A bad gas valve in a Honeywell appliance such as a water heater or furnace that is powered by natural gas can go bad and affect the performance of the unit. 0000007638 00000 n This is a very useful thread and am learning a lot from it partly because of my situation with my current Weil McClain boiler. The small valve seat attached to the reset button closes and shuts off the pilot gas flow. Please comment and ask for videos that you would like to see in the future! 0000002201 00000 n Do I need a thermal expansion tank if I already have a pressure tank? 0000003485 00000 n 0000041802 00000 n 0000049205 00000 n %PDF-1.3 % 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. Assure the main gas supply valve is open and the pilot gas supply line is purged of air. To convert control from one gas to another: INSTALL ADAPTERS TO GAS CONTROLIf adapters are to be installed on the gas control, mount them as follows: USING ADAPTERS TO SOLVE SWING RADIUS PROBLEMSIn some field service applications, it is difficult or impossible to thread the gas control onto the gas supply pipe because of space limitations. 0000031335 00000 n inlet and 1/2 inch outlet; adapters available for 3/8 or 3/4 inch. Tubing installation must comply with approved standards and practices. Works with the majority of millivolt gas valves; Push-in clip for easy installation included; . A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. Ensure the ambient temperature does not exceed the ambient temperature ratings for each component. Appliances that may cycle 120,000 times annually should be checked monthly. startxref 0000008826 00000 n 0000013040 00000 n JavaScript is disabled. Furnace gas valves cannot be repaired. The main burner should go off and the pilot should remain lit. cut tubing to the desired length and bend as necessary for routing to pilot burner. Dont touch any electrical switch or use the phone. Set your voltmeter for the proper voltage that is, above 24 volts. It must be replaced in case of any physical damage such as bent terminals, missing or broken parts, stripped threads, or evidence of exposure to heat. 0000055329 00000 n 0000049228 00000 n Mount the gas control 0-90 degrees, in any direction, from the upright position of the gas control knob, including vertically. Troubleshooting the valve and looking for known common issues will give you peace of mind by ensuring the safe operation of your Honeywell appliance. Since these environments can cause the gas control to deteriorate more rapidly, the system should e checked more often. If the desired outlet gas pressure or gas flow rate cannot be achieved by adjusting the gas control, check the gas control inlet pressure using a manometer at the inlet pressure tap. Adjustable servo regulator effectively maintains almost constant gas output pressure under wide fluctuation in gas supply pressure. 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. . Note that using an adapter increases the overall length of the gas control. Thanks. Straight-through body pattern; right-angle adapters available for inlet and outlet. . WARNING!FIRE OR EXPLOSION HAZARDS CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH. Connect the pipe to gas control inlet and outlet. Prices are the same as normal- https://www.amazon.com/shop/acservicetech The opening is slowed because a gas flow restrictor in the passage from the second automatic operator slows the rate at hich gas pressure is reduced under the second automatic valve diaphragm after the automatic operator opens. The gas control should e replaced if: It does not perform properly on checkout or troubleshooting. Check fireplace to make sure it is levelled and properly positioned. 0000000016 00000 n The gas control knob is hard to turn or push down, or it fails to pop back up when released.

I'll show you how to troubleshoot and diagnose the problem with your water heater and Honeywell gas val. And we already know that the t'stat + terminal is jumpered to the t'couple + terminal, and that the t'stat - terminal is jumpered to the limit switch + terminal. As with the millivolt system, you'll be testing a series of components to locate the faulty part.

If the red reset button stays depressed after it is released, replace the gas control. This may burn out the heat anticipator in the thermostat. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. Usually this problem can be resolved by using an adapter. Paint all pipe connections upstream of the gas control with a rich soap and water solution. Mount the gas control so gas flow is in the direction of the arrow on the bottom of the gas control. Compare it to the acceptable range charts in the thermocouple specifications or in the Gas Controls Handbook. It looks like this: the thermopile is a generatorputs out up to 400 MV. 0000003838 00000 n TABLE 8PRESSURE REGULATOR SPECIFICATION PRESSURES IN kPa. 0000062529 00000 n In this HVAC Furnace Video, I go over the Operation and Troubleshooting of a 750 Millivolt Gas Valve and Thermopile/PowerPile. You should NOT short out the t'stat terminals to check it. The adapter is installed on the end of the supply pipe in place of the gas control, following the same precautions and instructions that are used for installing the gas control. Ensure the installer is a trained, experienced service technician. Therefore, this unit may not exactly match the listed specifications. WHEN THE THERMOSTAT CALLS FOR HEATThe gas control allows pilot and main burner gas flow during the thermostat ON cycle, as shown in Fig. 0 Check your instruction manual to determine the voltage that should be running at your control valve circuit. This includes a WIRING DIAGRAM. Fig. the robertshaw link gives max lengths vs. gauge. The problem I'm having is very simple. 0000010874 00000 n The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. For the VR4200, when the gas control is installed external to the appliance, install the conduit cover on the conduit fitting.

If it then "clicks" meaning it is opening with voltage supplied to it than most likely it's not the gas valve which is bad. Remove the thermopile wiring connector from the gas control. Making statements based on opinion; back them up with references or personal experience. Check the power unit resistance. 0000139236 00000 n 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. Tech Guru. to protect them and prevent gas from leaking, and discourage tampering by untrained people. Styling contours by colour and by line thickness in QGIS. Such heavy cycling wears out the gas control in one to two years. Seems my new millvolt gas valve turns off PILOT and MAIN BURNERS. After the adapter is installed, the gas control is attached to the adapter as outlined above. (supposedly so they could fix them :yes: ), Cool. I'm looking for help identifying what model it actually is (so I can search for information specific to it) or ideas on what might be wrong. Loss of pilot flame or flame too small to reliably light the main burner closes the safety shutoff valve and the second automatic valve. (supposedly so they could fix them :yes: ). If the regulator cannot be adjusted and supply pressure is in the normal range, replace the gas control. 0000018497 00000 n Only the gas valve manufacturer or someone certified by the manufacturer of the gas valve can make repairs. 00. I would recommend replacing all the wiring and controls and the pilot generator. Follow these warnings exactly: CAUTIONNever apply a jumper across or short the valve coil terminals. . There must be two terminals in this connector block that powers the gas valve coil. Then the regulator valve is forced fully open by the timing diaphragm, which is operated by bleed gas. Thus the flow of gas through the second automatic valve is reduced, and outlet pressure falls to the desired level. Remove seal over gas control inlet or outlet.
