WeilMclain SGO5 steam boiler turning on and off often.....Need Advice
I have a customer that I just serviced.....while I replaced the nfs and got the unit running, she had told me her boiler was never turning off. I ran the unit to see that 3 of her radiator vents just kept letting out steam so I replaced them. One of the radiators was banging so, I had lifted the pipe and radiator so that it had pitch. I thought I had done well, but then a day later she was complaining that she can not sleep at night as it turns on and off often. I saw for myself that it gained pressure 3 lbs. within 10 minutes, then turned off and turned back again quickly, within 5 minutes. The customer has all the radiators off on the third floor as she does not use them so this boiler is only supplying 5 radaitors on first floor. I was told by someone who has been in the business a long time to down fire the boiler as it is a 5 section boiler and it is designed to heat the whole house and all radiators. It burns with a QB 180 oil burner with a 1.10 at 150 psi. so I'm pretty sure that would be about 1.25. It calls for 1.45 max. I'm kinda confused.....maybe I'm second guessing myself.
