 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

-

ning heater. 

NOTICE: During initial operation 

of new heater, burning logs will 

give off a paper-burning smell. 

Orange flame will also be pres

-

ent. Open damper or window to 

vent smell. This will only last a 

few hours. 

Note: Home owners 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.

1.  STOP!  Read  the  safety  information  in 

column 1.

2.  Make sure equipment shutoff valve is fully 

open.

FOR YOUR SAFETY 

READ BEFORE LIGHTING

 WARNING: If you do not fol-

low  these  instructions  exactly, 

a  fire  or  explosion  may  result 

causing property damage, per

-

sonal injury or loss of life.

A.  This appliance has a pilot which must 

be  lighted  by  hand.  When  lighting 
the  pilot,  follow  these  instructions 
exactly.

the appliance area for gas. Be sure to

on the floor.

• Do not touch any electric switch; do 

not use any phone in your building.

from a neighbor’s phone. Follow the 
gas supplier’s instructions.

call the fire department.

C.  Use only your hand to push in or turn 

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.

D.  Do not use this appliance if any part 

has  been  under  water.  Immediately 
call  a  qualified  service  technician  to 
inspect  the  appliance  and  to  replace

any gas control which has been under 
water.
