On LP installations, use compound resistant to LP gas. If an adapter is used, place the wrench on the adapter rather than on gas control. 0000000016 00000 n If so, then the thermocouple or thermopile is generating enough voltage to keep the safety valve open. The gas control must be manually reset. To ensure proper operation, follow these guidelines: Locate the gas control in the appliance vestibule on the gas manifold. In this HVAC Furnace Video, I go over the Operation and Troubleshooting of a 750 Millivolt Gas Valve and Thermopile/PowerPile. 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. TRADELINE kits include a 9/64 in. Since these environments can cause the gas control to deteriorate more rapidly, the system should e checked more often. PROVIDE DISCONNECT MEANS AND OVERLOAD PROTECTION AS REQUIRED. Adjust the thermostat several degrees higher than your current room temperature. 2, 3 and 11, 12.
