If it is flowing, measure the voltage between the 24V Hot and 24V Common leads to the SmartValve. And, it was very cost competitive to other non-Honeywell thermopiles. Set thermostat to the desired temperature. You should NOT short out the t'stat terminals to check it. Gas control is a safety device. 250 items. But it has been reliable for a long time. (supposedly so they could fix them :yes: ), Cool. In this HVAC Furnace Video, I go over the Operation and Troubleshooting of a 750 Millivolt Gas Valve and Thermopile/PowerPile. When Pilot Flame Goes OutWhen the pilot flame goes out or is too small to reliably light the main burner, thermocouple output drops below the power unit hold-in valve. 0000027628 00000 n
Thermopile readings: With all wires connected, with the pilot on and burners off, the thermopile reading at the TP & THTP terminals should be ~325mV. Tubing installation must comply with approved standards and practices. Outstanding! 0000041802 00000 n

Check the power supply rating on the valve and make sure it matches the available supply. 5. If tubing is used, obtain a tube-to-pipe coupling to connect the tubing to the gas control. Styling contours by colour and by line thickness in QGIS. 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. Combination 1/4 inch quick-connect and screw terminals (includes convenience terminals). These Videos are all part of our Training Series on HVACR Service, Installation, Preventative Maintenance, General Knowledge, and Tips. If you then smell gas in the appliance area or near the floor in an LP installation, immediately shut off the manual valve in the gas piping to the appliance or, with LP, shut off at the tank. 2 and 3. Gas control operation is described in more detail below.VALVE POSITION DURING THERMOSTAT OFFCYCLEThe valve is positioned as shown in Fig. If the inlet pressure is in the normal range (refer to Table 7 or 8), replace the existing gas control. Refer to Table 7 or 8 for factory-set nominaloutlet pressures and adjustment ranges. Slip the compression fitting over the tubing and slide out of the way. The pilot must be manually relit when normal burner operation is desired. 0000001836 00000 n - Reg. When the thermostat calls for heat, the first automatic valve and the second automatic valve operator open. Do not touch any electrical switch or use the phone. The Fora platform includes forum software by XenForo. '', New members: Adding your location to your profile helps in many ways.--M--, valves" thread in the HVAC forum, someone wanted to know how a gas valve worked. Hold each tester wand on the multimeter to one of the terminals on the gas valve. 0000002167 00000 n
If outlet pressure begins to fall, the pressure regulator diaphragm moves slightly lower allowing ore to flow to the gas control outlet. Set your voltmeter for the proper voltage that is, above 24 volts. Replace the thermocouple if voltages are outside the acceptable range. the manual gas control knob is in the ON position. 00. Zero clearance sleeve is only required for combustible walls. Fig. 10 Easy Things to Check When Troubleshooting a Furnace Gas Valve. Do not bend tubing at gas control or pilot burner after compression fitting has been tightened, as this may result in a gas leakage at the connection. If you have not I will give some ideas. See Table 3. an Elbow (angle) flange cannot provide a right-hand inlet when the ECO connector is used.NOTE: Flange Kits include one flange with attached O-ring and four mounting screws. If pilot burner flame still goes out, measure the open and closed thermocouple output voltage. 0000006141 00000 n

If you'd like to support the site, please allow ads. If you don't test, it's just a. See Fig. Install thermostat, and other controls as required. In replacement applications, locate the gas control in the same location as the old gas control. This diverts gas flow from the automatic valve diaphragm and causes a reduction of pressure on the underside of this diaphragm. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? For your safety, read the following warnings before lighting the appliance: WARNING: BEFORE DOING ANY GAS CONTROL SERVICE WORK, REMOVE GLASS FRONT. I was just wondering about this the other day. If pilot burner flame still will not light: Assure the gas control knob is held in at least one minute to allow the thermocouple time to heat. There should not be a flame-up there if the valve is working correctly.

PERFORM GAS LEAK TEST WARNING!FIRE OR EXPLOSION HAZARDS CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.Check for gas leaks with rich soap and water solution any time work is done on a gas control. Did this satellite streak past the Hubble Space Telescope so close that it was out of focus? This includes a WIRING DIAGRAM. There is a heat anticipator coil in there which limits current to the valve, and shorting that out can damage the valve. Refer to Fig. Yes, this shows the pilot gen. in series with the limit switch in series with the t'stat. 0000052168 00000 n
As for the gas valve it is probably a "general controls" valve but any 800 millivolt gas valve can be used as a replacement.
