VACUUM SWITCH
Quadrafire 800 and 1100i A. The vacuum switch is located on the right side of the stove, just above the red call light and the reset button. This switch turns the feed system on when vacuum is present in the firebox. Check the rubber hose for leaks or cracks if the feed system fails to start. Also, be sure there is no restriction in the exhaust system and the exhaust blower is running. The vacuum switch is a safety device to shut off the feed motor under the conditions above.
B. If the exhaust or the heat exchanger system is dirty or plugged, the vacuum switch will keep the feed system from starting.
C. If the firebox door is open, the vacuum switch will keep the feed system from starting.
