Hissing sound after boiler shuts off...
Been a while, but I think I may have an issue with my boiler and wanted to get some feedback.
I drained my converted gravity system a week ago to have a radiator removed due to a bathroom remodel. While it was emptied I also had a Caleffi air separator installed. Bathroom was completed earlier this week, the radiator was reattached, and the system was filled. I bled all the radiators from the top down and fired up the system to get the fresh water circulated through it. The system ran for about 15 minutes and then I shut it off. Once off, I heard something hissing which I thought was coming from the air separator, but it was coming from inside the boiler case.
So..My question to you experts and Pros: How\What can I check to see what the cause is?
