Mt. Vernon Pellet Stove (AE)
1. Start-Up Cycle
During this cycle:
•
Igniter turns on for 90 seconds to heat up the air in the
firepot
• C
ombustion blower starts
• V
acuum switch comes on
• Feed motor turns on adding fuel to the firepot and the
appliance waits for the fire to start
The duration of start-up depends on the type and quality
of fuel used. It is normal to see some smoke during the
ignition process as moisture evaporates and the fuel lights.
The smoke will stop once the fire starts.
K. Ignition Cycles
The appliance engine is controlled by the digital thermostat
wall control. The digital display on the wall control will tell
you what your appliance is doing in the upper left corner
