CONTROL BOARD OPERATION
Stove On / Off Button – This button will turn your
stove on or off while in Manual or Automatic mode (see
page 25 for details). The green on / off light at the top
of control board will indicate the on / off status.
Heat Output Button – The heat output button has
three selection settings, Low, Medium and High.
Pressing the button will scroll the red indicator lights
from Low to High. The button controls the pellet feed
and combustion airflow simultaneously. The control
board is preset to provide the optimum ratio of fuel and
air at each setting. Settings can be changed at any
time but will only take affect after the start-up cycle is
complete. Each press of the Heat Button will increase
the heat output, and will scroll to the lowest setting af-
ter reaching the maximum setting.
Blower – The blower button operates the room air
blower. This will change the flow of hot air into the
room. Three choices are available Low, Medium, and
High. When the Blower Button is pressed the yellow
indicator light will scroll to Low, Medium, or High.
When running your stove on high heat output,
the control board will not allow you to select
the low blower speed. This is a safety precau-
tion to protect against overheating. Blower set-
tings can be changed at any time, but will only
take affect after the start-up cycle is complete.
Fault Mode – The control system automatically moni-
tors the flame using a photoeye. If the stove runs out of
pellets the control board automatically goes into a
“fault” status. The control board will initiate the shut
down cycle and safely shut down the stove leaving it in
the “fault” mode. The on / off indicator light near the top
of the control board will flash rapidly when in this
mode. After refilling the hopper with pellets, press the
Start Button. If a thermostat is not being used the
stove will go into the start-up cycle. If a thermostat is being
used the stove will go into the start-up cycle if the thermo-
stat is in the demand mode. If the thermostat is in the
stand-by mode when the fault is cleared, the stove will re-
main in the stand-by mode until it closes again.
NOTE – If the fuel feed trim or combustion air trim
needs to be adjusted, contact an authorized Lennox
Hearth Products Technician to calibrate internal soft-
ware. It is recommended that the damper be used to
fine-tune your stove to your particular fuel and installa-
tion configuration (see Damper Adjustment on page 12
and Damper Adjustment Guideline on page 26).
