PRECAUTIONS:
1. BF-10 LP and IR-10LP may be installed in a bedroom, but not a bathroom, or any place where a
strong wind would shut down the appliance.
2. This heater needs outside ventilation air to run
properly. The Oxygen Depletion Sensor (ODS) safety
shutoff system shuts down the heater if not enough
fresh air is available. See Fresh Air for Combustion
and Ventilation, page 3.
3. Keep all air openings in heater clear, free of debris
or any blockage. This will insure that enough air for
proper combustion enters the heater.
4. If heater shuts off, do not relight until you provide
fresh, outside air. If heater keeps shutting off, it requires servicing.
5. Turn off and let cool before servicing. Only a qualied service person should service and repair heater.
6. Do not run heater:
• Where ammable liquids or vapors are used or stored
• During dusty conditions.
7. Before using furniture polish, wax, carpet cleaner or
similar products, turn heater off. If heated the vapors
from these products may create a white powder
residue within burner box or on adjacent walls or
furniture.
8. Do not use heater if any part has been underwater.
Immediately call a qualied service technician to in-
spect the room heater and to replace any part of the
control system and any gas control which has been
underwater.
9. Operating heater above elevations of 4,500 feet
could cause pilot/ODS to shutdown heater.
10.Always run heater with control knob in a locked position. Never set control knob between locked positions. Poor combustion and higher levels of carbon
monoxide may result if control knob is left between
locked positions.
DANGER: Carbon monoxide poisoning may lead to
death.
Carbon Monoxide Poisoning:
Early signs of carbon monoxide poisoning resemble the
u, with headaches, dizziness, or nausea. If you have
these signs, the heater may not be working properly.
Get fresh air at once! Have heater serviced. Some
people are more affected by carbon monoxide than others. These include pregnant women, persons with heart
or lung disease or anemia, those under the inuence of
alcohol, and those at high altitudes.
Propane/LP Gas:
Propoane/LP gas is odorless. An odor making agent is
added to propane/LP gas. The odor helps you detect
a Propane/LP gas leak. However the odor added to
propane/LP 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
safe and proper operation of this heater.

FRESH AIR FOR COMBUSTION AND
VENTILATION
WARNING: This heater shall not be installed in a
conned space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following instruc-
tions to insure proper fresh air for this and other
fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas
Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation. All spaces in homes fall into
one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
This heater must not be installed in a conned space or
unusually tight construction unless provisions are provided for adequate combustion and ventilation air. The
information on pages 3 through 5 will help you classify
your space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you
must provide additional fresh air. See Ventilation Air
from Outdoors, page 5.
Unusually tight construction is dened as construction
where:
a. Walls and ceilings exposed to the outside atmo-
sphere have a continuous water vapor retarder with
a rating of one perm (6 x 10
less with openings gasketed or sealed and
-11
kg per pa-sec-m2) or
b. Whether stripping has been added on openable win-
dows and doors, and
c. Caulking or sealants are applied to areas such as
joints around windows and door frames, between
wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at
other openings.
If you home does not meet all of the three criteria
above, see Determing the Type of Heater Location
Space, below.
Conned Space and Unconned Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1
denes a conned space as a space whose volume is
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, and an unconned 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 fur-
nished with doors, are considered a part of the uncon-
ned space.
*Adjoining rooms are communication only if there
are doorless passageways or ventilation grills between them.
DETERMINING THE TYPE OF HEATER
LOCATION SPACE:
Use this method to determine if you have a conned or
unconned space.
Note: the space includes the room in which you
install heater plus any adjoining rooms with doorless passageways or ventilation grills between the
rooms.
1. Find the volume of the space by multiplying room
length x width x height.
Example: Space size 18ft (length) x 18ft. (width) x 8ft.
(height) = 2592
If additional ventilation to adjoining room is supplied
with grills or openings, add the volume of these rooms
to the total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum Btu/hr the space can support.
Example: 2592 cu.ft. (volume of space) / 50 cu.ft. =
51.8 or 51,800 (maximum Btu/hr the space
can support)
WARNING: If the area in which the heater may be
operated is smaller than dened as an unconned
space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by the methods described in the National
Fuel Gas Code, NFPA 54/ ANSI Z223.1, Section
5.3 or applicable local codes.
3. Add the Btu/hr of all the fuel-burning appliances
in the space such as, Vent–free heater, Gas water
Unvented Liquid Propane Fired Room Heater
Installation Instructions and Owner’s Manual
4
heater, Gas furnace, Vented gas heater, Gas replace logs, and Other gas appliances*
*Do not include direct-vent gas appliances. Directvent draws combustion air from the outdoors and
vents to the outdoors.
Example:
Gas water heater 40,000 Btu/hr
Vent Free Heater + 20,000 Btu/hr
Total =60,000 Btu/hr
4. Compare the maximum Btu/hr the space can support
with the actual amount of Btu/hr used.
Example: 51,800 Btu/hr (maximum Btu/hr the
space can support)
60,000 Btu/hr (Actual amount of Btu/hr used)
The space in the above example is a conned
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. Rework worksheet, and the space of an adjoining
room. If the extra space provides an unconned
space, remove door to adjoining room or add ventilation grills between the rooms. See Ventilation Air
From Inside Building (Fig. 2)
B. Vent room directly to the outdoors. See Ventilation
Air From Outdoors (Fig. 3).
C. Install a lower Btu/hr heater if lower Btu/hr size
makes room unconned.
If actual Btu/hr used is less than the maximum Btu/
hr the space can support, the space is an uncon-
ned space. You will need no additional fresh air
ventilation.
VENTILATION AIR
Ventilation from Inside Building
This fresh air would come from an adjoining unconned
space. When ventilation to an adjoining unconned
space, you must provide two permanent openings: one
within 12” of the ceiling and one within 12” of the oor
on the wall connecting the two spaces (see options 1
& 2 of gure 2). You can also remove door into adjoining room (see option3, g 2). Follow the National Fuel
Gas Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for
Combustion and Ventilation for required size of ventilation grills or ducts.
WARNING: Rework worksheet, adding the space
of the adjoining unconned space. The combined
space must have enough fresh air to supply all ap-
pliance in both spaces.
Ventilation from Outdoors
If necessary provide extra fresh air by using ventilation grills or ducts. Connect these items directly to the
outdoors or spaces open to the outdoors. These include

*IMPORTANT: Do not provide openings for inlet or
outlet into attic. If attic has a thermostat-controlled
power vent, heated air entering the attic will activate
the power vent.
IMPORTANT: Vent-free heaters add moisture to
the air. Although this is benecial, installing heater
in rooms without enough ventilation air may cause
mildew to form from too much moisture. See Fresh
Air for Combustion and Ventilation, pages 3
through 5.

CONNECTING TO GAS SUPPLY
WARNING: A qualied service person must con-
nect heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection to the
pressure regulator. Use of oor mounting feet will
require you to use a 3/8 NPT street elbow to make
gas connection.
CAUTION: Never connect heater directly to the
Propane supply. This heater requires an external
regulator (not supplied). Install the external regulator
between the heater and Propane/LP supply.
The installer must supply an external regulator.
The external regulator will reduce the incoming gas
pressure to between 11 and 14 inches of water. If
you do not reduce incoming gas pressure heater
regulator damage could occur. Install external regulator with the vent pointing down. Pointing the vent
down protects it from freezing rain or sleet.
CAUTION: Use only new black iron or steel pipe.
Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of larger
enough diameter to allow proper gas volume to heater.
If pipe is too small, undue loss of pressure will occur.
Installation must include an equipment shutoff valve,
union and plugged 1/8” NPT tap. Locate NPT tap within
reach of test gauge hookup. NPT tap must be upstream
from heater (see gure 12).
*A CSA/AGA certied equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certied equipment
shutoff valve from your dealer.
IMPORTANT: Install an equipment shutoff valve in an
accessible location. The equipment shutoff valve is for
turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess
sealant in pipe could result in clogged heater fuel train.
CAUTION: Use pipe joint sealant that is resistant to
LP-Gas.
Install sediment trap in supply line as shown in gure
12. Locate sediment trap where it is within reach for
cleaning. A sediment trap traps moisture and contaminants. This keeps them from going into heater. If
sediment trap is not installed or is installed improperly,
heater may not run correctly.
IMPORTANT: Hold pressure regulator with wrench
when connecting it to gas piping and/or ttings.

PILOT FLAME PATTERN
Figure 21 show a correct pilot ame pattern. Figure 22
shows an incorrect pilot ame pattern. The incorrect
pilot ame pattern is not touching thermocouple. This
will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot ame
pattern is incorrect, as shown in Figure 22:
• Turn heater off (see To Turn OFF Gas to Appli-
ance, page 10.
• See Troubleshooting, pages 12-13.
CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before
servicing.
CAUTION: You must keep control areas, burner and
circulation air passageways of heater clean. Inspect
these areas of heater before use. Have the heater
inspected yearly by a qualied service person. Heater
may need more frequent cleaning due to excess lent
from carpeting, bedding material, pet hair, etc.
Make sure grille guard is in place before running
heater. If screen or grille guard is removed for servicing
it 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.
CLEANING ODS/PILOT AND BURNER
• Use as vacuum cleaner, pressurized air or
small soft bristled brush to clean.
CLEANING BURNER PILOT AIR HOLE INLET
We recommend that you clean the unit every 2,500
hours of operation or every three months. We also
recommend that you keep the burner tube and pilot
assembly clean and free of dust and dirt. To clean these
parts we recommend using compressed air no greater
than 30 psig.
This can be done by using a vacuum cleaner in the
blow position, using compressed air in a can, please
follow the directions on the can. If you don’t follow
directions on the can you could damage the burner or
pilot assembly. In addition, the directions that follow
should also be followed.
1. Shut off the unit, including the pilot. Allow the
unit to cool for at least thirty minutes.
2. Inspect burner and pilot for dust and dirt.
Note: Your heater may have either pilot assembly.

Correct pilot position.
Incorrect pilot position.
3. Blow air through the port/slots and holes in the
burner.
A yellow tip on the pilot ame indicates dust and dirt in
the pilot assembly. To clean the pilot assembly nd the
small pilot air inlet hole about two inches from where
the pilot ame comes out of the pilot assembly (see
gure 25). With the unit off, lightly blow air through the
air inlet hole. You may blow through a drinking straw if
compressed air is not available.
