Diagnostic Features
The control board offers a certain level of diagnostics to help in trouble shooting the
stove. The two areas that are diagnosed by sensors in the stove are:
1. Vacuum – Sensed in the Firebox and Ash pan area of the stove.
2. Heat – Proof of Fire sensed in the Exhaust Temperatures of the stove.
3. High Limit – Over Temp situation sensed in the Firebox.
LED light 2 flashing - The number 2
LED light on the Heat advance bar will
flash if the control board senses a loss of
vacuum. The stove shuts down and the
Number 2 LED light starts flashing
approximately 60 seconds after a loss
of vacuum has been sensed. (Fig 16)
LED light 3 flashing - The number 3
LED light on the Heat advance bar will
flash if the control board senses that the
Proof of Fire Switch opens. The stove
shuts down and the Number 3 LED light
starts flashing after the stove cools down
and the fans shut off. Approximately 30
minutes. (Fig 17)
LED light 2 and 3 flashing at the same
time – This will indicate that the High
Limit Switch has tripped and shut the
unit down. Reset the High Limit Switch
before diagnosing the unit. (Fig 18) First
Generation Digital Control Boards do
not have this feature.
