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 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, cuttin power to the feeder mo-
tor 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 operating.
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.
