Residential Comfort/Combustion : Combustion Controls : Gas Valves, Residential : Millivolt Gas Valves : VS820 : VS820A1088/U
750mV Standard Opening Gas Valve. 3/4 x 3/4" with 1/2" side outlets. Set 3.5" WC.
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.
Features
- Include 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 VS820 models, Part No. 392451-1.
