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. See Accessories.CAPACITY: 130 feet 3 /hour [4.2 meters 3 /hour]. 0000055306 00000 n If another gas leak is detected, tighten adapter screws, joints, and pipe connections. THIS SHORTS VALVE COIL AND MAY BURN OUT THE ANTICIPATOR IN THE THERMOSTAT.

Use only your hand to push down the reset button or turn the gas control knob. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. 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. 0000006449 00000 n This valve is only for vent free applications. Open the manual gas switch if the gas valve fails to operate and look to see if gas is flowing to the main burner or pilot. Do not exceed the input rating stamped on the appliance nameplate or manufacturer-recommended burner orifice pressure for the size orifice(s) used. The ON position allows pilot burner and main burner gas low under control of the thermostat and the two automatic valves. Outlet pressure to the main burner increases gradually from 0 in. I forgot to mention that I got the main burner to light on 2 occassions by tapping on either the gas pipe before the main shutoff valve, or on the honeywell gas millivolt valve itself. The pilot must be manually relit when normal burner operation is desired. Carefully check the main burner light off at the step pressure.

Vermont Castings, Majestic Products: DVR33, Window Frame Assembly Should be Removed Before Service Work, Troubleshooting Honeywell Millivolt Valve, Homeowner's Installation and Operating Manual. The power unit drops out, closing the safety valve and stopping all gas flow through the control.With the loss of outlet pressure, the second automatic valve closes and is held closed by spring pressure on the diaphragm. Safety shutoff or pilot gas proves complete shutdown since the safety shutoff valve permits main burner and pilot gas flow. 0000002758 00000 n This is an electrical connection and must be clean and dry. Turn off the main gas supply to the appliance. See Fig. 0000011066 00000 n It only takes a minute to sign up. Straight-through body pattern; right-angle adapters available for inlet and outlet. Locate gas control in a well-ventilated area. While holding tubing all the way in, slide compression fitting into place and engage threadsturn until finger tight. For the VR4200, when the gas control is installed external to the appliance, install the conduit cover on the conduit fitting. Do not secure conduit cover at this time. Millivolt systems have been the industry standard for decades, and are in some ways simpler to troubleshoot than electronic ignition systems. Why are physically impossible and logically impossible concepts considered separate in terms of probability? 0000042992 00000 n When the thermostat calls for heat, the automatic operator valve disc opens. Always install horizontal venting on a level plane.

If the pilot flame is engulfing the thermopile and you are not getting enough voltage to open the main gas valve then the thermopile may need to be replaced.Supervision is needed by a licensed HVAC Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.We've Partnered with TruTechTools.com! home heater furnace blower doesn't turn on [SOLVED], Goodman GM880804BNBA ignitor will not stay on. Thanks for that well-descriptive tips. Push in firmly to lock in place. 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. Adjust the thermostat several degrees higher than your current room temperature. Where the cost of an unexpected shutdown would be high, the system should be checked more ften. 14 when the: The power unit holds the safety shutoff valve disc off its seat, so gas can flow into the control. Otherwise, take the necessary steps to provide proper gas pressure to the gas control. Connect the pipe to gas control inlet and outlet. quick-connect terminals, must comply with applicable electrical codes and ordinances.Disconnect power supply before making wiring connections to prevent electrical shock or equipment damage. 10 0 obj <> endobj PRESSURE TAPPING: Inlet and outlet pressure taps accessible from the top of gas control. a. It may not display this or other websites correctly. This shuts off the pilot and main burner gas flow. Stand clear while lighting the main burner to prevent injury caused by hidden gas leaks, which could cause flashbacks in the appliance vestibule. 4. 0000126186 00000 n Resistance between the THTP & TH terminals must be 11.5 W0.2 W 2. They require the use of a 750 mv Powerpile generator (thermopile). The internal valve coil must then be connected to the topmost and bottommost of the four terminals. The best answers are voted up and rise to the top, Not the answer you're looking for? Check the regulator setting either with a manometer or by clocking the gas meter. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. TROUBLESHOOTING MILLIVOLT GAS VALVES PART # 023625 (NATURAL) & 023624 (LP) TroubleMillvoltGasV 04/16 . Wait five minutes to allow any gas in the combustion chamber to vent. Zero clearance sleeve is only required for combustible walls. See Fig. The Robertshaw - Uni-Line 700-500 and 710-500 Series millivolt gas valves are thermostatically actuated com- bination gas valves. Contact your Honeywell sales representative to request a gas valve with corrosion-resistant construction. 1. 0000098789 00000 n This product was the perfect replacement for the Honeywell thermopile in a circa 1975 gas fireplace unit. This is How to Wire the Thermopile to The 750mv Gas Valve for the Pilot and Main Gas Burners. Turn the gas control knob to the "On" position if the main burner does not turn on when the thermostat or controller is adjusted to start the appliance. Then the regulator valve is forced fully open by the timing diaphragm, which is operated by bleed gas. 0000049228 00000 n Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"?

Gas valves are not serviceable; the following are simple troubleshooting and description of how gas valves operate. 13. millivoltage automatic valve operator, and optional gas pressure regulator. 0000006141 00000 n See Fig. . Check the ratings given in the instructions and on the product to ensure the product is suitable for your application. The burner may relight at the full flow rate. 400 millivolts across the generator loadedcurrent flowing through the switches and valvesis about right. Turn off the gas supply valve to your appliance to test whether your valve is capable of shutting down properly. If it is re-energized within 60 seconds, it may bypass or shorten the length of the low-pressure step. 0000039877 00000 n 0000010874 00000 n 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 the voltage is dead or not as rated, replace the valve. I would recommend replacing all the wiring and controls and the pilot generator. 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. The low-pressureregulator maintains outlet pressure at the preset step rate for several seconds. Order number, SUPER TRADELINE or TRADELINE if desired.
