VS820 Millivoltage Combination Gas Controls
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.
• 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 V800 models, Part No. 392451-1.
Application: Self-powered automatic control. Use with 750 mV pilot
generator.
