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.

Well Head Gas Installations
Some natural gas utilities use "well head" gas. This may affect
the Btu output of the unit. Contact the gas company for the heating value. Contact the manufacturer or your gas company before
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.

NOTICE: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed ame to check for leaks. Appliance must be
disconnected from piping at inlet of control valve and pipe capped
or plugged for pressure test. Never pressure test with appliance
connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required

Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig (3.5
kPa).
3. The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).
Attention! If one of the above procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve,
it will result in a hazardous condition.
Checking Manifold Pressure
Natural gas will have a manifold pressure of approximately 3.5" w.c.
(.87kPa) at the pressure regulator outlet with the inlet pressure
to the pressure regulator from a minimum of 5.0" w.c. (1.245kPa)
for the purpose of input adjustment to a maximum of 10.5" w.c.
(2.615kPa). Propane/LP gas will have a manifold pressure approximately 10.0" w.c. (2.49kPa) at the pressure regulator outlet
with the inlet pressure to the pressure regulator from a minimum
of 11.0" w.c. (2.739kPa) for the purpose of input adjustment to a
maximum of 13.0" w.c. (3.237kPa).
A test gage connection is located downstream of the gas appliance
pressure regulator for measuring gas pressure. The connection is
a 1/8 inch (3mm) N.P.T. plugged tapping.

To light the pilot, it is important that the electrode be 1/8" (3mm)
from the pilot. The spark must occur at the point the pilot ame
hits the thermocouple.
On a new installation with air in the gas line, it is suggested that a
match be used. The match will light the pilot faster than the piezo
under this condition.
There will be a short blue inner ame with a much larger, lighter
blue, secondary ame. The burner ame may have a small yellow
tip when hot. Dust in the combustion air will produce an orange or
red ame. Do not mistake the orange or red ame for an improper
yellow ame. Clean main burner by applying compressed air into
ports and throat of main burner.
Figure 7
Attention: BF-10, Natural or Propane gas has a front and rear air
shutter.
BF-20, Propane gas only has a front air shutter.
Air Shutter Adjustment (Figure 8)
The air shutter on main burner is factory set at a 3/32" opening. If
yellow ames occur on main burner loosen 1/4" screw on air shutter
in order to increase air shutter opening. The slot on air shutter allows
the air opening to be increased or decreased. Tighten 1/4" screw on
air shutter after air shutter adjustment has been completed.

PILOT FLAME CHARACTERISTICS
The correct ame will be blue and will extend beyond the thermocouple. The ame will surround the thermocouple just below the
tip. A slight yellow ame may occur where the pilot ame and main
burner ame meet.
Figure 9
Oxygen Depletion Sensor Pilot (Figure 10)
When the pilot has a large yellow tip ame, clean the Oxygen Depletion Sensor as follows:
1. Remove pilot from main burner assembly, see "Appliance Maintenance", Page 13.
2. Apply air pressure through the holes in the pilot indicated by the
arrows. This will blow out foreign materials such as dust, lint
and spider webs.
Figure 10
WARNING
Never use needles, wires, or similar cylindrical objects to clean
the pilot to avoid damaging the calibrated ruby that controls the
gas ow.
THERMOSTAT OPERATION
To ignite main burner, rotate gas control knob counterclockwise
toward HI setting. To shut down main burner, rotate gas control
knob clockwise toward LO setting.
BF-10
The gas control has an input of 10,000 BTU/HR (2.9 KW/H).
The hydraulic thermostat bulb is located at the casing assembly
bottom.
BF-20
The gas control modulates from a minimum input of 8,500 BTU/
HR (2.5 KW/H) (LO setting) to a maximum input of 20,000 BTU/HR
(5.9 KW/H) for LP gas (HI setting) or 18,000 BTU/HR (5.3 KW/H)
for Natural Gas (HI setting). The hydraulic thermostat bulb which
is located at the casing assembly bottom adjusts the main burner
ame between minimum input and maximum input.
NOTICE: When the hydraulic thermostat bulb is "satised" the main
burner ame will shut "OFF" with the pilot ame remaining "ON".
The LO and HI setting has temperature range of approximately 55°F
(12.78°C) to 90°F (32.22°C) , respectively. This is the temperature at
the hydraulic thermostat bulb not the room temperature. The owner
is advised to determine the particular heat setting that is desired for
comfort, as heating requirements are different for every owner.
Attention: If the owner does not want the main burner to ignite
and turns the gas control knob to the Lo setting, the main burner
will still ignite if the temperature at the hydraulic thermostat bulb
drops to 55°F (12.78°C).
If no heat is desired, turn the gas control knob to the PILOT
position.
