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:

Propane/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.

WARNINGS

IMPORTANT

: Read this owner’s manual carefully

and completely before trying to assemble, operate,

or service this heater.  Improper use of this heater

can cause serious injury or death from burns, fire,

explosion, electrical shock, and carbon monoxide

poisoning.

WARNING:

 This appliance is equipped for (natural

or propane) gas. Field conversion is not permited.

WARNING:

 Do not use any accessory not ap-

proved for use with this heater.

WARNING: 

Any change to this heater or its controls

can be dangerous.

Do not place clothing or other flammable

material on or near the appliance.  Never

place any objects on the heater.

Due to high temperatures, heater should be

kept out of traffic and away from furniture and

draperies.

Surface of heater becomes very hot when

running. Keep children and adults away from

hot surfaces to avoid burns or clothing ignition.

Heater will remain hot for a time after shut-

down.  Allow heater surfaces to cool before

handling.

Young children should be carefully supervised

when they are in the same room with heater.

Make sure grille guard is in place before

running heater.  If screen or grille guard is

removed for servicing it must be replaced prior

to operating the heater.

Keep the appliance area clear and free from

combustible materials, gasoline, and other

flammable vapors and liquids.

Every time the hose is connected to unit,

connection must be checked for leaks in one or

more ways: Apply soapy water to connection, look

for bubbles, listen for hiss of escaping gas, feel for

extreme cold, smell for rotten egg odor. Do not use

if leaking!

PRECAUTIONS:

WARNING:

1. 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
