13. Vacuum Switch
The vacuum switch is located on the right side of the appliance under the feed motor, behind right side panel. Its
vacuum hose connects to the drop tube. This switch turns the feed system on when vacuum is present in the firebox.
The vacuum switch is a safety device to shut off the feed motor if the exhaust or the heat exchanger system is dirty,
plugged, or if the firebox door is open.
