AIR FOR COMBUSTION AND
VENTILATION
Today’s homes are built more energy efficient than ever. New materi-
als, increased insulation, and new construction methods help reduce
heat loss in homes. Home owners weather strip and caulk around
windowsanddoorstokeepthecoldairoutand the warm air in. During
heatingmonths,home owners wanttheirhomes as airtightaspossible.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code,ANSI
Z223.1/ NFPA 54, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation
classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will help you classify your
space and provide adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh air.
Unusually tight construction is defined as construction
where:
a. walls and ceilings exposedtotheoutsideatmosphere
have a continuous water vapor retarder with a rating
of one perm (6 x 10-11 kg per pa-sec-m2) or less with
openings gasketed or sealed and
b. weather stripping has been added on openable win-
dows and doors and
c. caulking orsealantsare applied toareassuchas joints
around window and door frames,between sole plates
and floors, between wall-ceiling joints, between wall
panels, at penetrations for plumbing, electrical, and
gas lines, and at other openings.
If your home meets all of the three criteria above, you
must provide additional fresh air. See Ventilation Air
From Outdoors , page 7.
If your home does not meet all of the three criteria above,
proceed to Determining Fresh-Air Flow For Fireplace
Location , page 6.
WARNING: This heater shall not be installed in a
confined space or unusually tight construction un-
lessprovisions areprovidedfor adequatecombustion
and ventilation air. Read the following instructions to
insure proper fresh air for this and other fuel-burning
appliances in your home.
While it is good to make your home energy efficient, your home
needs to breathe. Fresh air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.
Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances
drawairfromthehousetooperate.Youmustprovideadequatefresh
air for these appliances. This will insure proper venting of vented
fuel-burning appliances.

Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1.3/ NFPA 54 defines a
confined space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m3per kw) of the aggregate input rating
of all appliances installed in that space and an unconfined space as
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper
hour (4.8 m3per kw) of the aggregate input rating of all appliances
installed in that space. Rooms communicating directly with the
space in which the appliances are installed*, through openings not
furnishedwithdoors,areconsideredapart of the unconfined space.
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a
confined space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m3per kw) of the aggregate input rating
of all appliances installed in that space and an unconfined space as
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper

DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space
Usethis worksheet todetermineif youhave aconfined orunconfinedspace.
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining
rooms with doorless passageways or ventilation grills between the 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)
Ifadditional ventilationto adjoiningroom issuppliedwith grillsor open-
ings, add the volume of these rooms to the total volume of the space.
2. Multiply the space volume by 20 to determine the maximum Btu/Hr
the space can support.
__________ (volume of space) x 20 = (Maximum Btu/Hr the space
can support)
Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum
Btu/Hr the space can support)
WARNING: If the area in which the heater may be
operated is smaller than that defined as an uncon-
fined space or if the building is of unusually tight
construction,provideadequatecombustionandven-
tilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec-
tion 5.3 or applicable local codes .
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 com-
bustion air from the outdoors and vents to the outdoors.
Example:
Gas water heater _____________ Btu/Hr
Vent-free heater + _____________ Btu/Hr
Total = _____________ Btu/Hr
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)

CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
CAUTION: Never connect propane/LP fireplace
directly to the propane/LP supply. This fireplace
requires an external regulator (not supplied). Install
the external regulator between the fireplace and
propane/LP supply.
CAUTION:Useonlynew, blackironorsteelpipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
or greater diameter to allow proper gas volume to
fireplace. If pipe is too small, undue loss of volume
will occur.
WARNING:Use pipejointsealantthat is resistant
to liquid petroleum (LP) gas.
For propane/LP units, installer must supply an external regulator.
The external regulator will reduce incoming gas pressure. You
mustreduceincoming gaspressuretobetween11and14 inchesof
water. If you do not reduce incoming gas pressure, fireplace
regulator damage could occur. Install external regulator with the
ventpointingdownasshown in Figure 23.Pointingthevent down
protects it from freezing rain or sleet.

heating season. Blocked air holes will create soot. We recommend
that you clean the unit every three months during operation and have
heater inspected yearly by a qualified service person.
We also recommend that you keep the burner tube and pilot
assembly clean and free of dust and dirt. To clean these parts we
recommendusingcompressedairnogreaterthan30PSI.Yourlocal
computer store, hardware store, or home center may carry com-
pressed air in a can. You can use a vacuum cleaner in the blow
position. If using compressed air in a can, please follow the direc-
tionson thecan.Ifyoudon'tfollowdirectionsonthecan, youcould
damage the pilot assembly.
1. Shut off the unit, including the pilot.Allow the unit to cool for
at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet holes on injector
holder for dust and dirt (see Figure 37).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner tube
again. Remove any large particles of dust, dirt, lint, or pet hair
with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into
the burner repeat steps 3 and 4.
Clean the pilot assembly also. A yellow tip on the pilot flame
indicates dust and dirt in the pilot assembly. There is a small pilot
