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  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  af-
fected by carbon monoxide than others. These 

include pregnant women, people with heart or 
lung disease or anemia, those under the influ

-

ence of alcohol and those at high altitudes.

Natural and Propane/LP Gas: 

Natural and 

propane/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 

warnings. 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 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.

  WARNING:  Do  not  use  a 

blower  insert,  heat  exchanger 

insert or other accessory not ap-

proved for use with this heater.

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.

Carefully supervise young chil-

dren when they are in the room 

with heater.

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) 

inside any structure. Locate propane/LP
