Hello all!
I have a banging noise coming from my boiler when the burner reaches a certain temperature. I'm almost certain it is air in the system and have a few questions concerning what should be done.
First off let me give a bit of the backstory. I tore out my bathroom in November of 2008 to do a complete remodel and removed the cast iron baseboard that was there. As of now, a new radiator has not been installed. I did install new lines that are capped.
If air was trapped in that either the supply or return line (I'm sure there is) could that be making it's way back to the boiler?
Each radiator's supply and return go directly to the trunk line in the basement.
If that would effect the air in the whole system, can I get it out temporarily. I've ordered a Runtal radiator but it has yet to arrrive.
It's a Bryant system that is about 10 years old.
Thanks in advace for all the info.
Best Regards.
Jef
