Readjust the full rate outlet pressure if necessary to improve light off characteristics. Follow these warnings exactly: CAUTIONNever apply a jumper across or short the valve coil terminals. Replace the part if the gas leak cannot be stopped. If pilot burner flame still goes out, measure the open and closed thermocouple output voltage. When the pilot goes out or becomes too small to sustain normal ignition. SPECIFICATIONS Main Gas Connection: Valve: 3/8 in. Dusty, wet, or corrosive environment.

If so, then the thermocouple or thermopile is generating enough voltage to keep the safety valve open. Because gas is involved, problems with gas valves are a major safety concern. The diaphragm-operated second automatic valve opens under the control of the regulator and closes if gas or power supply is interrupted. This increases gas pressure under the automatic valve and repositions the valve disc closer to the seat. I show you how to Light the Pilot and Power the Main Burner! These controls combine a manual gas cock, automatic pilot safety valve and a millivolt operator. The low-pressureregulator maintains outlet pressure at the preset step rate for several seconds. 0000012011 00000 n
Turn the gas control knob to the "On" position if the main burner does not turn on when the thermostat or controller is adjusted to start the appliance. This may burn out the heat anticipator in the thermostat. One more troubleshooting tip, on a residential gas furnace if a gas valve is not "clicking" meaning it's apparently not receiving 24 volts you can jump directly off of the control board using the R and the C terminals, R to one terminal on gas valve and C to the other terminal on gas valve (or wherever else you can retain 24 volts from) to the gas valve.
