IMPORTANT SAFETY INFORMATION 

 

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. 
Only a qualified installer, service agent, or local 
gas supplier may install and service this product. 

 

WARNING:

 

Do not store or use gasoline 

or other flammable vapors and liquids in the 
vicinity of this or any other appliance. 

 

CARBON MONOXIDE POISONING:

 Early signs 

of carbon monoxide poisoning resemble the flu 
with headache, dizziness and/or nausea. If you 
have these signs, heater may not be working 
properly. Get fresh air at once! Have heater 
serviced. Some people - pregnant women, 
persons with heart or lung disease, anemia, 
those under the influence of alcohol, those at 
high altitude - are more affected by carbon 
monoxide than others. 

 

Natural and Propane /LP Gas:

 

Natural and 

Propane/LP gas are odorless. An odor-producing 
agent is added to the gas. The odor helps you 
detect a gas leak. However, the odor added to 
the gas can fade. Gas may be present even 
though no odor exists. 

 

WARNING: 

Any change to this heater or its 

controls can be dangerous. 

 

WARNING: 

Do not use any accessories 

not approved for use with this heater.

WARNING:

 

Keep the appliance area clear 

and free from combustible materials, gasoline, 
and other flammable vapors and liquids. 

WARNING: 

Due to high temperatures, the 

appliance should be located out of traffic and 
away from furniture and draperies. 

 

WARNING: 

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 
shutoff. Allow surfaces to cool before touching. 

 

WARNING: 

Do not place clothing or other 

flammable material on or near the appliance. 
Never place any objects in the heater. 

 

WARNING: 

Failure to keep the primary air 

opening(s) of the burner(s) clean may result in 
sooting and property damage.

 

 

WARNING:

 

Do not allow fans to blow 

directly towards the heater. Avoid any drafts that 
alter burner flame patterns. 

 
WARNING:

 

Do not use a blower insert, 

heat exchanger inserts or other accessory not 
approved for use with this heater.

accordance with these diagrams or failure to use 
only  parts  specifically  approve  with  this  heater

time are prohibited. The ignition button on the 
dual fuel models shall not be depressed while the 
heater is in operation.
