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.

B.  BEFORE LIGHTING smell all around the 

appliance area for gas. Be sure to smell next 

to the floor because some gas is heavier than 

air and will settle on the floor.

  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.

•  Immediately  call  your  gas  supplier 

from 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.

This will only last a few hours. 

 CAUTION: A mild gas flash 

within  10  seconds  is  normal 

during shutdown of this heater. 

Remain clear of the hearth area 

for the entire shutdown process

safety information, column 1. If you don’t 

smell gas, go to the next step.

5.  Make sure ON/OFF switch is in "–" (ON)
