may result causing property damage, per-
sonal injury, or loss of life.
— Do not store or use gasoline or other
flammable vapors and liquids in the vicinity of
this or any other appliance.
— WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not
use any phone in your building.
• Immediately call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
• If you cannot reach your gas supplier, call
the fire department.
— Installation and service must be performed
by a qualified installer, service agency, or the
gas supplier.

tion,adjustment,alteration,ser-
vice, or maintenance can cause
injury or property damage. Re-
fer to this manual for correct
installation and operational
procedures. For assistance or

1. Use only natural gas. Do not convert
heater to use different fuel type.
2. If you smell gas
• shut off gas supply
• do not try to light any appliance
• do not touch any electrical switch; do
not use any phone in your building.
• immediately call your gas supplier
from a neighbor’s phone. Follow the
gas supplier’s instructions
• ifyou cannotreach yourgas supplier,
call the fire department
3. This heater shall not be installed in a
bedroom or bathroom.
4. Never install the heater
• in a recreational vehicle
• wherecurtains, furniture,clothing, or
otherflammable objects are less than
36inches fromthe front,top, orsides
of the heater
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
5. This heater needs fresh, outsideair ven-
tilation to run properly.This heater has
an oxygen depletion sensor (ODS) pi-
lot light safety system. The ODS shuts
down the heater if not enough fresh air
is available. See Air for Combustion
and Ventilation, pages 5 through 7.
6. Before using furniture polish,wax, car-
pet cleaner, or similar products, turn
heater off. If heated, the vapors from
these products may creat a white pow-
der residue within burner box or on
adjacent walls or furniture.
7. If heater shuts off, do not relight until
you provide fresh, outside air. If heater
keeps shutting off, have it serviced.
8. Do not run heater
• where flammable liquids or vapors
are used or stored.
• under dusty conditions.
Carbon Monoxide Poisoning: Early
signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness,

AIR FOR
COMBUSTION AND
VENTILATION
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners

doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient,yourhomeneedstobreathe.Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaustfans,fireplaces,clothesdryers,and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following is excerpts from National
Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Venti-
lation.
Allspacesinhomesfallintooneofthethree
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 win-
dows may provide enough fresh air for
combustion and ventilation. However, in
Confined and Unconfined Space
TheNationalFuelGasCode(ANSIZ223.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubicfeetper1,000Btuperhour(4.8m3per
kw) of the aggregate input rating of all
appliances installed in that space and an
unconfiningspaceasaspacewhosevolume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3per kw) of the aggregate
inputratingofallappliancesinstalledinthat
space.Roomscommunicating directly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unlessprovisions areprovidedfor adequate
combustion and ventilation air.

structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
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 with
a rating of one perm (6 x 10-11 kg
per pa-sec-m2) or less with open-
ings gasketed or sealed and
b. weather stripping has been
added on openable windows and
doors and
c. caulking or sealants are applied
to areas such as joints around
window and door frames, be-
tween sole plates and floors,be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsforplumbing,electrical,and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors , page 7 .

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:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween
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)
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of
the 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)
58,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
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 no
additional fresh air ventilation.
Example:
Gas water heater 30,000 Btu/Hr
Vent-free heater +28,000 Btu/Hr
Total =58,000 Btu/Hr

the heater
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
CAUTION: This heater cre-
ates warm air currents. These
currents move heat to wall sur-
faces next to heater. Installing
heater next to vinyl or cloth wall
coverings or operating heater
where impurities (such as to-
bacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls.
IMPORTANT: Vent-free heaters add mois-
ture to the air. Although this is beneficial,
installing heater in rooms without enough
ventilation air may cause mildew to form
from too much moisture. See Air for Com-
bustion and Ventilation, pages 5 through 7.
NOTICE: This heater is intended
