Heater assembly is now ready for operation. Make sure heater setup has not been changed, ducts and
pipes are properly positioned, and heated air is directed in a safe manner. See applicable setup
instructions in this section if in doubt as to existing setup.
If heat is desired, place heater ON/OFF switch in the ON position and verify that HEATER ON/ON-HOLD
light is lit.
REFUELING WITH A DIFFERENT FUEL
When changing fuel types, all existing fuel must be drained from the fuel supply system as detailed in the
section to follow. Also, the heater must be operated through a minimum of one charging cycle to work the
new fuel through the system. A charging cycle is performed after the system has been refueled with a
different fuel.
A charging cycle starts when the heater ON/OFF switch (1) is moved to the ON position and ends when
the BATTERY CHARGED light (2) comes on. This must be accomplished to make sure that all the old
fuel is burned during heater operation and the only fuel remaining in the heater fuel system is the new fuel
type.
