• Installation and repair should be done by a QUALIFIED
SERVICE PERSON. The appliance should be inspected
before use and at least annually by a professional service
person. More frequent cleaning may be required due to
excessive lint from carpeting, bedding materials, etc. It
is imperative that control compartments, burners and
circulating air passageways of the appliance be kept
clean.
• DO NOT use this room heater if any part has been under
water. Immediately call a qualied service technician
to inspect the room heater and to replace any part of the
control system and any gas control which has been under
water.
• Keep appliance area clear and free from combustible
materials, gasoline and other ammable vapors and
liquids.
• WARNING: ANY CHANGE TO THIS HEATER OR ITS
CONTROLS CAN BE DANGEROUS.
Any safety screen or guard removed for servicing
an appliance must be replaced prior to operating the
heater.
• WARNING: Failure to keep the primary air opening(s)
of the burner(s) clean may result in sooting and property
damage.
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/NFPA 54, Air for Combustion and Ventilation, 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 SAFETY 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.

WARNING
CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Early signs of carbon monoxide poisoning resemble the u,
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 inuence 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 ow
is not directed at the burner.
SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a ammable gas which can cause res 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 members
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
reghters 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 nd 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 lter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
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 re 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 reghters 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.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
nd 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 qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualied, 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 lled and allowed to set too
long before relling. Cylinders and tanks which have been
out of service for a time may develop internal rust which will
SOME POINTS TO REMEMBER
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 LP-gas dealer. 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 under 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 orices. 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
relled before it is completely empty.

SPECIFICATIONS
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.
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 dehumidier 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 conned space or unusually tight construction unless provisions are provided for adequate
combustion and ventilation air.
A conned space is an area with volume less than 50 cubic feet per
1,000 Btuh of the combined input rates of all appliances drawing
combustion air from that space. Small areas such as equipment
rooms are conned spaces. Furnaces installed in a conned space
which supply heated air to areas outside the space must draw return
air from outside the space through tightly sealed return air ducts. A
conned space must have 2 openings into the space fro combustion
air. One opening must be within 12 inches of the ceiling and the
other must be within 12 inches of the oor. The required sizing of
these openings is determined by whether inside or outside air is
used to support combustion, the method by which the air is brought
to the space (vertical or horizontal duct) and by the total input rate
of all appliances in the space.
The following example is for determining the volume of a typical
area in which the BF-20 may be located and for determining if this
area ts the denition of an unconned space.
The input of the BF-20 is 20,000 Btu per hour. Based on the 50
cubic feet per 1,000 Btu per hour formula, the minimum area that
is an unconned space for installation of the BF-20 is 1,000 cubic
feet, 50 cubic feet x 20 = 1,000 cubic feet. To determine the cubic
feet of the area in which the BF-20 is to be installed, measure the
length, width and height of the area. Example: The area measures
16 feet in length, 8 feet in width and 8 feet in height, the area is
1,024 cubic feet. The BF-20 can be installed in this unconned
space with no requirement to provide additional combustion and
ventilation air.
If the area in which the heater may be operated is smaller than that
dened as an unconned 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/NFPA 54, Air for Combustion and Ventilation,
or applicable local codes.
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 dened 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. 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, between sole plates and
oors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at
other openings.
If the heater is installed in a building of unusually tight construction,
adequate air for combustion, ventilation and dilution of ue gases
shall be provided in accordance with ANSI Z223.1/NFPA54.
