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

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.)

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.

LP Front Burner 1/4"

CAUTION: Label all wires prior to disconnection
when servicing controls. Wiring errors can
cause improper and dangerous operation.
Caution: Ensure that the wires do not touch any
hot surfaces and are away from sharp edges.
CAUTION: Carbon will be produced if air shutter
is tightly closed.
Note: Any damage due to carboning
resulting from improperly setting
the aeration controls is NOT covered
under warranty.
