Help? Unable to light pilot on boiler
From the dataplate -
The H.B. Smith Co, Inc
Series G200
Boiler Model Number G200-W-4 CON
Serial J80-2567
Input BTU 112,500
Output BTU 90,000
Type of Gas NAT
Went to light the pilot yesterday evening. At the pressure regulator, turned it from Off to Pilot, and depressed the knob.
Took my long lighter, and lit the pilot. There it was, burning happily blue, when it flickered and went out.
Tried to relight it, and nothing. Went outside, made sure the gas was on out there, it is. Checked the on/off valve by the boiler, it's good. Ran through the light off process again, nothing.
Let it sit over night (regulator in the OFF position) and tried it again this morning. Nothing. Pressed and held the pilot knob in for a couple minutes and listened and sniffed - no slight hiss of gas escaping, no smell of gas, nothing.
What I'm thinking at this point, the regulator has failed. There's no click of the valve when I press the pilot knob in - there used to be a firm click when you pushed it in. You could also hear the gas hissing from the pilot, and if you didn't move fast, you'd smell it too. I'm assuming that as a safety feature, if the device is going to fail, it's going to fail in a closed position.
Electric cables to two spade connectors are in place, I've checked their connection in the junction box by the pump, they appear solid there. If I turn the thermostat to 75, the pump motor starts to turn.
Any further suggestions for trouble shooting - and any idea on what I'm looking at to replace this part? I'm going to assume that this isn't something I should try to replace myself since it's connect to the natural gas line.
Any assistance will be appreciated.
Thanks
