To Check The Vent Pressure Switch: This furnace utilizes a vent pressure switch which prevents the furnace from operating should any portion of the vent system become restricted or a venter failure occur. To check this switch, place the furnace in operation and remove the hose from the switch. The gas burners will extinguish. Replacing the hose will allow the furnace to operate normally.
