FOR YOUR SAFETY

READ BEFORE LIGHTING

DO NOT CONNECT 110 VAC TO 
THE CONTROL VALVE.

Improper installation, adjustment, al-
teration, service or maintenance can 
cause injury or property damage. Re-
fer to the owner’s information manual 
provided with this appliance.

This appliance needs fresh air for 
safe operation and must be installed 
so there are provisions for adequate 
combustion and ventilation air.

If not installed, operated, and main-
tained in accordance with the man-
ufacturer’s instructions, this product 
could expose you to substances in fuel 
or fuel combustion which are known to 
the State of California to cause can-
cer, birth defects, or other reproduc-
tive harm.

Keep burner and control compartment 
clean. See installation and operating 
instructions accompanying appliance.

CAUTION:

Hot while in operation. Do not touch. 
Keep children, clothing, furniture, gaso-
line and other liquids having fl ammable 
vapors away.

Do not operate the appliance with 
panel(s) removed, cracked or broken. 
Replacement of the panel(s) should be 
done by a licensed or qualifi ed service

lighting the pilot, follow these 
instructions exactly.

B.

do not use any phone in your 
building.

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 qualifi ed service 
technician. Force or attempted 
repair may result in a fi re or explo-
sion.

D.

 Do not use this appliance if any 

part has been under water. Im-
mediately call a qualifi ed service 
technician to inspect the appliance 
and to replace any part of the
