CARE AND OPERATION

CONTROL BOARD OPERATION

Stove On / Off Button – This button will turn your stove on or off while in Manual or Automatic mode (see page 19 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. NOTE: 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 precaution to protect against overheating. Blower settings 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 thermostat is in the demand mode. If the thermo-

stat is in the stand-by mode when the fault is cleared, the stove will remain 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 8 and Damper Adjustment Guideline on page 20).
