Outlet pressure to the main burner increases gradually from 0 in. Check the wiring between the thermocouple and the gas control valve operator. The generator, heated by the pilot burner flame, pro- . ny outlet pressure change is immediately reflected back to the pressure regulator diaphragm, which repositions to change the flow rate through the regulator valve and, thus, through the diaphragm-operated automatic valve. Square off and remove burrs from the end of the tubing. 0000011045 00000 n Hold down the gas control knob about one minute, then release. If the appliance uses LP (bottled) gas, be sure to smell next to the floor because LP gas is heavier than air. As the pressure inside the gas control and underneath the automatic valve diaphragm equalizes, spring pressure closes the second automatic valve to provide a second barrier to gas flow. 0000007879 00000 n This type of gas valve used a single thermocouple. Helping You to Do It Yourself!

Bubbles indicate a gas leak. This material is proprietary to Honeywell Limited and shall not be reproduced, copied or used in any manner without prior written consent of . I searched for that gas valve, and found this one as the replacement: I would seriously consider what Jimbo said, but, yes, if you bypass the t'stat and the limit switch with jumper wires and the pilot is on, the valve should open if the schematic is what I think it is. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. 0000006973 00000 n This makes it ideal for fireplace and space heating uses that are vent free. 00. With the main burner operating, check the gas control flow rate using the meter clocking method or check the gas pressure using a manometer connected to the gas control outlet pressure tap. Hold each tester wand on the multimeter to one of the terminals on the gas valve. The pilot light is auto so when the thermostat calls for heat, a spark is sent to the ignition lighting up the pilot. To avoid the dangerous accumulation of fuel gas, turn off the gas supply at the appliance service valve before starting the installation, and perform Gas Leak Test after completion of installation. It only takes a minute to sign up. The electrical/scientific basis for millivolt systems is the Seebeck Is there a solution to add special characters from software and how to do it.
