will be at that flow. For example, if a sprinkler system connectedto this water supply had a demand of 580 gpm, the available pressure from the water supply would be:

the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances. A.9.3.6.2 Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant. The water utility is contacted and they indicate that a reasonable low static pressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the water supply available for a fire sprinkler system would be:

QP

There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in Figure A.9.3.6.2. The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be:

551300

P

P = (-20)(0.225) + 55

P = 50.5 psi

So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply.

Public Comment No. 29-NFPA 13R-2017 [ Section No. 9.7 ]

9.7 Fire Pump.

9.7.1* A single automatically controlled fire pump in accordance with NFPA 20 shall be an acceptablewater supply source.

9.7.2 Fire pumps shall be designed and installed in accordance with NFPA 20.

A.9.7.1 A separate fire pump is not required for every building. It is a common and acceptable practice toprovide a single fire pump for multiple buildings where the buildings are under the control of the sameowner or management firm, or where the multiple owners of the buildings have enterred into a cooperativeagreement for the maintenance and care of the fire pump system. In the case where a fire pump servesmultiple buildings, it must be sized so that it can meet the demand of the largest single fire that might occurin any of the buildings, but it is not required to meet the demand of multiple fires simultaneously.


There are two separate and distinct ideas being provided in section 9.7. It is better to separate them so that there is no confusion. If section 9.7 is left as it was in the first draft, it implies that a fire pump that does not meet NFPA 20 might be acceptable, which has not been the position of the committee. Also, clarification of the single fire pump for multiple buildings is important to the concept of having a single fire pump as proposed in the first draft.

NFPA 13R is appropriate for use as an alternative to NFPA 13 only in those residential occupancies, asdefined in this standard, up to and including four aboveground stories in height. It should be noted thatmodel building codes contain special allowances for pedestal or podium-style buildings, which permit thestory height for structures above the pedestal to be measured from the top surface of the pedestal, ratherthan from grade plane, and it is the intent of NFPA 13R to follow this model building code method fordetermining the number of stories. Accordingly, it is possible for a four-story residential structure to bewithin the scope of NFPA 13R even when that structure is constructed on top of a one-story pedestal.However, where this is allowed, model building codes will require the pedestal portion to be constructedusing Type I construction, and the pedestal portion will be required to be protected by an NFPA13–compliant sprinkler system.

Regardless of whether a building does or does not involve a pedestal, NFPA 13R systems are alwayslimited to structures that do not exceed 60 ft (18 m) in height above grade plane. Note that model buildingcodes do not allow building height to be measured from the top of a pedestal. That allowance only appliesto determining the number of stories. The 60-foot overall height limit is consistent with limits established bymodel building codes for buildings of Type V construction. The height of a structure above grade plane isdetermined by model building codes, which base the height on the average height of the highest roofsurface above grade plane. For further information on the building height story limits, see model buildingcodes.

Buildings that contain multiple occupancies (either separated or nonseparated), accessory occupancies, orincidental uses are often subject to special rules that might restrict the use of NFPA 13R. In buildingscontaining a residential occupancy properly separated from other occupancies, the use of NFPA 13R in theresidential occupancy and NFPA 13 in the non residential occupancy(s) is appropriate. Refer to theadopted building code to determine whether such restrictions are applicable.

The criteria in this standard are based on full-scale fire tests of rooms containing typical furnishings found inresidential living rooms, kitchens, and bedrooms. The furnishings were arranged as typically found indwelling units in a manner similar to that shown in Figure A.1.1(a), Figure A.1.1(b), and Figure A.1.1(c).Sixty full-scale fire tests were conducted in a two-story dwelling in Los Angeles, California, and 16 testswere conducted in a 14 ft (4.3 m) wide mobile home in Charlotte, North Carolina. Sprinkler systemsdesigned and installed according to this standard are expected to prevent flashover within the compartmentof origin where sprinklers are installed in the compartment. A sprinkler system designed and installedaccording to this standard cannot, however, be expected to completely control a fire involving fuel loads

that are significantly higher than average for dwelling units [10 lb/ft2 (49 kg/m2)], configurations of fuelsother than those with typical residential occupancies, or conditions where the interior finish has anunusually high flame spread index (i.e., greater than 225).

To be effective, sprinkler systems installed in accordance with this standard need to open the sprinklersclosest to the fire before the fire exceeds the ability of the sprinkler discharge to extinguish or control thefire. Conditions that allow the fire to grow beyond that point before sprinkler activation or that interfere withthe quality of water distribution can produce conditions beyond the capabilities of the sprinkler systemdescribed in this standard. Unusually high ceilings or ceiling configurations that tend to divert the rising hotgases from sprinkler locations or change the sprinkler discharge pattern from its standard pattern canproduce fire conditions that cannot be extinguished or controlled by the systems described in this standard.

NFPA 13R references NFPA 13 in many aspects (i.e., hanging and bracing, design densities and spacingoutside of dwelling unit, painting and finish of sprinklers, welding, and so on). If this standard does notspecifically address a situation, NFPA 13 is a good resource that can be utilized by the installer and theauthority having jurisdiction for a solution. It is not the intent of this standard to require compliance withNFPA 13 when NFPA 13R is silent on a subject. Only AHJ approval should be required.

A.3.3.10 Residential Occupancies.

Buildings that contain multiple occupancies, either separated or nonseparated; accessory occupancies; orincidental uses are often subject to special rules that could restrict the use of NFPA 13R. Refer to theadopted building code to determine whether such restrictions are applicable. NFPA 13R is appropriate foruse in a residential occupancy. In the list of building types included in this definition, there are situationswhere there will be mixed occupancies and NFPA 13R might not be the appropriate sprinkler system forthe non-residential occupancies.


Adding additional explanatory language that mirrors the committee statement from the first draft.

A.6.6.5

An example of an open or exterior corridor, stair, or breezeway is one that is exposed to the outsideatmosphere (temperature). Another example is an exterior wraparound corridor that is typical in a two- tothree-story motel.

Note that although NFPA 13R does not require sprinklers in corridors that are open and attached, theadopted building code might require sprinkler protection in certain open-ended corridors.

The 2015 IBC has added section 903.3.1.2.2, which requires sprinklers in open-ended corridors andassociated stairways that are not separated. This requirement has been included in 1027.6, but the ICC feltit needed to flag the requirement in NFPA 13R. As this committee did with the sprinklers on porches inbuildings of Type 5 construction, it should align with what is found in the IBC.


This appears to have been substantiation text and not annex material.

A.6.6.6

Concealed spaces are permitted to have small openings such as grilles for return air when the space isbeing used as a plenum. Such small openings do not disqualify the space from being considered as aconcealed space, and sprinklers are still permitted to be omitted. (See Section 7.5 for 4 for additionalinformation on attic sprinklers.)

A.7.4.3

NFPA 13R does not require installation of sprinklers in attics that are not intended for occupancy orstorage. However storage. Model building codes do not allow habitation in attics. The presence of an atticaccess or scuttle hole does not determine that the attic is intended for storage. However , model buildingcodes sometimes require protection of attics in tall, combustible-framed residential occupancies that areotherwise allowed to follow NFPA 13R. Such protection is permitted to be provided by sprinklers or othermeans allowed by the model building code or NFPA 13, as specified for protection of combustibleconcealed spaces. Common methods of protection in lieu of sprinklers include filling the space withnoncombustible insulation, using fire-retardant-treated wood, or using noncombustible materials. Eventhough sprinklers are not mandatory for attic protection under NFPA 13R, NFPA 13R offers appropriatedesign requirements for cases where sprinklers are provided and sets design benchmarks that parallelwhat is permitted for garages.


Clarification is needed that the presence of an attic access does not mean the attic will be used for occupancy or storage.

Table A.9.3.1 (a) and Table A.9.3.1 (b) can be reresent one conservative method that can be used todetermine a domestic design demand. Using The method is conservative because the tables date back toa time before low low fixtures were in common use. Starting with Table A.9.3.1 (a), the total number ofwater supply fixture units downstream of any point in the piping serving both sprinkler and domestic needsis determined. Using Then, using Table A.9.3(b), the appropriate total flow allowance is determined andadded to the sprinkler demand at the total pressure required for the sprinkler system at that point. If lowflow fixtures are used, the Authority having jurisdiction is permitted to approve other methods of detemininga reasonable domestic demand to add to the sprinkler demand.

Public Comment No. 46-NFPA 13R-2017 [ New Section after B.3 ]

Annex C Press-Connect Fittings used in Fire Sprinkler Applications

(See separate document for proposed text of Annex)



NFPA_13R_Public_Comment_Annex_Information_Press_Connect_Viega_Submitted.docx

NFPA 13R Public Comment Proposed Annex C


Currently there is no definition for Press-Connect fittings in NFPA 13R. The term Press-Connect Fitting is used in both the IAPMO and ICC codes. The wide use of Mechanical type fittings has created the need to identify fittings such as Press-Connect and provide definitions to prevent confusion between mechanical fitting types and to help identify the correct standards these fittings are typically listed to. The proposed annex provides reference information which will be helpful in distinguishing between Mechanical type fittings and Press-Connect Fittings.

In the first draft review meetings our public comments 60, 71, 72, 98, and 99 were resolved because all press-connect systems require listings and thus are not to be listed in the existing tables for standards whose products do not require separate listings.

It was suggested by a few committee members that information on Press-Connect fittings be added instead to the Annex of this code for reference and informational purposes.

Proposed New Annex

Annex C Press‐Connect Fittings used in Fire Sprinkler Applications This annex is not a part of the requirements of this NFPA document but is included for informational purposes only.

This annex is intended to provide basic information and description of press‐connect fittings for metallic

piping systems used in fire sprinkler systems. All press‐connect fitting systems used in fire sprinkler

applications require listing(s) specific to the application. Because press‐connect fittings are not

specifically included in the mandatory sections of this standard the following information will discuss the

press‐connect fitting connection in more detail.

C.1 Definition of Press‐Connect Fittings

The press‐connect fitting is a permanent mechanical connection for joining copper tubing or steel pipe

typically utilizing an elastomeric seal or an elastomeric seal in conjunction with a corrosion resistant

axial biting or grip ring or rings. Fitting connections are generally pressed with an electro‐hydraulic

pressing tool utilizing pressing jaws or pressing rings approved by the fitting manufacturer for use in

accordance with their listing.

C.2 Applications of Press Connect Fittings

Press‐connect fittings are commonly used today in both dry (pre‐action) systems as well as wet systems.

Press‐connect system designs must not exceed the maximum pressure and ambient exposure

temperature ratings for fittings and piping. The maximum continuous exposure temperature is limited

by the elastomeric sealing element material. A manufacturers’ listing will specify the maximum

continuous exposure temperatures for their press‐connect system.

C.3 Standards for Press‐Connect Fittings

Press‐connect systems are generally manufactured in accordance with ASME B16.51, Copper and

Copper Alloy Press‐Connect Pressure Fittings; or IAPMO PS‐117, Press and Nail Connections; or ASTM

F3226/F326M, Standard Specification for Metallic Press‐Connect Fittings for Piping and Tubing Systems

depending on the type of piping. These standards specify the material requirements and the

performance criteria such as, but not limited to, Hydrostatic Pressure Test, Static Torque Test, Bending

Test, Vacuum Test, Pressure Cycle Test, Vibration Test, Thermocycling Test, and Dynamic Torque Test.

C.4 General Assembly Procedure for Press‐Connect Fittings

Press‐connect fittings all have an elastomeric seal that forms the seal‐tight joint. The pipe or tubing is

cut square, deburred and chamfered and, or reamed to restore the full inside diameter. The ends of the

pipe or tube that will be inserted into the fittings should be carefully inspected for any noticeable

damage or deep scratches and also checked and cleaned if any foreign matter such as dirt or tape

residue is present. The pipe or tubing is then fully inserted into the fitting until the internal shoulder

stop is reached and the tubing is then marked with a permanent marker where the tubing meets the

outer shoulder of the fitting in order to establish the full insertion depth. With the tubing fully inserted

139

and the insertion depth mark double checked, the joint can be pressed using the tool recommended by

the manufacturer. The insertion depth mark should be checked once again after pressing to insure the

joint did not slip apart during the pressing operation. Pressure testing of completed sections should

then be conducted per the manufacturer’s instructions and this code to insure all joints are seal tight.
