The second automatic valve diaphragm, controlled by the servo pressure regulator, opens and adjusts gas flow as long as the system is powered and the pilot is burning. Do I need a thermal expansion tank if I already have a pressure tank? This increases gas pressure under the automatic valve and repositions the valve disc closer to the seat. Pilot gas flows through a port in the ushing around the reset button shaft to the pilot burner. There must be two terminals in this connector block that powers the gas valve coil. Follow these warnings exactly: CAUTIONNever apply a jumper across or short the valve coil terminals. 0000003926 00000 n If tubing is used, ensure the ends are square, deburred and clean. In replacement applications, locate the gas control in the same location as the old gas control. Apply a moderate amount of good quality pipe compound to bushing, leaving two end threads bare. 0000062529 00000 n 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. It has been obsolete for over 30 yrs now. See Fig. Fig. All adjustments, wiring connections, and pilot outlets are accessible from the top of the gas control. 2 or 3) clockwise. If resistance is outside of specifications listed, the gas valve must be replaced. Hold each tester wand on the multimeter to one of the terminals on the gas valve. Resistance between THTP & TP must be 10.0 W 0.2 W Set your thermostat to under the room's current temperature and let at least one minute pass to allow the appliance to attempt to get fuel. Your problem seems to involve large -- really large -- "industrial size" issues. Gas valve troubleshooting looks for a problem. LP to natural gas conversion kit available for standard and slow-opening models. Release button; the pilot should remain lit. Do not force the gas control knob. .

Install the Q340A asfollows: Connect ThermocoupleConnect thermocouple lead as shown in Fig. Connect the other end of the tubing to the pilot burner according to pilot burner manufacturer instructions. TABLE 6MAXIMUM LENGTH OF SUPPLEMENTARY LIMIT LEADWIRES WHEN USING Q309A THERMOCOUPLE. There should not be a flame-up there if the valve is working correctly. Use an ac voltmeter to measure the voltage across terminals TH and TR. The low-pressureregulator maintains outlet pressure at the preset step rate for several seconds. 0000018745 00000 n If above 11 ohms, replace the gas control. This decreases gas pressure under the second automatic valve diaphragm and repositions the valve disc further from the seat. Did this satellite streak past the Hubble Space Telescope so close that it was out of focus? Insert bushing in gas control and thread pipe carefully into bushing until tight. I would not work on it, without completely replaceing the gas control system, and the furnace may not be worth that expense. Most common. Adjustable servo regulator effectively maintains almost constant gas output pressure under wide fluctuation in gas supply pressure. I would recommend replacing all the wiring and controls and the pilot generator. These controls combine a manual gas cock, automatic pilot safety valve and a millivolt operator.
