How do you ensure that a red herring doesn't violate Chekhov's gun? Assure the main gas supply valve is open and the pilot gas supply line is purged of air. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. Apply a moderate amount of good quality pipe compound to bushing, leaving two end threads bare. For push-in clip-type pilot burners: From beneath, insert the tip of the Q340 into the hole or barrel of the pilot burner. wc [0.9 kPa] outlet pressure). CHOOSE GAS CONTROL LOCATIONDo not locate the gas control where it may be affected by steam cleaning, high humidity, dripping water, corrosive chemicals, dust or grease accumulation, or excessive heat. The reduced pressure on the bottom of the automatic valve diaphragm repositions the diaphragm downward away from the valve seat, allowing main burner gas flow. They require the use of a 750 mv Powerpile generator (thermopile).

Refer to Fig. If resistance is outside of specifications listed, the gas valve must be replaced. This category contains Honeywell SmartValve, Gas Controls, Millivolts, Pressure Regulators, Gas Control Parts and Industrial Gas Valves. With the . Thanks. Attempt to light pilot burner flame following procedures in the Light the Pilot Burner Flame section. To adjust the pilot flame: LIGHT MAIN BURNERFollow the appliance manufacturer instructions or set the thermostat setting above room temperature to call for heat. I hope you enjoy and find them very beneficial! Failure to follow them could damage the product or cause a hazardous condition. Maintenance frequency must be determined individually for each application. Check the power supply rating on the valve and make sure it matches the available supply. Now I'm sure my problem's the thermopile. 7.). The PILOT position allows pilot burner gas flow only. All adjustments, wiring connections, and pilot outlets are accessible from the top of the gas control. Wait five minutes to allow any gas in the combustion chamber to vent.
