Journeyman Ductable Dual Fuel Indirect-Fired Heater
Owner's Manual • Journeyman
Overview
The heater is equipped with a burner assembly. The
assembly includes an electronic igniter, solenoid
valves, and burner head with orifice. When the heater
is turned ON, the igniter will spark, with gas delivered
through the solenoid to the burner orifice. Ignition will
occur.
The burner will heat the heat exchanger. The main
motor will not start right away. Once the heat
exchanger has been heated, a fan switch will
energize 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, the solenoid valve
will close cutting off gas to the burner. The blower
motor will not stop right away. A fan switch will
continue to run the main motor for a period of time
to allow the heat exchanger to cool down. After this
time frame has elapsed, the fan switch will disconnect
power to the main motor, thereby shutting the main
motor down completely.
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.
