ASSEMBLYContinued

Today’s homes are built more energy effi-cient than ever. New materials, increasedinsulation, and new construction methodshelp reduce heat loss in homes. 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.

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

AIR FORCOMBUSTION ANDVENTILATION

Confined and Unconfined Space

The National Fuel Gas Code ANS Z223.1defines a confined space as a space whosevolume is less than 50 cubic feet per 1,000Btu per hour (4.8 m3 per kw) of the aggre-gate input rating of all appliances installedin that space and an unconfined space as aspace whose volume is not less than 50cubic feet per 1,000 Btu per hour (4.8 m3 perkw) of the aggregate input rating of allappliances installed in that space. Roomscommunicating directly with the space inwhich the appliances are installed*, throughopenings not furnished with doors, are con-sidered a part of the unconfined 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.

PROVIDING ADEQUATEVENTILATIONThe following are excerpts from NationalFuel Gas Code, NFPA 54/ANS Z223.1, Sec-tion 5.3, Air for Combustion and Ventilation.

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

1. Unusually Tight Construction2. Unconfined Space3. Confined Space

The information on pages 5 through 7 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, in

buildings of unusually tight construction,you must provide additional fresh air.

Unusually tight construction is de-fined as construction where:a. walls and ceilings exposed to the

outside atmosphere have a con-tinuous water vapor retarder witha rating of one perm (6 x 10 -11 kgper pa-sec-m 2) or less with open-ings gasketed or sealed and

b. weather stripping has beenadded on openable windows anddoors and

c. 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 7 .

If your home does not meet all of thethree criteria above, proceed to Deter-mining Fresh-Air Flow For HeaterLocation, page 6.

WARNING: This heater shallnot be installed in a confined 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.

Continued

6 104434


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, Section 5.3 or applicable local codes.

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/Hr

Vented gas heater _____________________ Btu/Hr

Gas fireplace logs _____________________ 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/Hr used)

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

60,000 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 7.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.

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/Hr the space can support, the space is an unconfined space. You will need noadditional fresh air ventilation.

Example:Gas water heater 30,000 Btu/Hr

Vent-free heater + 30,000 Btu/Hr

Total = 60,000 Btu/Hr

This fresh air would come from an adjoiningunconfined space. When ventilating to anadjoining unconfined space, you must pro-vide two permanent openings: one within12" of the ceiling and one within 12" of thefloor on the wall connecting the two spaces(see options 1 and 2, Figure 8). You can alsoremove door into adjoining room (see op-tion 3, Figure 8). Follow the National FuelGas Code, NFPA 54/ANS Z223.1, Section5.3, Air for Combustion and Ventilation forrequired size of ventilation grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilationgrills or ducts. You must provide two per-manent openings: one within 12" of theceiling and one within 12" of the floor.Connect these items directly to the outdoorsor spaces open to the outdoors. These spacesinclude attics and crawl spaces. Follow theNational Fuel Gas Code, NFPA 54/ANSZ223.1, Section 5.3, Air for Combustion andVentilation for required size of ventilationgrills or ducts.

IMPORTANT: Do not provide openings forinlet or outlet air into attic if attic has athermostat-controlled power vent. Heated airentering the attic will activate the power vent.

CONNECTING TO GASSUPPLY

WARNING: A qualified serviceperson must connect heater togas supply. Follow all local codes.

CAUTION: Never connectheater directly to the propane/LPsupply. This heater requires an ex-ternal regulator (not supplied). In-stall the external regulator betweenthe heater and propane/LP supply.

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

The installer must supply an external regu-lator. The external regulator will reduceincoming gas pressure. You must reduceincoming gas pressure to between 11 and 14inches of water. If you do not reduce incom-ing gas pressure, heater regulator damagecould occur. Install external regulator withthe vent pointing down as shown in Figure20. Pointing the vent down protects it fromfreezing rain or sleet.

We recommenc that you install a sedimenttrap in supply line as shown in Figure 21.Locate sediment trap where it is withinreach for cleaning. Install in piping systembetween fuel supply and heater. 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.

IMPORTANT: Hold pressure regulator withwrench when connecting it to gas pipingand/or fittings.

Propane/LPSupply Tank

ExternalRegulator

Installation must include a equipment shutoffvalve, union, and plugged 1/8" NPT tap.Locate NPT tap within reach for test gaugehook up. NPT tap must be upstream fromheater (see Figure 21).

IMPORTANT: Install an equipment shutoffvalve in an accessible location. The equip-ment shutoff valve is for turning on orshutting off the gas to the appliance.

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

The thermostatic control used on thisheater differs from standard thermostats.Standard thermostats simply turn on andoff the burner. The thermostat used onthis 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 temperature.If so, the burner will shut off. The burnerwill cycle back on when room temperaturedrops below the set temperature.

The control knob can be set to any heatlevel 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.

CABINET

Air Passageways• Use a vacuum cleaner or pressurized air

to clean.

Exterior• Use a soft cloth dampened with a mild

soap and water mixture. Wipe the cabi-net to remove dust.

CLEANING BURNERINJECTOR HOLDER ANDPILOT AIR INLET HOLEThe primary air inlet holes allow the properamount of air to mix with the gas. This pro-vides a clean burning flame. Keep these holesclear of dust, dirt, lint, and pet hair. Cleanthese air inlet holes prior to each heatingseason. Blocked air holes will create soot. Werecommend that you clean the unit every threemonths of during operation and have heaterinspected yearly by a qualified service person.

We also recommend that you keep the burnertube and pilot assembly clean and free ofdust and dirt. To clean these parts we recom-mend using compressed air no greater than30 PSI. Your local computer store, hard-ware store, or home center may carry com-pressed air in a can. You can use a vacuumcleaner in the blow position. If using com-pressed air in a can, please follow the direc-tions on the can. If you don't follow direc-tions on the can, you could damage the pilotassembly.

1. Shut off the unit, including the pilot.Allow the unit to cool for at least thirtyminutes.

2. Inspect burner, pilot, and primary airinlet holes on injector holder for dustand dirt (see Figure 30).

3. Blow air through the ports/slots andholes in the burner.

Figure 30 - Injector Holder On OutletBurner Tube

4. Check the injector holder located at theend of the burner tube again. Removeany large particles of dust, dirt, lint, orpet hair with a soft cloth or vacuumcleaner nozzle.

5. Blow air into the primary air holes onthe injector holder.

6. In case any large clumps of dust havenow been pushed into the burner repeatsteps 3 and 4.

Clean the pilot assembly also. A yellow tipon the pilot flame indicates dust and dirt inthe pilot assembly. There is a small pilot airinlet hole about two inches from where thepilot flame comes out of the pilot assembly(see Figure 31). With the unit off, lightlyblow air through the air inlet hole. You mayblow through a drinking straw if compressedair is not available.
