Do I need a thermal expansion tank if I already have a pressure tank? to protect them and prevent gas from leaking, and discourage tampering by untrained people. Regular preventive maintenance is important in applications that place a heavy load on system control such as in the commercial looking and agricultural and industrial industries because: The VR8200, VR4200 gas controls provide 3-position (OFF-PILOT-ON) manual control of gas flow. 0000068110 00000 n Attempted disassembly or repair may damage the gas control. Water heater won't light? Thermopile readings: With all wires connected, with the pilot on and burners off, the thermopile reading at the TP & THTP terminals should be ~325mV. Light the main burner. Gas valves exposed to high ammonia conditions, i.e., those used in greenhouses or animal barns may fail in one or two years. The automatic pilot safety is separate from the gas cock and provides gas shut Off in case of pilot Outage. Run pipe or tubing to the gas control. THIS SHORTS VALVE COIL AND MAY BURN OUT THE ANTICIPATOR IN THE THERMOSTAT. Wait five minutes to allow any gas in the combustion chamber to vent. SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION. I go over how it is Wired, what Voltages you should be reading while the flame is present and the voltages needed for the pilot valve and main gas valve to work correctly. Remove the thermopile wiring connector from the gas control. 400 millivolts across the generator loadedcurrent flowing through the switches and valvesis about right. .

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. Zero clearance sleeve is only required for combustible walls. 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. When the pilot goes out or becomes too small to sustain normal ignition. Turn the pressure regulator adjustment screw clockwise. THEY ARE NOT INTERNALLY WIRED TO THE CONTROL CIRCUIT OR TO THE GROUND.

If the regulator cannot be adjusted and supply pressure is in the normal range, replace the gas control. If tubing is used, ensure the ends are square, deburred and clean. And after two or so minutes, the gas chambers will be lit. If: Measure the open and closed thermocouple output voltages and compare to the acceptable range charts in the thermocouple specifications or in the Gas Controls Handbook. 0000006677 00000 n 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. How do I test Millivolt valve system when Pilot is on I hope you enjoy and find them very beneficial! Outstanding!

Several troubleshooting methods applied to and including bypassing the thermostat but failed to yield any results. Please comment and ask for videos that you would like to see in the future! The Robertshaw - Uni-Line 700-500 and 710-500 Series millivolt gas valves are thermostatically actuated com- bination gas valves. Some tips regarding the Honeywell Millivolt valve: Always ensure the switch is in the off position when lighting the pilot. We might be able to do something about it. Connect control circuit to gas control terminals. Such heavy cycling wears out the gas control in one to two years. Do not exceed the input rating stamped on the appliance nameplate or manufacturer-recommended burner orifice pressure for the size orifice(s) used. The minimum regulated capacity is 20 feet 3 /hour [0.6 meters 3 /hour]. Then the regulator valve is forced fully open by the timing diaphragm, which is operated by bleed gas. 0000028651 00000 n The VR8200 Continuous Pilot Dual Automatic Valve Combination Gas Controls are used in gas-fired, standing pilot appliances.
