Safety Features

The low draft sensor which is a vacuum differential switch, monitors the negative pressure (draft) in the firebox through a port on the rear of the feeder. Poor draft will result in an interruption of power to the feeder and the igniter. Poor draft can be caused by blockage in the exhaust, excessive build-up on the combustion blower fan blades, a failed combustion blower, or a door or other opening to the firebox not sealed properly. The hopper lid position switch, located in the right rear corner of the hopper opening, will also interrupt power to the feeder and igniter if the hopper lid is not closed properly. The circuit board is monitoring the position of these switches. During a feed cycle, if either of these switches were to open, the feed motor light on the control will stay illuminated with the power being interrupted by the switch. If the switch opens when the cycle is at rest, the power lights for the feed motor or igniter will not illuminate. Be sure all doors, including the hopper lid, are securely closed when operating the appliance.
