AIR FORCOMBUSTION ANDVENTILATION

WARNING: This heater shallnot be installed Inaconfined spaceor unusually tight constructionunless provisions are providedfor adequate combustion and ven-tilation air. Read the following in-structions to insure proper freshair for this and other fuel-burningappliances in your home.

Today's homes are built more energy effi-cient than ever. New materials, increasedinsulation, and new construction methodshelp reduce heat loss inhomes. Home ownersweather strip and caulk around windows anddoors to keep the cold air out and the warm airin. During heating months, home ownerswant their homes as airtight as possible.

While it is good to make your home energyefficient, your home needs to breathe. Freshair must enter your home. All fuel-burningappliances need fresh air for proper com-bustion and ventilation.

PROVIDING ADEQUATEVENTILATION

The following are excerpts from NationalFuel Gas Code. NFPA 54/ANS Z223.1, Sec-

tion 5.3, Air for Combustion and Ventila-tion.

All spaces in homes fall into one of the threefollowing ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 6 through 8 willhelp you classify your space and provideadequate ventilation.

Unusually Tight Construction

The air that leaks around doors and win-

dows may provide enough fresh air forcombustion and ventilation. However, inbuildings of unusually tight construction,you must provide additional fresh air.

Unusually tight construction is de-fined as construction where:

a°

Exhaust fans, fireplaces, clothes dryers, andfuel burning appliances draw air from thehouse to operate. You must provide ad-equate fresh air for these appliances. This b.will insure proper venting of vented fuel-burning appliances.

g.

walls and ceilings exposed to theoutside atmosphere have a con-tinuous water vapor retarder witha rating of one perm (6x10 "11kgper pa-sec-m =)or less with open-ings gasketed or sealed and

weather stripping has beenadded on openable windows anddoors and

caulking or sealants are appliedto areas such as joints aroundwindow and door frames, be-tween sole plates and floors, be-tween wall-ceiling joints, be-tween wall panels, at penetra-tions for plumbing, electrical, andgas lines, and at other openings.

If your home meets all of the threecriteria above, you must provide ad-ditional fresh air° See Ventilation AirFrom Outdoors, page 8.

If your home does not meet all of thethree criteria above, proceed to Deter-mining Fresh-Air Flow for HeaterLocation, page 7.

Confined and Unconfined Space

The National Fuel Gas Code (ANS Z223. l,1992 Section 5.3) defines a confined spaceas a space whose volume is less than 50cubic feet per 1,000 Btu per hour (4.8 m3perkw) of the aggregate input rating of allappliances installed in that space and anunconfining space as a space whose volumeis not less than 50 cubic feet per 1,000 Btuper hour (4.8 m3per kw) of the aggregateinput rating of all appliances installed in thatspace. Rooms communicating directly withthe space in which the appliances are in-stalled*, through openings not furnishedwith doors, are considered a part of theunconfined space.

This heater shall not be installed in a con-fined space or unusually tight constructionunless provisions are provided for adequatecombustion and ventilation air.

* Adjoining rooms are communicating onlyif there are doorless passageways or ventila-tion grills between them.

AIR FORCOMBUSTION ANDVENTILATIONContinued

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills betweenthe rooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height = cu. ft. (volume of space)

Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume ofthe space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

(volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. =51.2 or 51,200 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free heater Btu/Hr

Gas water heater* Btu/Hr

Gas furnace Btu/FIr Example: Gas water heater 30,000 Btu/Hr

Vented gas heater Btu/Hr Vent-free heater + 28,000 Btu/Hr

Gas fireplace logs Btu/Hr Total = 58,000 Btu/Hr

Other gas appliances* + Btu/Hr

Total = Btu/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

Btu/Hr (maximum the space can support)

Btu/Hr (actual amount of Btu/l-lr used)

Example: 51,200 Btu/Hr (maximum the space can support)

58,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.You must provide additional fresh air. Your options are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 8.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.

C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/I-lr the space can support, the space is an unconfined space. You will need noadditional fresh air ventilation.

WARNING: If the area In which the heater may be operated Is smaller than that defined as an unconfined spaceor If the building is of unusually tight construction, provide adequate combustion and ventilation air by one ofthe methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3, or applicable local codes.

_k WARNING: If installing theGHB802 or GHB802A base onheater, and using with a GA se-ries heater blower accessoryalong with a GS601 surround or aGM800 or GM900 series mantel,the surround or mantel clearanceto back wall should be 3/4 inch.This will improve flame appear-ance and combustion.

Use only a GHB802B, GHB802C,OR GHB38 series hearth base ifusing a GA series heater bloweraccessory with a GM70O series,GMC32F series, or GMC33U se-ries mantel.

CONNECTING TO GASSUPPLY

NOTICE: A qualified service per-son must connect heater to gassupply. Follow all local codes.

WARNING: Never connectheater to private (non-utility) gaswells. This gas is commonlyknown as wellhead gas.

IMPORTANT: Check gas line pressure be-fore connecting heater to gas line. Gas linepressure must be no greater than 14 inchesof water. If gas line pressure is higher,heater regulator damage could occur.

CAUTION : Use only new,black iron or steel pipe. Inter-nally-tinned copper tubing maybe used in certain areas. Checkyour local codes. Use pipe of 1/2"or greater diameter to allowproper gas volume to heater. Ifpipe is too small, undue loss ofpressure will occur.

Installation must include a manual shutoff

valve, union, and plugged 1/8" NPT tap.

Locate NPT tap within reach for test gaugehook up. NPT tap must be upstream fromheater (see Figure 20).

Apply pipe joint sealant lightly to malethreads. This will prevent excess sealantfrom going into pipe. Excess sealant in pipecould result in clogged heater valves.

_k CAUTION: Use pipe ioint seal-ant that is resistant to liquid pe-troleum (LP) gas.

Install sediment trap in supply line as shownin Figure 20. Locate sediment trap where itis within reach for cleaning. Locate sedi-ment trap where trapped matter is not likelyto freeze. A sediment trap traps moistureand contaminants. This keeps them fromgoing into heater controls. If sediment trapis not installed or is installed wrong, heatermay not run properly.

_k CAUTION: Avoid damage tocontrol. Hold gas fitting withwrench when connecting it to gaspiping and/or fittings.

I THERMOSTAT ICONTROL OPERATION

The thermostatic control used on thisheater differs from standard thermostats.

Standard thermostats simply turn on andoff the burner. The thermostat used on

this heater senses the room temperature.The thermostat adjusts the amount of gasflow to the burner. This increases or de-creases the burner flame height. At timesthe room may exceed the set tempera-ture. If so, the burner will shut off. Theburner will cycle back on when roomtemperature drops below the set tem-perature. The control knob can be set toany heat level between HI and LO.

Note:. The thermostat sensing bulb mea-sures the temperature of air near theheater cabinet. This may not always agreewith room temperature (depending onhousing construction, installation loca-tion, room size, open air temperatures,etc.). Frequent use of your heater will letyou determine your own comfort levels.

MANUAL LIGHTING 1PROCEDURE

1. Remove front panel (see Figure 2,page 4).

2. Follow steps 1 through 5 under Light-ing Instructions, page 15.

3. With control knob pressed in, strikematch. Hold match to pilot until pi-lot lights.

4. Keep control knob pressed in for 30seconds after lighting pilot. After 30seconds, release control knob.

5. Replace front panel.

6. Turn control knob counterclockwise

to desired heating level. Themain burner should light. Set controlknob to any heat level between HIand LO.
