The automatic pilot safety is separate from the gas cock and provides gas shut Off in case of pilot Outage. If desired outlet pressure or flow rate cannot be achieved by adjusting the gas control, check the inlet pressure using a manometer at the inlet pressure tap or upstream of the gas control. Check the wiring between the thermocouple and the gas control valve operator. I go over how it is Wired, wha. Home Improvement Stack Exchange is a question and answer site for contractors and serious DIYers. 0 With the main burner in operation, paint all pipe joints (including adapters) and gas control inlet and outlet with rich soap and water solution. CAUTION!Do not apply a jumper across or short the valve coil terminals. This behaviour is consistent with what I have seen/heard when the Honeywell valves begin to fail. 0000001377 00000 n 0000062506 00000 n Filter.

At least having yours done professionally would appear to put you in a position of a tax deduction for repairing it. 7.). LP to natural gas conversion kit available for standard and slow-opening models. Read these instructions carefully. For use in standing pilot appliances. The gas control knob must be held depressed or the thermocouple must be heated sufficiently to hold the safety control valve open.ON: Permits main burner and pilot gas flow. Compare it to the acceptable range charts in the thermocouple specifications or in the Gas Controls Handbook. 0000036872 00000 n Always install sediment trap in gas supply line to prevent contamination of gas control. Square off and remove burrs from the end of the tubing. Fig. Unscrew compression fitting from the pilot outlet (Fig. This shuts off the pilot and main burner gas flow. It may not display this or other websites correctly. Prices are the same as normal- https://www.amazon.com/shop/acservicetech Do not secure conduit cover at this time. If the gas control knob or reset button will not operate by hand, or if the reset button stays depressed after it is released, the gas control should be replaced by a qualified service technician. Because gas is involved, problems with gas valves are a major safety concern. 0000016105 00000 n Ensure the ambient temperature does not exceed the ambient temperature ratings for each component. We might be able to do something about it. Do not use a gas control set for natural gas on an LP gas system or a gas control set for LP gas on a natural gas system.

If the regulator cannot be adjusted and supply pressure is in the normal range, replace the gas control. 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. Tighten the screws to 25 inch-pounds of torque to provide a gas-tight seal. When the thermostat calls for eat, the first automatic valve and the second automatic valve operator are energized. 0000028639 00000 n To check for gas pipe leaks, put soap on the pipe connecting to the valve, if it bubbles, it means there's leakage. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. cut tubing to the desired length and bend as necessary for routing to pilot burner. the manual gas control knob is in the ON position. This product was the perfect replacement for the Honeywell thermopile in a circa 1975 gas fireplace unit. Adjustable servo regulator effectively maintains almost constant gas output pressure under wide fluctuation in gas supply pressure. You are using an out of date browser. 0000003926 00000 n Refer to Fig. the robertshaw link gives max lengths vs. gauge. TABLE 8PRESSURE REGULATOR SPECIFICATION PRESSURES IN kPa. Turn the gas control knob counterclockwise. 0000010874 00000 n Safety shutoff or pilot gas proves complete shutdown since the safety shutoff valve permits main burner and pilot gas flow. The ON position allows pilot burner and main burner gas low under control of the thermostat and the two automatic valves. Dont touch any electrical switch or use the phone. Avoid locating gas control where exposure to corrosive chemical fumes or dripping water are likely. If the O-ring is not attached or is missing, do not use the flange. It has been obsolete for over 30 yrs now. 0000052145 00000 n Since these environments can cause the gas control to deteriorate more rapidly, the system should e checked more often. Set your voltmeter for the proper voltage that is, above 24 volts. With the loss of outlet pressure, the second automatic valve closes and is held closed by spring pressure on the diaphragm. When the thermostat calls for heat, the first automatic valve and the second automatic valve operator open. TRADELINE MODELSTRADELINE models are selected and packaged to provide ease of stocking, ease of handling and maximum replacement value. 0000011836 00000 n home heater furnace blower doesn't turn on [SOLVED], Goodman GM880804BNBA ignitor will not stay on. Run pipe or tubing to the gas control. As for the gas valve it is probably a "general controls" valve but any 800 millivolt gas valve can be used as a replacement. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. I tried that once already, but I won't again. Check the regulator setting either with a manometer or by clocking the gas meter. Jumping between the TP/TH and TH does NOT turn the main burner on. Adjust the thermostat several degrees above room temperature. The burner may relight at the full flow rate. As with the millivolt system, you'll be testing a series of components to locate the faulty part. This material is proprietary to Honeywell Limited and shall not be reproduced, copied or used in any manner without prior written consent of . Check the transformer.

Good reading is 0 to 0.2 Ohms . Good info, thanks! The gas valve cannot be repaired in the field. WHEN THE THERMOSTAT CALLS FOR HEATThe gas control allows pilot and main burner gas flow during the thermostat ON cycle, as shown in Fig. When the thermostat calls for heat, the automatic operator valve disc opens. Resistance between THTP & TP must be 10.0 W 0.2 W 0000002119 00000 n Take care when handling the refractory panels as they are fragile until held in place and supported. When the pilot goes out, the thermocouple current drops and the power unit drops out, closing the safety shutoff valve. I show you how to Light the Pilot and Power the Main Burner! The best answers are voted up and rise to the top, Not the answer you're looking for? 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. Regular preventive maintenance is important in applications that place a heavy load on system control such as in the commercial looking and agricultural and industrial industries because: The VR8200, VR4200 gas controls provide 3-position (OFF-PILOT-ON) manual control of gas flow. 0000004689 00000 n Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). If any particular ad is your REASON for blocking ads, please let us know. Failure to follow them could damage the product or cause a hazardous condition. Connect and share knowledge within a single location that is structured and easy to search. If tubing is used, obtain a tube-to-pipe coupling to connect the tubing to the gas control. The pilot stays lit fine and the thermopile generates about 360 millivolts, and there's no problem at the thermostat (checked voltage and shorting past it), but the main valve no longer opens.
