The Low Draft Pressure Switch is a differential pressure switch
that monitors the negative pressure (Draft) in the rebox. If the
draft becomes too low for proper combustion, the switch opens,
cutting power to the feed motor and the igniter circuits. This switch
is connected into the AC (high voltage) wiring.
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.
Backdraft Damper Assembly
Always check to see if the damper
plate swings freely inward and that
the seating edges are not covered
