INSTALLATION
WIRING DIAGRAM 
A receptacle is provided on the left hand side 
of the unit. 120 Volt AC power must be wired to 
the receptacle and the control module plugged 
in for the unit to operate fully. The front and 
rear burners will operate on low, when the unit 
is running on battery back-up.
(Do not cut the ground terminal off under 
any circumstances.)
AERATION 
ADJUSTMENT
The burner aeration is factory set but may need 
adjusting due to either the local gas supply or 
altitude. Open the air shutter for a blue fl ame or 
close for a more yellow fl ame. 
In order to adjust the aeration, the logs, grate 
and burners will need to be removed to be able 
to access the shutters.
