3/4 in. NPT x 3/4 in. NPT PowerPile Millivolt Combination Gas Valve with Step: 0.9 in. wc non-adjust
Quantity in Basket: None
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, pro- vides the electrical energy to operate the combina- tion gas control. A millivoltage thermostat with suitable accessory controls completes the automatic control system for the heating appliance. Models equipped with the standard pressure regulator are identified by the suffix letter “A“ WS820A.j Models without pressure regulator carry the suffix letter “6” (VS820B). Suffix letter “C” (VS82OC) identifies models having step opening type regulators. Pressure regulators and operator are standardized and interchangeable on all models in the two capacity ranges - 225 and 335 cubic feet per hour.
• 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.
