This Eurosit gas control valve is particularly for use with most gas hearth related heating applications as well as many other vent-free appliance applications. Gas Leak Test. 9. The thermo coupler has a flat spot on it there is a number that has to match up for it to work and the threads are different. The second electromagnetic valve in the gas valve, the "main" valve, allows gas flow through a much larger tube to the burner trays. Operation. 6. Installing the Valve. Snap and modulating gas valve Thermostatic bellows Pilot gas outlet Thermoelectric Flame failure Pilot outlet with gas flow adjustment screw Main gas inlet and outlet at side or bottom Gas inlet pressure test port no. Make sure pilot flame is engulfing the top 3/8” of the thermocouple. 8. Maintenance. Very often the gas pressure is too low. The 630 sit gas valve is Uro valve made in Italy. no. This kit can be used convert from the discontinued Honeywell system to SIT millivolt valve system. 5. Valve Description. WARNING: BEFORE DOING ANY GAS CONTROL SERVICE WORK, REMOVE GLASS FRONT. This second electromagnetic valve gets power from either a 24 VAC transformer or the thermopile. Gas valves are not serviceable; the following are simple troubleshooting and description of how gas valves operate. Related Manuals for Sit 630 Eurosit. 9.
