Looking for feedback on repiping Dunkirk boiler
I am getting ready to repipe a Dunkirk boiler and have a concern with the configuration when I come off of the header. The current configuration has what I think is a bullhead. The riser comes up and across and into a tee. One direction the main continues on and increases from 2" to 2-1/2. it was reduced out of boiler when installed. That main continues about 75' and dumps into a Hoffman #55. The other direction out of the tee it runs 2" for approx. 11' reduces to 1-1/4 to go feed a radiator on the second floor. One question I have is can this feed that runs upstairs be tied right into the header? The pitch is uphill away from boiler and some condensate would have to trickle back into header. I plan on rotating boiler 180deg so you can actually access controls and add a cleanout tee and repipe using 2 risers with original install specs. Also removing watchman condensate pump. I'm adding some pics for illustration.
