1.0 Pre-Installation Requirements

SECTION I - PRE-INSTALLATIONREQUIREMENTS

1.1 Removal of an Existing Boiler from aCommon Vent System

Do not install the PRESTIGE into a common ventwith any other gas or oil appliances. This will causeflue gas spillage or appliance malfunction, resultingin possible severe personal injury, death or sub-stantial property damage.

When an existing boiler is removed from a commonventing system, the common venting system is likely tobe too large for proper venting of the remaining appli-ances. At the time of removal of an existing boiler, thefollowing steps shall be followed with each applianceremaining connected to the common venting systemplaced in operation, while the other appliances remain-ing connected to the common venting system are not inoperation.

1. Seal any unused openings in the common ventingsystem.

2. Visually inspect the venting system for proper sizeand horizontal pitch and determine there is noblockage or restriction, leakage, corrosion and otherdeficiencies which could cause an unsafe condition.

3. Insofar as is practical close all building doors andwindows and all doors between the space in whichthe appliances remaining connected to the commonventing system are located and other spaces of thebuilding. Turn on clothes dryers and any appliancenot connected to the common venting system. Turnon any exhaust fans, such as range hoods andbathroom exhausts, so they will operate at maxi-mum speed. Do not operate a summer exhaust fan.Close fireplace dampers.

DANGER

4. Place in operation the appliance being inspected.Follow the lighting instructions. Adjust thermostat soappliance will operate continuously.

5. Test for spillage at the draft hood relief opening after5 minutes of main burner operation. Use the flameof a match or candle, or smoke from a cigarette,cigar or pipe.

6. After it has been determined that each applianceremaining connected to the common venting systemproperly vents when tested as outlined above,return doors, windows, exhaust fans, fireplacedampers and any other gas-burning appliance totheir previous condition of use.

7. Any improper operation of the common venting sys-tem should be corrected so the installation conformswith the National Fuel Gas Code, ANSIZ223.1/NFPA 54 and/or CAN/CSA B149.1 ,Installation Codes. When resizing any portion of thecommon venting system, the common venting sys-tem should be resized to approach the minimumsize as determined using the appropriate tables inPart 11 of the National Fuel Gas Code, ANSIZ223.1/NFPA 54 and/or CAN/CSA B149.1,Installation Codes.

1.2 Vent/Combustion Air Piping andMaterials

The installation must conform to the requirements ofthe authority having jurisdiction or, in the absence ofsuch requirements, to the National Fuel Gas Code,ANSI Z223.1/ NFPA 54, and/or Natural Gas andPropane Installation Code, CAN/CSA B149.1.

The Prestige is certified per ANSI Z21.13 as a CategoryIV (indoor air) or Direct Vent (sealed combustion) appli-ance. A Category IV appliance utilizes uncontaminatedindoor or outdoor air (surrounding the appliance) forcombustion. A Direct Vent appliance utilizes uncontami-nated outdoor air (piped directly to the appliance) forcombustion.

To reduce the potential risks associated with indoorcontaminates (listed on page 12), flammable vaporsand tight housing construction (little or no infiltra-tion air), it is recommended to pipe uncontaminatedcombustion air directly from the outdoors to theappliance.This practice also promotes higher sys-tem efficiency by reducing heated indoor air frombeing exhausted from the building and replaced bycold infiltration air.

The Prestige requires a Category IV venting system whichis designed for pressurized venting and condensate.

The vent and combustion air materials (piping, fit-tings and cement) must meet the listed require-ments in this manual. Failure to comply with thesematerial requirements could result in severe per-sonal injury, death or substantial property damage.

1.5 Combustion Air Contamination

If the PRESTIGE combustion air inlet is located in anarea likely to cause or contain contamination, thecombustion air must be repiped and terminated atanother location. Contaminated combustion air willdamage the unit and its burner system, resulting inpossible severe personal injury, death or substantialproperty damage.

Do not operate the PRESTIGE if its combustion airinlet is located near a laundry room or pool facility.These areas will always contain hazardous con-taminants.

Pool and laundry products, common household andhobby products often contain fluorine or chlorinecompounds. When these chemicals pass throughthe burner and vent system, they can form strongacids. These acids will corrode the heat exchanger,burner components and vent system, causing seri-ous damage and presenting possible flue gasspillage or water leakage into the surrounding area.

Please read the information listed below. If contam-inating chemicals are located near the area of thecombustion air inlet, the installer should pipe thecombustion air inlet to an outside area free of thesechemicals.

DANGER

WARNING

Potential contaminating products- Spray cans containing chloro/fluorocarbons- Permanent Wave Solutions- Chlorinated wax - Chlorine - based swimming pool chemicals /

cleaners- Calcium Chloride used for thawing ice- Sodium Chloride used for water softening- Refrigerant leaks- Paint or varnish removers- Hydrochloric acid / muriatic acid- Cements and glues- Antistatic fabric softeners used in clothe dryers- Chlorine-type bleaches, detergents, and clean-

ing solvents found in household laundry rooms- Adhesives used to fasten building products and

other similar productsAreas likely to contain these products- Dry cleaning / laundry areas and establishments- Beauty salons- Metal fabrication shops- Swimming pools and health spas- Refrigeration Repair shops- Photo processing plants- Auto body shops- Plastic manufacturing plants- Furniture refinishing areas and establishments- New building construction- Remodeling areas- Garages with workshops

2.0 Direct Vent Installation of Vent/Air Piping

13

SECTION II - DIRECT VENT INSTALLATIONOF VENT/AIR PIPING

A Direct Vent appliance utilizes uncontaminated outdoorair (piped directly to the appliance) for combustion.

2.1 Direct Vent - Vertical - Through the Roofor Unused Chimney

The installation must conform to the requirements ofthe authority having jurisdiction or, in the absenceof such requirements, to the National Fuel GasCode, ANSI Z223.1/ NFPA 54, and/or Natural Gas andPropane Installation Code, CAN/CSA B149.1.

When using an inoperative chimney as a means of achase for the vent, the surrounding space within thechimney cannot be used to draw combustion air orvent another appliance.

A gas vent extending through a roof should not ter-minate near an adjacent wall or below any buildingextensions such as roof eaves, balconies or decks.Failure to comply with the required clearances inthis manual could result in severe personal injury,death or substantial property damage.

The information and diagrams outlining the fittingsand method of terminating the vent/combustion airare directly related to PVC/CPVC vent systems.When utilizing and AL29-4C or Polypropylene ventsystem there may be some variations. Consult theappropriate vent manufacturer for recommenda-tions and clarifications.

2.1.1 Determine Termination Location

Locate the vent and combustion air termination using thefollowing guidelines:1. The total length of the vent or combustion air piping

must not exceed the limits given in Table 8 on page 10.

WARNING

NOTICE

NOTICE

NOTICE

Do not include the two 90 elbows used to terminatethe combustion air inlet exterior of the buildingwhen determining the total length of pipe.2. The combustion air piping must terminate in an

upside down U shape fashion using two 90elbows as shown in Fig. 1 page 14. The terminationmust be installed 12 [30.5 cm] (18 [45.7 cm]Canada) above the highest anticipated snow level.

3. The vent must terminate vertically with a coupling toaccept the bird screen and must be located 12 to 24[30.5 cm to 61 cm] above the combustion air inlet asshown in Fig. 1 on page 14.

4. The vent and combustion air terminations must belocated a radial distance of 12 to 24 [30.5 cm to 61cm] from centerline of vent termination to centerlineof air termination as shown in Fig. 1 on page 14.

5. The following should be considered when deter-mining the location of the vent and combustion airterminations:a. Locate the vent termination where flue vapors

will not damage surrounding shrubs, plants orair conditioning equipment or be objectionableto the homeowner.

b. The flue products will form a noticeable plume ofwater vapor as they condense in colder air.Avoid terminating the vent in areas where theplume could obstruct window views.

c. Prevailing winds could cause freezing of fluegas condensation and a buildup of water / ice onsurrounding plants, building surfaces or com-bustion air inlet.

d. Avoid locations where prevailing winds couldaffect the performance of the boiler or causerecirculation of the flue gases, such as insidecorners of buildings, near adjacent buildings,vertical surfaces, window wells, stairwells,alcoves, courtyards, or other recessed areas.

e. Do not terminate the vent above doors or win-dows: flue condensate could freeze causing iceformations.

f. Locate the vent termination to prevent possiblecondensate damage to exterior finishes.

g. Avoid locations of possible accidental contact offlue vapors with people or pets.

This section outlines the installation of Venting andCombustion Air for the PRESTIGE Solo 80, 110 andEXCELLENCE 110 when the vent system must tran-sition from the 3 outlet of the boiler to the 2 (60mm) vent system. The transition from 3 vent system to 2 (60 mm)

vent system must occur at the boiler vent outlet. The transition from 3 vent to 2 (60 mm) vent must

occur in a vertical run only.

Transition of 3 vent to 2 (60 mm) vent in a horizon-tal run may result in pooling of the condensate andpotential vent blockage. Failure to comply can resultin death, serious injury or substantial property dam-age. Use a 3 x 2 bell reducer to make the transition to 2

CPVC/PVC vent, see Figures 20 and 21.* Use a 3 (80 mm) appliance vent adapter and 3 (80

mm) to 2 (60 mm) reducer to make the transition to2 (60 mm) Polypropylene vent see Table 2 on page5.

The 2 (60 mm) vent should not transition back to 3(80 mm) vent at any point in the vent system.

The PVC combustion air piping shall transition from 3to 2 using a 3 x 2 bell reducer and shall transition ina similar manner as the vent system.

The total equivalent length of the 3 (80 mm) ventand 2 (60 mPVC m) vent combined shall notexceed the length listed for a 2 (60 mm) vent sys-tem Table 8 on page 10.

4.2 Insert Piping to PRESTIGE Adapters1. The installer must clean, deburr and chamfer the

pipe ends.

The pipe ends must be smooth, free of sharp edgeschamfer and wiped clean to prevent possible dam-age to the sealing gasket in the vent and combustionair adapters. Failure to comply with this require-ment could result in leakage of flue products caus-ing possible severe personal injury or death.2. Prior to inserting the pipe, inspect the vent and com-

bustion air adapters to verify there are no obstruc-tions or packing material inside the adapters and thegaskets are in place.

3. Ensure the adapter banding strap is loose prior toinserting the pipe.

4. Apply a small amount of silicon grease or water tothe insertion end of the pipe to ease insertion intothe adapter.

5. Insert the pipe into the adapter until it is fully seated.

Do not apply excessive force, twist or bend theadapter or vent / combustion air pipe when insert-ing. The adapter gasket could be damaged resultingin possible flue gas leakage.

6. Secure the vent and combustion air pipe by tighten-ing the adapter banding strap. Do not over tightenthe strap. The seal is made with gasket inside theadapter.
