WARNING
When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless,
poisonous gas.
Do not install heater until all necessary provisions are made for
combustion and ventilation air. Consult the written instructions
provided with the heater for information concerning
combustion and ventilation air. In the absence of instructions,
refer to the National Fuel Gas Code, ANSI Z223.1, Section
5.3 or applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY
SYSTEM designed to turn off the heater if not enough fresh air
is available.
DO NOT TAMPER WITH PILOT LIGHT SAFE TY
SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO
DEATH.
Early signs of carbon monoxide poisoning resemble the flu,
with headache, dizziness and/or nausea. If you have these
signs, heater may not be working properly. Get fresh air at
once! Have heater serviced.
Some people – pregnant women, persons with heart or lung
disease, anemia, those under the influence of alcohol, those at
high altitudes – are more affected by carbon monoxide than
others.
The pilot light safety system senses the depletion of oxygen
at its location. If this heater is installed in a structure having a
high vertical dimension, the possibility exists that the oxygen
supply at the higher levels will be less than that at the heater. In
this type of application, a fan to circulate the structure air will
minimize this effect. The use of this fan will also improve the
comfort level in the structure. When a fan is used to circulate
air, it should be located so that the air flow is not directed at
the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires and
explosions. In its natural state, propane is odorless and colorless.
You may not know all the following safety precautions which
can protect both you and your family from an accident. Read
them carefully now, then review them point by point with the
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area.
Do that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling
a gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
members of your household. Someday when there may not be
a minute to lose, everyone's safety will depend on knowing
exactly what to do. If, after reading the following information,
you feel you still need more information, please contact your
gas supplier.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels. Always be sensitive to the
slightest gas odor. If you detect any odor, treat it as a serious
leak. Immediately go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the
odor of LP-Gas prior to and while lighting pilot lights or
performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
Page 4 18954-0-0705
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your
A periodic sniff test of the LP-gas is a good safety measure
under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having
it refilled before it is completely empty.

GENERAL INFORMATION
BRUCE SPECIAL COPY
This is an unvented gas-fired heater. It uses air (oxygen) from the
room in which it is installed. Provisions for adequate combustion
and ventilation air must be provided.
Keep room area clear and free from combustible materials,
gasoline and other flammable vapors and liquids.
Unvented gas heaters are a supplemental zone heater. They are not
intended to be a primary heating appliance. Water vapor produced
by an unvented heater can create moisture problems in a home
when operated for extended periods of time.
During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils, films or
bonding agents. These chemicals are not harmful but may produce
annoying smoke and smells as they are burned off during the initial
operation of the appliance; possibly causing headaches or eye or
lung irritation. This is a normal and temporary occurrence.
The initial break-in operation should last 2-3 hours with the burner
at the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remaining
after this initial break-in period will be slight and will disappear
with continued use.
This appliance must not be used with glass doors in the closed
position. This can lead to pilot outages and severe sooting outside
the fireplace.
Do not use this room heater if any part has been under water.
Immediately call a qualified service technician to inspect the
room heater and replace any part of the control system and any
gas control which has been under water.

Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equipment or accessories and repair and servicing of equipment shall
be performed only by a qualified agency. The term "qualified
agency" means any individual, firm, corporation, or company
that either in person or through a representative is engaged in and
is responsible for (a) the installation, testing, or replacement of
gas piping or (b) the connection, installation, testing, repair, or
servicing of equipment; that is experienced in such work; that is
familiar with all precautions required, and that has complied with
all the requirements of the authority having jurisdiction.
State of Massachusetts: The installation must be made by
a licensed plumber or gas fitter in the Commonwealth of
Massachusetts.
Sellers of unvented propane or natural gas-fired supplemental
room heaters shall provide to each purchaser a copy of 527
CMR-30 upon sale of the unit.
The installation must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code, ANSI Z223.1.*
*Available from the American National Standards Institute, Inc. 11 West 42nd
St., New York, N.Y. 10018.
High Altitudes: For altitudes/elevation above 2,000 feet ratings
should be reduced at the rate of 4 percent for each 1,000 feet above
sea level. Contact the manufacturer.
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for
every 1,000 BTU's (.3KW's) of gas input per hour.
Unvented room heaters must be used as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
Page 6 18954-0-0705
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used
to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source
(an entire house).
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
This heater shall not be installed in a confined space unless provisions
are provided for adequate combustion and ventilation air.
The National Fuel Gas Code defines a confined space as a space whose
volume is less than 50 cubic feet per 1,000 Btu per hour (4.8m
of the aggregate input rating of all appliances installed in that space and
an unconfined space as a space whose volume is not less than 50 cubic
feet per 1,000 Btu per hour (4.8 m3 per 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 furnished with doors, are considered a part of the unconfined space.
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 exposed to the outside atmosphere have a
continuous water vapor retarder with a rating of one perm or less
with openings gasketed or sealed, and
b. Weatherstripping 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, 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.
Warning: If the area in which the heater may be operated is smaller than
that defined as an unconfined space or if the building is of unusually tight
construction, provide adequate combustion and ventilation air by one
of the methods described in the National Fuel Gas Code, ANSI Z223.1,
Section 5.3. or applicable local codes.
