OPERATINg APPLIANCE

FOR YOUR SAFETY 

READ BEFORE LIGHTING

 WARNING: Keep flue open 

when operating unit.

 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.

B.  BEFORE LIGHTING smell all around the 

appliance area for gas. Be sure to smell next

  WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do not use 

any phone in your building.

a  neighbor’s  phone.  Follow  the  gas 

supplier’s instructions.

• If you cannot reach your gas supplier, 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 qualified service tech

-

nician 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 part of the 

control system and any gas control which 

has been under water.

LIGHTING 

 INSTRUCTIONS

NOTICE:  During  initial  opera-

tion of new appliance, metallic 

components may emit an odor as 

paint and assembly compounds 

are  heated  and  cure.  Be  sure 

to provide adequate fresh air if 

odors are detected.

  WARNING:  Damper  handle 

will be hot if appliance has been 

running.

 CAUTION: A mild gas flash 

may occur within 10 seconds of 

normal shutdown of this appli-

ance. Remain clear of the hearth 

area for the entire shutdown pro-

cess to avoid possible injury.

1.  STOP!  Read  the  safety  information  in 

column 1.

2.  Make sure equipment shutoff valve is fully 

open.

3.  Set selector switch in the OFF position. 

4.  Press in and turn control knob clockwise  

 to the OFF position (see Figure 11,
