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 with a piezo ignitor. When lightning 

the pilot, follow these instructions exactly.

B.  BEFORE LIGHTING smell all around the 

appliance area for gas. Be sure to smell next

• Do not touch any electric switch; do not 

use any phone in your building.

a  neighborʼs  phone.  Follow  the  gas 

supplierʼs instructions.

the fire department.

C.  Use only your hand to push in or turn gas 

control knob. Never use tools. If the knob 

will not push in or turn by hand, do not try 

to repair it, call a qualified technician. Force 

or attempted repair may result in a fire.

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.
