The power unit drops out, closing the safety valve and stopping all gas flow through the control.With the loss of outlet pressure, the second automatic valve closes and is held closed by spring pressure on the diaphragm. Seems my new millvolt gas valve turns off PILOT and MAIN BURNERS. The small valve seat attached to the reset button closes and shuts off the pilot gas flow. 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. While holding tubing all the way in, slide compression fitting into place and engage threadsturn until finger tight. Install ThermocoupleThe Q340A Thermocouple (with adapters) is provided with SUPER TRADELINE models of the VR8200A. I forgot to mention that I got the main burner to light on 2 occassions by tapping on either the gas pipe before the main shutoff valve, or on the honeywell gas millivolt valve itself.

Do not thread pipe too far. Thanks. Always install sediment trap in gas supply line to prevent contamination of gas control. If the appliance uses LP (bottled) gas, be sure to smell next to the floor because LP gas is heavier than air. Disconnect power supply before wiring to prevent electrical shock or equipment damage. Connect the other end of the tubing to the pilot burner according to pilot burner manufacturer instructions. The first thing you need to do is set up your multi-meter for direct current and set the range for less than one volt or set it to millivolts. It may not display this or other websites correctly. This increases gas pressure under the automatic valve and repositions the valve disc closer to the seat. Compare it to the acceptable range charts in the thermocouple specifications or in the Gas Controls Handbook. Gas valves nowadays are one piece with 100% shutoff for the pilot flame gas and shutoff valve etc all in one valve. One Q340A 36-inch thermocouple with adapters and clip. Install the new plastic pressure regulator adjustment screw so that the top of the screw is flush (level) with the top of the regulator. Troubleshooting the valve and looking for known common issues will give you peace of mind by ensuring the safe operation of your Honeywell appliance. IF CHECKING GAS INPUT BY CLOCKING THE GAS METER: IF CHECKING GAS INPUT WITH A MANOMETER (PRESSURE GAUGE): The gas control outlet pressure should match the manifold pressure listed on the appliance nameplate.
