Hello all,
Thank you in advance for the helps and tips.
We replaced the oil steam boiler in September of 2018 with a gas boiler, it was working fine last year however this year I have run into major issues with the new boiler.
From what I can see the pressuretrol does not turn off/ turn/on the boiler when it hit the max/min pressures limit.
The boiler will turn on when the Tstat call for heat and run for about 5 minutes and then off 3 minutes and on/off again until temperature reach what the Tstat set or until pressure in the boiler reach to a point that is open the relief valve.
The pressure usually does not get that high unless I set the temperature on the Tstat to 72 or above.
When the temperature set to 68 the boiler usually shut off at around 5psi according to the 30 psi gauge that the boiler came with.
After reading through many discussions on this forum and others, I believe this could cause by a clogged pigtail or a bad pressuretrol.
It seem like I need to take off everything around the pressuretrol before I can take the pigtail and the pressuretrol out of the boiler.
I have attached a picture of the boiler setup and looking for helps to see what the best thing to do since we in the middle of winter and don't want the house not to have heat for too long.
Thank you for all your helps in advance.
