Question about Hayward 150000 BTU Millivolt Natural Gas Heater
Had pilot generator replaced and also replaced gas valve. Pilot flame is strong ,gas pressure good. Am i wrong in thinking that the control circuit is not a part of the pilot staying lit. Was thinking a wire could be grounding out shuting down valve so i disconnected all wires from gas valve leaving just the generator wires connected pilot goes out as soon as i release button,by the way i also tried another new pilot generator same results. Does any one have any ideas?
Are you certain you are connecting the generator to the correct terminals? Is the pilot head partially blocked not allowing the flame to reach the generator even though the pilot is lit? Can you read the millivolts on the generator leads? Is the reading 400mV or higher? I assume it will be with a new generator but if it is not then the flame is not across the generator as it should be. If it is, be certain you are connecting the two leads properly and in the correct order. The generator has polarity so it needs to be connected to the valve properly. The tag up inside the heater should give you the correct locations for the white and red wires on the valve.
