INSTRUCTIONS

 WARNING:

•  If  fireplace  has  glass  doors, 

never operate this heater with 

glass doors closed. If you op

-

erate heater with doors closed, 

heat  buildup  inside  fireplace 

will cause glass to burst. Make 

sure there are no obstructions 

across openings of fireplace.

•  You must operate this heater 

with a fireplace screen in place. 

Make sure fireplace screen is 

closed before running heater.

NOTICE: During initial operation of 

new heater, burning logs will give 

off a paper-burning smell. Open 

damper or window to vent smell. 

This will only last a few hours.

Note: Homeowners generally prefer to oper-
ate  their  heater  with  the  chimney  damper 
closed. This will put all the heat into the room. 
However, there may be times you will desire 

the full flames of the HI heat setting but will 
find the heat output excessive. You can open 

the chimney damper (if you have one) fully or 
partially to release some of the heat.

  WARNING:  Damper  handle 

will  be  hot  if  heater  has  been 

running.

umn 1.

2.  Make  sure  equipment  shutoff  valve  is 

fully open.

3.  Set switch in the OFF position.

on  automatically  within  one 

minute when the selector switch 

is  in  the  ON  position  after  the 

pilot is lit.

4.  Press in and turn control knob clockwise 

 to the OFF position.

FOR YOUR SAFETY 

READ BEFORE LIGHTING

 WARNING: If you do not fol-

not use any phone in your building.

from a neighbor’s phone. Follow the

the gas control knob. Never use tools. 
If the knob will not push in or turn by 
hand, don’t try to repair it, call a quali

fied service technician or gas supplier. 
Force or attempted repair may result in 
a fire or explosion.

inspect  the  appliance  and  to  replace 
any  part  of  the  control  system  and 
any gas control which has been under 
water.
