Honeywell VR8345 Direct Intermittent Pilot 1-Stage Compact Natural/LP Combination Gas Control Valve, 3/4"

honeywell g674-103

These gas controls combine a Lite-Rite manual gas cock, safety shutoff pilotstat assembly, millivoltage automatic valve operator, and optional gas pressure regulator. They require the use of a 750 mV powerpile generator (thermopile). The generator, heated by the pilot burner flame, provides the electrical energy to operate the combination gas control. A millivoltage thermostat with suitable accessory controls completes the automatic control system for the heating appliance.
