Natural to LP gas conversion kit included with TRADELINE standard and slow-opening models. The rod, which should be cleaned annually, by the way, will heat up and send a millivolt signal down to its ceramic base and on to the control board. 10. For a better experience, please enable JavaScript in your browser before proceeding. If the regulator cannot be adjusted and supply pressure is in the normal range, replace the gas control. Paint all pipe connections upstream of the gas control with a rich soap and water solution. pressure drop for straight-through configuration). 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. As for the gas valve it is probably a "general controls" valve but any 800 millivolt gas valve can be used as a replacement. Assure the main gas supply valve is open and the pilot gas supply line is purged of air. 0000011836 00000 n This valve is only for vent free applications. WHEN THE THERMOSTAT CALLS FOR HEATThe gas control allows pilot and main burner gas flow during the thermostat ON cycle, as shown in Fig. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. You should NOT short out the t'stat terminals to check it.

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. Furnace gas valves cannot be repaired. SIT 822 Valve with a Honeywell Electronic Igniter NOTE: Remove glass before servicing. See Fig. The Robertshaw - Uni-Line 700-500 and 710-500 Series millivolt gas valves are thermostatically actuated com- bination gas valves.
