Utica boiler Thermocouple problems
Hey guys I'm new to this site so I apologize in advance if my topic has already been posted. I have a 105,000 BTU Utica gas-fired steam boiler that was installed 6 years ago tomorrow. Heres my problem, I fired up my boiler for the first time earlier this month, and noticed that the pilot flame was large and a light orange color. I don't remember the pilot flame being that noticeable. My friend, who has an hvac company with his father said that it wouldn't be a problem but that the thermocouple would need to be changed sooner rather than later. Another friend of mine whose in heating said that the only problem would be that it would use more gas as its feeding a larger pilot flame But later on in the night I noticed that the boiler was cycling on and off in a matter of about a minute. The low water cutoff light would start blinking, as if there was no water, and then reset, then the boiler would start up as if to heat the house but only for a few seconds, then it would click off again, And then repeat. I called a local hvac company for a troubleshoot house call, and they also noticed the intensity of the pilot flame and the only thing they said was that the gas valve needed to be replaced. My question to anyone that can help is, could a faulty thermocouple cause the symptoms I described? If not, what are the signs of a faulty thermocouple? Is it safe to have such an intense pilot flame?
Thanks for your help.
