WIRING DIAGRAM
This heater does not require a 120V A.C. supply for operation. In case of a power failure, the burner switch and the optional remote control/thermostat will
continue to operate. However, a 120V A.C. power supply is needed for the fan/blower operation.
CAUTION: Label all wires prior
to disconnection when servic-
ing controls. Wiring errors can
cause improper and dangerous
operation.
WARNING: Electrical Grounding Instructions
This appliance is equipped with a three pronged (grounding) plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from
this plug.
Caution: Ensure that the wires do
not touch any hot surfaces and are
away from sharp edges.
