CAUTION: Never connect heater directly to the
Propane supply. This heater requires an external
regulator (not supplied). Install the external regula-
tor 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 pres-
sure heater regulator damage could occur. Install
external regulator with the vent pointing down.
Pointing the vent down protects it from freezing
rain or sleet.

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 po-
sition. Never set control knob between locked posi-
tions. 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 oth-
ers. These include pregnant women, persons with heart
or lung disease or anemia, those under the inuence 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 warn-
ings. Keep this manual for reference. It is your guide to
safe and proper operation of this heater.
PRECAUTIONS:
1. BF-20 LPT, BF-30 LPT, IR-20 LPT and IR-30 LPT
may not be installed in a bedroom or 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, pages 5 through 6.
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 unplug heater and let cool before
servicing. Only a qualied 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 qualied service technician to
inspect the room heater and to replace any part of
the control system and any gas control which has
been underwater.

where you bought heater.
FRESH AIR FOR COMBUSTION AND
VENTILATION
WARNING: This heater shall not be installed in a
conned space or unusually tight construction un-
less provisions are provided for adequate combus-
tion 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 Com-
bustion and Ventilation. All spaces in homes fall into
one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
This heater must not be installed in a conned space or
unusually tight construction unless provisions are pro-
vided for adequate combustion and ventilation air. The
information on pages 4 through 6 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 6.
Unusually tight construction is dened 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 10-11 kg per pa-sec-m2) or
less with openings gasketed or sealed and
b. Weather 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 penetra-
tions for plumbing, electrical, and gas lines, and at
other openings.
If your home does not meet all of the three criteria
above, see Determing the Type of Heater Location
Space, page 5.
Conned Space and Unconned Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1
denes a conned 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 unconned 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.

Unvented LP-Gas Vent Free Room Heaters
*Adjoining rooms are communication only if there
are doorless passageways or ventilation grills be-
tween them.
DETERMINING THE TYPE OF HEATER
LOCATION SPACE:
Use this method to determine if you have a conned or
unconned 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 deter-
mine 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 dened as an unconned
space or if the building is of unusually tight con-
struction, provide adequate combustion and ventila-
tion 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
heater, Gas furnace, Vented gas heater, Gas re-
place logs, and Other gas appliances*
*Do not include direct-vent gas appliances. Direct-
vent 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 conned
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 unconned
space, remove door to adjoining room or add venti-
lation grills between the rooms. See Ventilation Air
From Inside Building (Figure 2).
B. Vent room directly to the outdoors. See Ventilation
Air From Outdoors (Figure 3).
C. Install a lower Btu/hr heater if lower Btu/hr size
makes room unconned.
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 unconned
space. When ventilation to an adjoining unconned
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 g. 2). You can also remove door into adjoin-
ing 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 ventila-
tion grills or ducts.

LOCATING HEATER
This heater is designed to be mounted on the wall. The
heater can also be located on a non-combustible oor,
away from a wall by using the oor mounting stands in-
cluded with the heater. If installed on combustible oor-
ing such as carpeting, tile or other combustible material
other than wood ooring, the heater must be placed on
a wood panel the full width and depth of the appliance.
For convenience and efciency, install the heater:
• Where there is easy access for operation,
inspection, and service
• In the coldest part of the room.
• If planning to use fan, locate heater near an
electrical outlet.
CAUTION: If you install the heater in a home garage:
Heater pilot and burner must be at least 18 inches
above oor . Locate heater where moving vehicle will
not hit it.
CAUTION: This heater creates warm air currents.
These currents move heat to wall surfaces next to
heater. Installing heater next to vinyl or cloth wall
covering or operating heater where impurities (such
as tobacco smoke, aromatic candles, cleaning uids,
oil or kerosene lamps, etc.) are present in the air may
discolor walls.
WARNING: Never install the heater:
• In a bedroom (IR20LPT, IR30LPT, BF20LPT or
BF30LPT)
• In a recreational vehicle ·.
• Where curtains, furniture, clothing, or other
ammable objects are less than 36 inches from
the front, top, or sides of the heater.
• As a replace insert
• In high-trafc areas
• In windy or drafty areas
WARNING: Heater must be mounted to maintain
the minimum clearances shown in Figure 4. If pos-
sible, provide greater clearances from the oor, ceil-
ing, and joining walls.
WARNING: Rework worksheet, adding the space
of the adjoining unconned 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 ventila-
tion grills or ducts. Connect these items directly to the
outdoors or spaces open to the outdoors. These include
attics* and crawl spaces. Follow the National Fuel Gas
Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for Com-
bustion and Ventilation for required size of ventilation
grills or ducts.
*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 benecial, 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 5 through
6.
INSTALLATION
NOTICE: This heater is intended for the use as supple-
mental heat. Use this heater along with your primary
heating system. Do not install this heater as your pri-
mary heat source. If you have a central heating system,
you may run system’s circulating blower while using
heater. This will help circulate the heat throughout the
house. In the event of a power outage, you can use this
heater as your primary heat source for the duration of
the outage.
WARNING: A qualied service person must install
heater. Follow all local codes.

Unvented LP-Gas Vent Free Room Heaters
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 ex-
ternal 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 dam-
age 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 cer-
tain 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).
Figure 12
*A CSA/AGA certied equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certied 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.

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 con-
taminants. 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.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for
leaks after installing or servicing. Correct all leaks

9. To select the desired heat level, turn the
temperature setting knob counterclockwise to
between 1 & 5.
THERMOSTAT CONTROL OPERATION
FOR IR20LPT / IR30LPT: The thermostatic control
used simply turns on and off the burner.
FOR BF20LPT / BF30LPT: The thermostatic control
used modulates the ame size as the temperature gets
closer to set point, then it turns off the burner upon
reaching temperature.
The burner will cycle back on when room temperature
drops below the set temperature. The control knob can
be set to any heat level between 1 and 5. Selecting the
HI setting will cause the burner to remain on.
TO TURN OFF GAS TO APPLIANCE
SHUTTING OFF HEATER
1. Turn control knob clockwise to the OFF posi-
tion.
2. Turn off all electrical power to the appliance if
servicing is to be preformed.
3. Turn off equipment shutoff valve.
SHUTTING OFF BURNER ONLY (PILOT STAYS LIT)
1. Turn control knob clockwise to the PILOT/IGN
position.
INSPECTING BURNER
Check pilot ame pattern and burner ame pattern
often.
PILOT FLAME PATTERN
Figure 21 shows 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 thermo-
couple 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, above.
• See Troubleshooting, pages 14-15.
