Do not exceed the input rating stamped on the appliance nameplate or manufacturer-recommended burner orifice pressure for the size orifice(s) used. Ensure the ambient temperature does not exceed the ambient temperature ratings for each component. Then the regulator valve is forced fully open by the timing diaphragm, which is operated by bleed gas. Check the ratings given in the instructions and on the product to ensure the product is suitable for your application. %PDF-1.5

Both pilot and main burner are shut off. 15. 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. The next time the valve fails to open you need to measure the voltage across this valve coil, or, better, the current through it.. What gauge number wire and what length do you use to your t'stat?

Do not make sharp bends or deform the tubing. There must be two terminals in this connector block that powers the gas valve coil. This shuts off the pilot and main burner gas flow. This type of gas valve used a single thermocouple. This increases gas pressure under the automatic valve and repositions the valve disc closer to the seat. ny outlet pressure change is immediately reflected back to the pressure regulator diaphragm, which repositions to change the flow rate through the regulator valve and, thus, through the diaphragm-operated automatic valve. Is it correct to use "the" before "materials used in making buildings are"? SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION. In replacement applications, locate the gas control in the same location as the old gas control. Place gas control knob in PILOT position. LP to natural gas conversion kit available for standard and slow-opening models. If the switches are good, that sort of defaults to a bad gas valve. If the regulator cannot be adjusted and supply pressure is in the normal range, replace the gas control. Stand clear while lighting the main burner to prevent injury caused by hidden gas leaks, which could cause flashbacks in the appliance vestibule. After the adapter is installed, the gas control is attached to the adapter as outlined above. This is an electrical connection and must be clean and dry. 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. 0000005594 00000 n
What sort of strategies would a medieval military use against a fantasy giant? This valve is only for vent free applications. This material is proprietary to Honeywell Limited and shall not be reproduced, copied or used in any manner without prior written consent of .

Check fireplace to make sure it is levelled and properly positioned. Tighten only 1/4 turn beyond finger tight to give good electrical continuity. 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. If necessary, adjust the pressure regulator to match the appliance rating. 4 41
I'll show you how to troubleshoot and diagnose the problem with your water heater and Honeywell gas val. Push in firmly to lock in place. Pilot gas flows through a port in the ushing around the reset button shaft to the pilot burner. Set the thermostat to the lowest setting and shut off the electric power to the appliance. If necessary, adjust the pressure regulator to match the appliance rating. Exposure to water, dirt, chemicals, and heat can damage the gas control and shut down the control system. The Robertshaw - Uni-Line 700-500 and 710-500 Series millivolt gas valves are thermostatically actuated com- bination gas valves. If outlet pressure begins to fall, the pressure regulator diaphragm moves slightly lower allowing ore to flow to the gas control outlet. Any help and/or comment would be greatly appreciated. When the pilot goes out or becomes too small to sustain normal ignition. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. If above 11 ohms, replace the gas control. A place where magic is studied and practiced? 0000098789 00000 n
Why isn't the spark gap lighting the pilot on my furnace? . Remove seal over gas control inlet or outlet.
