Start-up Sequence of Events

CARE AND OPERATION

Note: The control board is equipped with an internal memory which will recall the last setting and mode the stove was in prior to loss of power. Because we individually check each stove prior to packaging, one of the two scenarios will appear when you first plug in your stove.

1). The Green LED at the top of the control board will illu- minate and the blowers will be running. This is a stan- dard cool down mode and will last no longer than five minutes. This happens during testing when the stove is turned off (which initiates cool down mode) and then is unplugged.

2). The Green LED at the top will illuminate and the red and yellow LED’s will illuminate on the control board, indicating that the stove is in the run mode. This hap- pens during testing if the stove is unplugged without first turning the control board off (the control board re- members its last setting, which was the run mode).

If your stove follows that described in number 2 above, simply press the ON / OFF button once to turn the stove off, this will initiate the cool down mode. The stove can be restarted at any time during the cool down mode by press- ing the ON / OFF button once.
