caused by excessive wind or by opening the Firebox door. The control board will monitor
the vacuum switch and resume normal operation if the vacuum returns to normal.

Safety Features
1.
”High Limit” switch”,
an overheat safety switch will shut off the fuel feed if the
Insert reaches temperatures above normal operating temperature. This is a
“Normally Closed” switch. If the High limit switch trips several times, the
problem in the Insert
must
be diagnosed before the unit is put back into service,
(Defective Room Fan, dirty Room Fan, defective High Limit switch or possibly a
bad Control Board)
2.
Vacuum switch
also called the
Negative pressure switch
. When the Insert is
turned on the Exhaust fan will create a negative pressure in the firebox. The
control board continually checks to see if Negative Pressure (vacuum) is present
during operation of the Insert. If the exhaust venting system becomes clogged or
obstructed, the firebox door is left open or the exhaust fan quits working the
control board will go into “Safety shutdown”. There is a 60 second window to
allow for cleaning the glass before then unit shuts down. This is sufficient for the
Daily Maintenance
3.
Proof of Fire switch
also called the
P.O.F.
This senses the temperature rise in the
exhaust system. The switch is “Normally Open” and closes the circuit at 110
degrees. The Insert will shut down if temperatures above 110 degrees F are not
sensed during start up or if the temperature drops below 110 degrees during
normal operation.
4.
Hopper Lid Switch.
The hopper lid switch will shut off the auger motor when
the hopper lid is open. Be sure the lid closes completely when refilling the hopper
or the unit will shut down
