Installation instructions and Owner’s Manual

This appliance may be installed in an aftermarket* permanently manufactured (mobile) home, where not prohibited by
local codes.This appliance is only for use with the type of gas indicated on the rating plate.  This appliance is not
convertible for use with any other gas.

*Aftermarket completion of sale, not for the purpose of resale, from the manufacturer.

2. 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.

3. If heater shuts off, do not relight until you provide

fresh, outside air.  If heater keeps shutting off, it
requires servicing.

4. Turn off and unplug heater and let cool before servic-

ing.  Only a qualified service person should service
and repair heater.

5. Do not run heater:

Where flammable liquids or vapors are used or
stored

During dusty conditions.

6. 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.

7. 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.

8. Operating heater above elevations of 4,500 feet could

cause pilot/ODS to shutdown heater.

9. 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
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.
