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.
