Type 36C12 combines step-opening main operator in the same package with main regulator, 3-position Gas Cock, 100% Shut-off Pilot and Natural-LP Gas Selector. This control provides a definite step on both Natural and LP gases by opening initially to about 1⁄2 input for approximately 2 seconds. Then it fully opens. After thermostat is satisfied, about 30 seconds is required for valve to recycle before it will provide a complete step on the next thermostat cycle. This control is also equipped with a Natural-LP Gas Selector that provides a simple method of changing the regulator setting back and forth between Natural and LP gases. These controls are thermocouple-operated and may be mounted in any position except upside down. Pressure Regulator Setting: UP Position - Natural Gas, 3 1⁄2" W.C. DOWN Position - LP Gas, 11.0" W.C. Pressure Rating: 1⁄2 PSI Ambient Temperature: -40° to 175°F |
