The gas valve is the load.need to have current flow from one leg of the thermopilethrough the limit switch ( zero ohms ) througn the thermostat switch ( approx zero ohms on call for heat) through the coil of the valveand back to the other terminal of the generator. Fig. 10Installing thermocouple to the power unit. Carefully check the main burner light off at the step pressure. Run pipe or tubing to the gas control. Refer to Table 7 or 8 for factory-set nominaloutlet pressures and adjustment ranges. Relight pilot burner and operate the system through one complete cycle to assure all controls operate properly. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems.

I go over how it is Wired, what Voltages you should be reading while the flame is present and the voltages needed for the pilot valve and main gas valve to work correctly. If you smell gas, immediately shut off the manual valve in the gas piping to the appliance or, on LP, at the tank. If something is wrong with the internal components of the gas valve, the gas valve should be replaced. Using Kolmogorov complexity to measure difficulty of problems?

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. I was trying to use the "MILLIVOLT TROUBLESHOOTING CHART", on page 2 of this . %PDF-1.5

The maximum regulated capacity is 200 feet 3 /hour [5.7 meters 3 /hour]. Do not bend tubing at gas control or pilot burner after compression fitting has been tightened, as this may result in a gas leakage at the connection. Set thermostat to the desired temperature. At least having yours done professionally would appear to put you in a position of a tax deduction for repairing it. Order number, SUPER TRADELINE or TRADELINE if desired. The best answers are voted up and rise to the top, Not the answer you're looking for?

Gas control operation is described in more detail below.VALVE POSITION DURING THERMOSTAT OFFCYCLEThe valve is positioned as shown in Fig. Ensure the main burner lights smoothly and without a flashback to the orifice and that all ports remain lit. Do NOT use Teflon tape. Since these environments can cause the gas control to deteriorate more rapidly, the system should e checked more often. With the main burner in operation, paint all pipe joints (including adapters) and gas control inlet and outlet with rich soap and water solution. Otherwise, take the necessary steps to provide proper gas pressure to the gas control. Making statements based on opinion; back them up with references or personal experience.
