This is a Normally Closed switch located near the left-hand-side of the stove and mounted
directly on the sheet metal Air Jacket. Under normal operating conditions the Air jacket
temperature registers below 250°F and the High-Limit 250°F Disc will read Normally Closed;
this condition supplies power to the Anger Motor. During extreme operating conditions where
temperatures within the sheet metal Air Jacket exceed 250°F the power to the Auger Motor will
become interrupted and immediately shutdown the fuel feed system. The auger will not operate
until the switch has been manually reset.
The Room Air Fan, the Combustion Fan and the Versa Grate Motor continue to run until the
Proof of Fire Switch measures temperatures below 90 degrees in the exhaust system and the
P.O.F. switch drops out. At this time the #3 Diagnostic LED light will start blinking with a First
Generation Digital Control Board and the #2 and #3 LED light flashes with a second Generation
Control Board. (First Generation Control Boards do not have the Thermostat Slide Switch on the
front of the board .All other generations have the slide switch.)
Remember: If the switch trips due to excessive temperatures, it must be reset to
allow the auger to run.
Proof of Fire Switch
Proof of Fire Switch - 110°F Disc, Normally Open - To troubleshoot the High
Limit switch refer to the section covering the diagnostic features of the Control Board
covering the #3 LED diagnostic light or check the Troubleshooting Flow Charts.
The Proof of Fire switch will sense if the exhaust temperatures rise above 110° F. This
indicates a successful lighting of the stove. Once the Proof of Fire switch closes, the
Convection Fan turns on and blows warm air into the room and the control board
switches from the” Start-up” program to the “Normal Operation” Program.
The #3 LED light will start blinking only if the temperature drops in the Exhaust system
and the Proof of Fire switch opens without the stove first being shut off.
Hopper Lid Switch
Hopper lid switch – This switch is wired to the Normally Open connectors of the
switch. Closing the hopper lid will close the circuit to the auger motor and feed pellets to
the Burn Pot.
Mechanical Components in the Stove
Door Assembly
Location: The door assembly is in the front center of the stove. The assembly
consists of the cast iron door on the Prescott EXL & EXP models, or a
metal frame door on the Hastings models or a Bay metal frame door, the
window, the door latch and gasket.
Purpose: The door provides access to the firebox and holds the window glass. The
gaskets provide airtight seals into the firebox. The latch secures the door.
It must remain closed during operation of the stove. The gaskets must
make an airtight seal to create Negative Pressure for the stove to operate
properly.
