Do not thread pipe too far. The gas control should e replaced if: It does not perform properly on checkout or troubleshooting. When the thermostat calls for heat, the first automatic valve and the second automatic valve operator open. If it is flowing, measure the voltage between the 24V Hot and 24V Common leads to the SmartValve. Never use any tools. 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. Your problem seems to involve large -- really large -- "industrial size" issues. The reduced pressure on the bottom of the automatic valve diaphragm repositions the diaphragm downward away from the valve seat, allowing main burner gas flow. The pilot light is auto so when the thermostat calls for heat, a spark is sent to the ignition lighting up the pilot. Does that indicate more a gas valve problem or a thermopile generator/pilot flame problem? 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. It has been obsolete for over 30 yrs now. The OFF position prevents pilot and main burner gas flow. Continue to hold down the reset button for about one minute after the pilot is lit. trailer Lv 4. On LP installations, use compound resistant to LP gas. Models for natural or LP gas. .
