ADJUST THE PILOT BURNER FLAMEThe pilot flame should envelop 3/8 to 1/2 in. Using Kolmogorov complexity to measure difficulty of problems? If the inlet pressure is in the normal range (refer to Table 7 or 8), replace the existing gas control. This wiring should reduce to a simple series circuit: a gas valve coil in series with a thermopile in series with a t'stat with normally open contacts in series with a limit switch with normally closed contacts. The internal valve coil must then be connected to the topmost and bottommost of the four terminals. Set your voltmeter for the proper voltage that is, above 24 volts. Thanks for contributing an answer to Home Improvement Stack Exchange! 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. 10 0 obj
