Owner's Manual • Journeyman
Overview
The heater is equipped with a burner assembly. The
assembly includes an electronic igniter, solenoid
valve, and burner head with nozzle. When the heater
is turned ON, the burner will perform a 45 seconds
pre-purge. The main motor will not start right away.
After the pre-purge, the igniter will spark and fuel
will be delivered through the solenoids to the burner
nozzle. Ignition will occur.
The burner will heat the heat exchanger. Once the
heat exchanger has been heated, a fan switch will
energized the main motor relay and start the main
motor, and blow cool air over the heat exchanger.
The cool air will be heated by passing over the heat
exchanger, with warm, dry air delivered the area to
be heated.
Combustion by-products created during the heating
process will be transferred up a vent stack directly to
the outside, thereby providing only clean, dry air to the
heated area.
When the heater is turned OFF, oil solenoid valve will
be de-energized. The burner motor will continue to
operate for a short time to burner off any leftover fuel.
The main motor will continue to operate to cool down
the heater exchanger. The fan switch will de-energize
the main motor relay, thereby turning the main motor
OFF.
NOTE: Residual heat in the heat exchanger could
cause the fan switch to close and re-energize the
main motor. This is normal operation.
CAUTION
During operation the main motor may start at
any time.
