Kit for conversion from LP to natural gas is available for standard and slow opening models. The electrical/scientific basis for millivolt systems is the Seebeck The pilot stays lit fine and the thermopile generates about 360 millivolts, and there's no problem at the thermostat (checked voltage and shorting past it), but the main valve no longer opens. It does so for the very first instance both in the morning and night but thereafter, the pilot just stays lit and the chambers aren't lit or heating the house. Also, this product is tested and calibrated under closely controlled conditions, and some minor differences in performance can be expected if those conditions are changed.

The gas control knob is hard to turn or push down, or it fails to pop back up when released. Exposure to water, dirt, chemicals, and heat can damage the gas control and shut down the control system. Turn off the gas supply valve to your appliance to test whether your valve is capable of shutting down properly. Zero clearance sleeve is required only for combustible walls. Filter. If outlet pressure begins to rise, the pressure regulator the diaphragm moves slightly higher, allowing less gas flow to the gas control outlet. Always replace the cover screw after adjustment and tighten firmly to assure proper operation. 0000068110 00000 n
If pilot burner flame still goes out, measure the open and closed thermocouple output voltage. 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. 0000006677 00000 n
