One more troubleshooting tip, on a residential gas furnace if a gas valve is not "clicking" meaning it's apparently not receiving 24 volts you can jump directly off of the control board using the R and the C terminals, R to one terminal on gas valve and C to the other terminal on gas valve (or wherever else you can retain 24 volts from) to the gas valve. Only the gas valve manufacturer or someone certified by the manufacturer of the gas valve can make repairs. Use only glass approved by Vermont Castings, Majestic Products on this fireplace. There should not be a flame-up there if the valve is working correctly. If the appliance is a hot water heater but it's not firing up, the thermopile might be weak.

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. WARNING!FIRE OR EXPLOSION HAZARDS CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY OR DEATH.Do not disassemble the gas control; it contains no replaceable components. Use a wrench on the square ends of the gas control. Step-Opening Pressure Regulation (VR8200C,P andVR4200P)Step-opening gas controls actually combine two pressure regulators, one for the low pressure and one for the full-rate pressure. Test the voltage using an AC voltmeter. This decreases gas pressure under the second automatic valve diaphragm and repositions the valve disc further from the seat. SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION. In this HVAC Furnace Video, I go over the Operation and Troubleshooting of a 750 Millivolt Gas Valve and Thermopile/PowerPile. Resistance between the THTP & TH terminals must be 11.5 W0.2 W 2. Tubing installation must comply with approved standards and practices. Any help and/or comment would be greatly appreciated.

CONVENIENCE TERMINALS SERVE AS A TIE POINT ONLY. Yes, this shows the pilot gen. in series with the limit switch in series with the t'stat. The pilot works fine but the main burner does not come on by the wall mounted thermostat or the manual on/off switch. Loss of power closes the automatic valves, but leaves the pilot lit, ready to return to normal service when power is restored. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. 0000041802 00000 n Intermittent use.

Thus, the flow of gas through the second automatic valve is increased, and outlet pressure rises to the desired level.Slow-Opening Pressure Regulation (VR8200H and VR4200H); Delayed and Slow-opening Regulation (VR8200J)Slow-opening gas controls function the same as standard models except that when the thermostat calls for heat, the second automatic alve pens gradually. Usually this problem can be resolved by using an adapter. CAUTION!Do not apply a jumper across or short the valve coil terminals. Do I need a thermal expansion tank if I already have a pressure tank? 0000006141 00000 n Is there a solution to add special characters from software and how to do it. Furnace gas valves cannot be repaired. 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. cut tubing to the desired length and bend as necessary for routing to pilot burner.

Always install sediment trap in gas supply line to prevent contamination of gas control. This may burn out the heat anticipator in the thermostat or damage the DI module.IMPORTANT: Allow 60 seconds after shutdown before reenergizing the step-opening model to assure light off at step pressure. Do not make sharp bends or deform the tubing. Lv 4. 2 or 3. If the regulator cannot be adjusted and supply pressure is in the normal range, replace the gas control. The combination of spring pressure under the second automatic valve diaphragm and the lack of outlet pressure holds the diaphragm firmly closed. CHECK AND ADJUST GAS INPUT TO THE MAIN BURNER, Standard-Opening and Slow-Opening Pressure Regulator, Step-Opening Pressure Regulator and Delayed and Step-Opening Pressure Regulator. Insert and tighten the screws provided with the flange. Advertisement Tighten the screws to 25 inch-pounds of torque to provide a gas-tight seal. 0000001836 00000 n Slip the compression fitting over the tubing and slide out of the way.
