We might be able to do something about it. VR8200J has a six-second delay from when the thermostat calls for heat until the main gas valve opens. Draw yourself the circuit. The small valve seat attached to the reset button closes and shuts off the pilot gas flow. 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. See Accessories.CAPACITY: 130 feet 3 /hour [4.2 meters 3 /hour]. Solenoid-operated first automatic valve opens on thermostat call for heat and closes when the call for heat ends. Readjust the full rate outlet pressure if necessary to improve light off characteristics. 2). The minimumregulated capacity is 40 feet 3 /hour for propane. Fig. If it goes out, repeat steps 36. Do NOT use Teflon tape. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. 9.

A contractor came by and gave it a crack at it and said it was the gas valve but I'm not confident that that could be the problem as from reading this post, the thermoCOUPLE should be swapped out first before assuming it is the gas valve as it is a more pricey unit to replace. The second automatic valve operator is de- energized, closing the channel to the pressure regulator, and opening a channel to the underside of the second automatic valve diaphragm. Because gas is involved, problems with gas valves are a major safety concern. . The ON position allows pilot burner and main burner gas low under control of the thermostat and the two automatic valves. Replace the thermocouple if voltages are outside the acceptable range. The pilot light is auto so when the thermostat calls for heat, a spark is sent to the ignition lighting up the pilot.
