PRECAUTIONS:
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.­
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 qualified service person should
service and repair heater.
6. Do not run heater:
Carbon Monoxide Poisoning:
Early signs of carbon monoxide poisoning resemble the
flu, 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 influence 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.
• Where flammable 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 qualified service technician to
inspect the room heater and to replace any part of
the control system and any gas control which has
been underwater.

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 classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
This heater must not be installed in a confined space or
unusually tight construction unless provisions are provided for adequate combustion and ventilation air. The
information on pages 4 through 6 will help you classify
your space and provide adequate ventilation.

SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensor (ODS) safety shut off system. The ODS/pilot shuts
off the heater if there is not enough fresh air.
IGNITION SYSTEM
– The heater is equipped with an electronic manual ignitor. This system requires no matches, or other source
to light heater, but does require one AA battery to operate ignitor. (AA Battery included).
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 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 (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 windows 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 your home does not meet all of the three criteria
above, see Determing the Type of Heater Location
Space, page 5.
To install or replace battery unscrew the ignitor cap
(red button), insert battery positive (+) terminal up
and replace cap.
(AA Battery included)
THERMOSTATIC CONTROL
These heaters have a control valve with a thermostat
sensing bulb. This results in the greatest heater comfort
and may result in lower bills.
These heaters also include an electrical blower. The
blower switch has three positions: MANUAL, OFF and
AUTO. In AUTO, the blower will turn on and off as the
heater cycles on and off. On MANUAL, the blower will run
continuously. To turn blower off, use the OFF position.
LOCAL CODES
Install and use heater with care.
Installation must conform to local codes or in the absences of local codes, use the latest edition of National
Fuel Gas Code ANSI Z223.1/NFPA 54.
Confined Space and Unconfined Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1
defines a confined 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 unconfined 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 furnished with doors, are considered a part of the unconfined space.
UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied to
heater for shipment.
3. Check heater for any shipping damage. If
heater is damaged, promptly inform dealer
where you bought heater.

Installation Instructions and Owner’s Manual
*Adjoining rooms are communication only if there
are doorless passageways or ventilation grills between them.
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 unconfined.
If actual Btu/hr used is less than the maximum Btu/
hr the space can support, the space is an unconfined space. You will need no additional fresh air
ventilation.
DETERMINING THE TYPE OF HEATER
LOCATION SPACE:
Use this method to determine if you have a confined or
unconfined 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 defined as an unconfined
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
heater, Gas furnace, Vented gas heater, Gas fireplace 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 confined
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 unconfined
space, remove door to adjoining room or add ventilation grills between the rooms. See Ventilation Air
Unvented LP-Gas Vent Free Room Heaters
VENTILATION AIR
Ventilation from Inside Building
This fresh air would come from an adjoining unconfined
space. When ventilation to an adjoining unconfined
space, you must provide two permanent openings: one
within 12” of the ceiling and one within 12” of the floor
on the wall connecting the two spaces (see options 1
& 2 of fig. 2). You can also remove door into adjoining room (see option3, fig 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.

space must have enough fresh air to supply all appliance in both spaces.­
LOCATING HEATER
Ventilation from Outdoors
This heater is designed to be mounted on the wall. The
heater can also be located on a non-combustible floor,
away from a wall by using the floor mounting stands included with the heater. If installed on combustible flooring such as carpeting, tile or other combustible material
other than wood flooring, the heater must be placed on
a wood panel the full width and depth of the appliance.
For convenience and efficiency, install the heater:
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
attics* and crawl spaces. 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.
*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 beneficial, 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 Instructions and Owner’s Manual
WARNING: This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection to the
pressure regulator. Use of floor mounting feet will
require you to use a 3/8 NPT street elbow to make
gas connection.­
CAUTION: Use pipe joint sealant that is resistant to
LP-Gas.­
Install sediment trap in supply line as shown in figure
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 fittings.
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.­
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for
leaks after installing or servicing. Correct all leaks
at once.­
WARNING: Never use an open flame to check for
a gas leak. Apply a mixture of liquid soap and water
to all joints. Bubbles forming show a leak. Correct
all leaks at once.­
PRESSURE TESTING GAS SUPPLY PIPING
SYSTEM
Test pressure in Excess of ½ psig (3.5kPa)
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 figure 12).
1. Disconnect appliance with its appliance main
gas valve (control valve) and equipment shutoff
valve from gas supply piping system. Pressures
in excess of ½ psig will damage heater regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either using
compressed air or opening main gas valve on
or near gas meter.
4. Check all connections and joints in gas supply
piping system. Apply mixture of liquid soap and
water to gas joints. Bubbles forming show a
leak.
5. Correct all leaks at once.

Force or attempted repair may result in a fire or
explosion.
D. Do not use this appliance if any part has been
underwater. Immediately call a qualified service
technician to inspect the appliance and to replace any part of the control system which has
been underwater.
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 flame 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.
LIGHTING INSTRUCTIONS
1. STOP! Read the all safety information included
with and on the side of heater.
2. Make sure the equipment shutoff valve is fully
open.
3. Push in gas control knob and slightly turn clockwise to the OFF position (see figure 19).
4. Wait five (5) minutes. Then smell for gas including near the floor. If you smell gas, STOP! Follow “B” in the safety information above. If you
do not smell gas, go to the next step.
5. Push in and turn control knob counterclockwise
to PILOT. Press in control knob for five (5) seconds.
Note: The first time that the heater is operated after
connecting the gas supply, the control knob should
be depressed for about 30 seconds. This will allow
air to bleed from the gas system. This may take
longer in some installations

PILOT FLAME PATTERN
Control Knob
Figure 21 shows a correct pilot flame pattern. Figure
22 shows an incorrect pilot flame pattern. The incorrect
pilot flame pattern is not touching thermocouple. This
will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame
pattern is incorrect, as shown in Figure 22:
• Turn heater off (see To Turn OFF Gas to Appliance, above.
Figure 19.
6. With control knob pressed in, push down and
release the ignition button. This will light pilot. If
needed keep pressing igniter button until pilot
