 WARNING: Do not allow fans 

to blow directly into the fireplace. 

Avoid any drafts that alter burner 

flame patterns. Ceiling fans can 

create  drafts  that  alter  burner 

flame  patterns.  Altered  burner 

patterns can cause sooting.

Due  to  high  temperatures,  the 

appliance should be located out 

of traffic and away from furniture 

and draperies.

Do not place clothing or other 

flammable  material  on  or  near 

the appliance. Never place any 

objects on the heater.

Heater base assembly becomes 

very  hot  when  running  heater. 

Keep children and adults away 

from hot surface to avoid burns 

or  clothing  ignition.  Heater 

will remain hot for a time after 

shutdown. Allow surface to cool 

before touching.

You  must  operate  this  heater 

with a fireplace screen in place. 

Make  sure  fireplace  screen  is 

closed before running heater.

Keep  the  appliance  area  clear 

and free from combustible ma

-

terials, gasoline and other flam

-

mable vapors and liquids.

1.  This appliance is only for use with the type of 

gas indicated on the rating plate. This appliance 

is not convertible for use with other gases. 

2.  Do not place propane/LP supply tank(s) in-

side any structure. Locate propane/LP supply 

tank(s) outdoors (propane/LP units only).

 WARNING: This product con

-

tains and/or generates chemicals 

known to the State of California 

to cause cancer or birth defects 

or other reproductive harm.

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.

 DANGER: Carbon monoxide 

poisoning may lead to death!

Carbon Monoxide Poisoning:

 Early signs of carbon 

monoxide poisoning resemble the flu, with head

-

aches, 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, people with heart 

or lung disease or anemia, those under the influence 

of alcohol and those at high altitudes.

Natural  and  Propane/LP  Gas:

 Natural and pro-

pane/LP gases are odorless. An odor-making 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.

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.

  WARNING:  Any  change  to 

this  heater  or  its  controls  can 

be dangerous.

  WARNING:  Do  not  use  a 

blower  insert,  heat  exchanger 

insert or other accessory not ap

-

proved for use with this heater.
