Field Controls 80+ Gas Draft Induced Furnace Vent Kit

Designed for operation with natural gas and LP gas. The thermostat calls for heat and energizes a relay which activates the power venter. After the venter motor has come up to speed, the pressure switch closes. This closes the circuit to the burner and allows the burner to fire. After the heating requirement has been satisfied, the thermostat circuit will open and deactivate the burner. The power venter operates for a period of time after the burner has shut off to purge remaining flue gases.
