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.

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.

off the heater if there is not enough fresh air.
IGNITION SYSTEM
PIEZO: BF10LP/ IR10LP – The heater is equipped with
a piezo manual ignitor. This system requires no matches, batteries, or other source to light heater.
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 or the International
Fuel Gas Codes.
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.
FRESH AIR FOR COMBUSTION AND
VENTILATION
WARNING: If the area in which the heater may be
operated does not meet the required volume for
indoor combustion air, combustion and ventilation
air shall be provided by one of the methods
described in the National Fuel Gas Code, ANSI
Z223.1.NFPA 54, the International Fuel Gas
Code, or applicable Local Codes.
This heater shall not be installed in a room or space
unless the required volume of indoor combustion air
is provided by the method described in the National
Fuel Gas Code, ANSIZ223.1.NFPA 54, the International Fuel Gas Code, or applicable local codes.

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 figure 2). You can also remove door into adjoin-
ing room (see option3, fig 2). Follow the National Fuel
Gas Code NFPA 54/ ANSI Z223.1, the International
Fuel Gas Codes or applicable local codes, Air for
Combustion and Ventilation for required size of ventilation grills or ducts.

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
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 3
through 5.
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 primary 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.
