Installation Instructions and Owner’s Manual

Unvented LP-Gas Vent Free Room Heaters

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.
