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 changing spud/
orifice size.
• 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 qualified 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.
• Due to high surface temperatures, keep children, clothing and
furniture away.
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 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 flu, with
headache, dizziness and/or nausea. If you have these signs, heater
may not be working properly.
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.
Get fresh air at once! Have heater

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
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!
by point with the 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.
• 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
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell
the odor of the chemical stench 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
firefighters declare them to be safe.
• 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.
can occur if 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 find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your LPGas 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
R-4973 Page 3
SOME POINTS TO REMEMBER
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 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 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.

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 are recommended 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 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.
Provisions for Adequate Combustion and Ventilation Air
This heater shall not be installed in a confined space or unusually tight
construction unless provisions are provided for adequate combustion and
ventilation air.
The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a
space whose volume is less than 50 cubic feet per 1,000 Btu per hour
3
per kw) of the aggregate input rating of all appliances installed in
(4.8m
that space and an unconfined space as a space whose volume is not less
than 50 cubic feet per 1,000 Btu per hour (4.8m
3
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.
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 fits the
definition of an unconfined 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 unconfined
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 BF20 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
unconfined space with no requirement to provide additional combustion
and ventilation 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.
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 the heater is installed in a building of unusually tight construction,
adequate air for combustion, ventilation and dilution of flue gases shall
be provided in accordance with ANSI Z223.1/NFPA54.
Clearances (Figure 1)
When facing the front of the appliance the following minimum clearances to combustible construction must be maintained.
Left side 5 inches (127mm). Right side 5 inches (127mm).
Do not install in alcove or closet.
Rear wall 0 inches (0mm). Ceiling 36 inches (914mm).
Minimum vertical clearance from a projection above the appliance
(shelves, window sills, etc.) 36 inches (914mm).
Floor (top surface of carpeting, tile, etc.) 2 inches. (51mm)
Provide adequate clearances around air openings.
Adequate accessibility clearances for purposes of servicing and proper
operation must be provided.

Gas Supply (Figure 4)
Check all local codes for requirements, especially for the size and
type of gas supply line required. On Natural gas lines less than 15'
(4.6m) long, use 1/2" (13mm) pipe; on longer runs, use 3/4"
(19mm)iron pipe or equal. On LP gas lines please consult LP gas
supplier.
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 liquefied 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 flame 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 by the
National Fuel Gas Code that a drip line be installed near the gas inlet.
This should consist of a vertical length of pipe tee connected into the gas
line that is capped on the bottom in which condensation and foreign
particles may collect.

The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of Other
Than All-Metal Construction
The above connectors may be used if acceptable by the authority having
jurisdiction.

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.
High Altitudes
For altitudes/elevations above 2,000 feet (610m), ratings should be
reduced at the rate of 4 percent for each 1,000 (305m) feet above sea
level. Contact the manufacturer or your gas company before changing spud/orifice size.
Piezo Pilot Ignitor Instructions
Depressing the ignitor button completely causes a spark to occur at the
pilot.
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 flame 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.
Keep appliance area clear and free from combustible materials,
gasoline and other flammable vapors and liquids.
Glass Removal, Cleaning and Glass Replacement
1. Remove chrome grill from reflector.
2. Slide glass upward to remove glass from chrome grill.

flames 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.
Oxygen Depletion Sensor Pilot (Figure 9)
When the pilot has a large yellow tip flame, clean the Oxygen Depletion
Sensor as follows:
1. Remove pilot from main burner assembly, see "Appliance Maintenance", Page 6.
2. Apply air pressure through the holes in the pilot indicated by the
arrows in Figure 9. This will blow out foreign materials such as
dust, lint and spider webs.
Figure 9
Warning:
Never use needles, wires, or similar cylindrical objects to
clean the pilot to avoid damaging the calibrated ruby that
controls the gas flow.

Cleaning Main Burner Orifice and Main Burner
1. Turn OFF gas supply to the heater.
2. Turn OFF electric supply to the heater if optional blower, SRB-18T
or SRB-30T is installed in heater.
3. Remove lower louver from casing assembly (2 screws).
4. Remove reflector from casing assembly (2 screws).
5. Inspect interior of casing assembly for accumulation of dust, lint or
spider webs. If necessary, clean interior of casing assembly with a
vacuum cleaner or apply air pressure. Do not damage any components
within casing assembly when you are cleaning.
6. Remove main burner orifice from orifice holder.
7. Apply air pressure through main burner orifice and orifice holder to
remove dust, lint or spider webs.
8. Apply air pressure into main burner to remove dust, lint or spider
webs.
9. As parts are being replaced in reverse order, check for gas leaks at
all gas connections before lower louver is replaced onto casing
assembly.
Proper Pilot Flame (Figure 8)
The correct flame will be blue and will extend beyond the thermocouple.
The flame will surround the thermocouple just below the tip. A slight
yellow flame may occur where the pilot flame and main burner flame
meet.
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 flame
between minimum input and maximum input.
BF-30
The gas control modulates from a minimum input of 8,500 BTU/HR
(2.5 KW/H) (LO setting) to a maximum input of 30,000 BTU/HR
(8.8 KW/H) (HI setting). The hydraulic thermostat bulb which is
located at the casing assembly bottom adjusts the main burner flame
between minimum input and maximum input.
Note: When the hydraulic thermostat bulb is "satisfied" the main
burner flame will shut "OFF" with the pilot flame 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.
Figure 8
R-4973 Page 7
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.
