The Combustion Motor Fuse is a thermal overload one-time fuse link within the motor windings. Should the distri- bution motor fail with the unit operating over 80%, this fuse will protect the other components by melting off at a set tempera- ture. With the fuse blown, the combustion motor will stop.In turn, the feeder motor will not operate and the stove will go out. This may only happen when the unit is on Maximum (#7 on the Temperature Dial, #6 on the Feed Adjuster and Distribution blower not operating). If this fuse does blow, the unit will need service.

The Control Board/ESP combination is responsible for all high limit safety control. There are 2 high limits, one normal operation high limit and one backup high limit. The control has an automatic diagnostic circuit that continuously monitors the ESP and Room Sensor for faults. If a fault should occur, the control sends a status alert and at the same time the unit goes down to minimum feed/minimum burn as a safety condition.

The Low Draft Pressure Switch is a differential pres- sure switch that senses the pressure between the firebox and the room. If the pressure becomes too low for proper combustion, the switch opens, turning off the feeder motor and the igniter element. This switch is connected into the AC (high voltage) wires; therefore, the control may show the feeder motor and igniter lights "on" but they are not.
