These conditions fall into 2 categories:
a.
Heat related issues.
b.
Vacuum related issues.
The Diagnostic Lights flash as follows:
1.
The
Proof of Fire
switch. This switch will sense the temperature of the Exhaust
rising during start up. If the Exhaust temperature does not reach 110 degrees F, or
if, during use, the temperature drops below 110 degrees F, the Insert will go into
“Internal Alarm”
and the Auger will quit feeding fuel. Once the Insert
completes the safety shutdown, the #3 LED will start blinking.

2.
The
High Limit
switch. This sensor will sense if the unit reaches temperatures
that are too high for normal operation. If this happens the Auger will quit feeding
and the #4 LED light will start blinking.

3.
The
Vacuum
switch. For the Insert to operate correctly the firebox needs to be
sealed. During the first 30 seconds after the unit has been turned on, the control
board will check to see if the switch senses negative pressure (Vacuum) in the
firebox of the Insert. If there is no negative pressure, the Insert will go into
“Safety shutdown” and the #2 LED will start blinking.

During “Normal Operation” a 60 second delay has been incorporated before the
unit shuts down when the board senses loss of vacuum. This is to accommodate
opening the doors during maintenance. Once the board senses loss of vacuum the
ON/OFF light will start blinking. While the light is blinking the control board will
not feed any fuel nor respond to any of the buttons. Once Vacuum has been
restored the unit will revert to normal operation.
“Internal Alarm” -
When the control board becomes unresponsive, the control board is
in Internal Alarm. The control board has sensed one of the Safety sensors. This may
cause the unit to go out and flash a Diagnostic Code. In some cases, after waiting
approximately 45 seconds the Insert will start responding to the control board again.
Many times, the cause of this is a change in the vacuum inside the firebox. This may be
