aected by carbon monoxide than others: pregnant women, people with heart or lung disease, people
who are anemic, those under the influence of alcohol, and those living in high altitudes.
NATURAL AND PROPANE GAS: Natural and propane gases are odorless. An odor-making agent is added
to the gas. The odor helps you detect a gas leak. However, the odor added to the gas can fade. Gas may
be present even though no odor exists. Make certain you read and understand all warnings. Keep this
manual for reference. It is your guide to operating this heater safely.

WARNING:
• This heater must only be used with the type of gas indicated on the rating label. This heater is not
convertible for use with other gases.
• Do not place propane supply tank(s) inside any structure. Place propane supply tank(s) outdoors.
• If you smell gas, do the following:
• Shut off the gas supply;
• Do not try to light any appliance;
• Do not touch any electrical switch, and 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, contact the fire department.
• Before using furniture polish, wax, carpet cleaner, or similar products, turn the heater o. If heated, the
vapors from these products may create a white powder residue within the burner box or on adjacent
walls or furniture.
• This heater must never be installed in a bedroom or bathroom.
• This heater needs fresh air ventilation to run properly and safely. This heater has an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS shuts down the heater if not enough fresh air is

Preparing for Installation
WATER VAPOR IS A BY-PRODUCT OF UNVENTED ROOM HEATERS
Gas combustion creates water vapor as a by-product. Unvented room heaters create about one (1) ounce (30
ml) of water for every 1,000 BTUs (0.3 kW) of gas input per hour. An unvented room heater is recommended
as a supplemental heat source for a single room rather than as a primary heat source for an entire house. The
water vapor does not typically create a problem. In most cases, the water vapor enhances the low humidity
conditions that are typical of cold weather.
Keep these points in mind so that the water vapor does not create a problem:
• The heater must be the proper size for the application. Provide adequate combustion air and circulation air.
• In humid environments, use a dehumidifier to help lower the amount of water vapor in the air.
• Do not use an unvented room heater as your primary heat source.
AIR FOR COMBUSTION AND VENTILATION
This heater shall not be installed in a room or space unless the required volume of indoor combustion air is
provided by the method described in the National Fuel Gas Code, ANS Z223.1/NFPA 54, the International Fuel
Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
Spaces in homes can be divided into these ventilation classifications:
• Unusually Tight Construction
• Unconfined Space
• Confined Space
The information on pages 8–10 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space:
A confined space has a volume less than 50 cu. ft. per 1,000 BTU/hr (4.8 m3 per kW) of the total input rating
of all appliances installed in that space. An unconfined space has a volume not less than 50 cu. ft. per
1,000 BTU/hr (4.8 m3 per kW) of the total input rating of all appliances installed in that space. Rooms that
are directly connected to the space in which the appliances are installed*, through openings that do not
have doors, are considered a part of the unconfined space.
Do not install this heater in a confined space or unusually tight construction unless you provide
provisions for adequate combustion and ventilation air.
*Adjoining rooms are directly connected only if there are doorless passageways or ventilation grills between them.
Unusually Tight Construction:
Doors and windows may leak air that provides enough fresh air for combustion and ventilation. However,
you must provide additional fresh air in buildings of unusually tight construction. Unusually tight
construction is defined as construction that meets the following criteria:
A. Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a
rating of one perm or less with openings that are gasketed or sealed.
B. Doors and windows that can be opened have weather stripping.
C. Caulking or sealants are applied to areas such as 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 residence meets all the above criteria, additional fresh air must be provided. See VENTILATION AIR
FROM OUTDOORS on page 10 for more information. If your residence does not meet those three criteria,
continue to DETERMINING FRESH-AIR FLOW FOR THE HEATER LOCATION.

DETERMINING FRESH-AIR FLOW FOR THE HEATER LOCATION
Determining if You Have a Confined or Unconfined Space:
Use the below information to determine if you have a confined or unconfined space. Your space includes
the room in which you will install the heater plus any other rooms that are directly connected and have
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space. Length × Width × Height = cu. ft. (volume of space)
• Example: 20 ft. (length) × 16 ft. (width) × 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
If additional ventilation to adjoining room(s) is supplied with grills or openings, add the volume of these
rooms to the total volume of your space.
2. Divide the space’s volume by 50 cu. ft. 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:
Example:
Gas heater __________BTU/hr Gas water heater 40,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 30,000 BTU/hr
Total = ____BTU/hr Total = 70,000 BTU/hr
*Do not include direct-vent gas appliances. Direct-vent appliances draw combustion air from outdoors
and vent 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) 70,000 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. Add the space of an adjoining room and rework the above information. If the extra space creates an
unconfined space, remove the door to the adjoining room or add ventilation grills between rooms.
See VENTILATION AIR FROM INSIDE A BUILDING, page 10.
B. Vent the room directly to the outdoors. See VENTILATION AIR FROM OUTDOORS, page 10.
C. Install a heater that uses less BTUs/hr if the lower BTUs/hr creates an unconfined space. If the actual BTU/
hr used is less than the maximum BTU/hr the space can support, the space is an unconfined space. In
this case, no additional fresh air ventilation is needed.

methods described in the NATIONAL FUEL GAS CODE, ANS Z223.1/NFPA 54, the INTERNATIONAL FUEL GAS
CODE, or applicable local codes.
VENTILATION AIR FROM INSIDE A BUILDING
Fresh air comes from a connected unconfined space.
You must provide two permanent openings when
ventilating to a connected unconfined space, one of
which that’s within 12" of the wall that connects the
two spaces (see options 1 and 2, Fig. 1). You may also
remove the door into the adjoining room (see option 3,
Fig. 1). Follow the National Fuel Gas Code NFPA 54/ANS
Z223.1 for the required size of ventilation grills or ducts.
VENTILATION AIR FROM OUTDOORS
Extra fresh air is provided via ventilation grills or
ducts. You must provide two permanent openings:
one within 12" of the ceiling and one within 12" of the
floor (see Fig. 2). They must connect directly to the
outdoors or spaces that open to the outdoors. Such
spaces may include attics or crawl spaces. Follow the
National Fuel Gas Code NFPA 54/ANS Z223.1 for the
required size of ventilation grills or ducts.
