Product Overview:

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.

Product Features:

  • Includes pilot flow adjustment screw
  • Easy to install, adjust and service; all adjustments and connections are accessible from top of control
  • Add separate energy cutoff (ECO) where codes call for dual safety shutoff
  • Complete safety shutoff on pilot flame failure
  • LITE-RITE (OFF-PILOT-ON) lighting sequence
  • ECO connector for V800 models, Part No. 392451-1
