Intermittent Pilot
Most usually found on some induced draft furnaces, this pilot ignites with a high voltage spark only when the thermostat calls for heat. Once the intermittent pilot (IP) is lit and the main burner senses the pilot flame (flame sensing rod), the main burner will ignite.

The furnace gas valve for this type of furnace is identifiable with its solenoid designations PV PV/MV MV (MV (main valve) PV (pilot valve) and PV/MV common).
