It is b-vented in an old fireplace chimney. Previous company had busted out block to bring in basement. No i personally did not verify venting with an analyzer, pm techs do that on the tune ups. Its been sitting there for two years now and from what i understand its fine. Wouldve had to change if not.Sometimes our techs find issues like that and we always repair
[QUOTE=gravity;13111991]with your boiler;
- pumping into expansion tank...not good.
- pump is on return side...should be on supply and pumping away from expansion tank
thats from pumping away - Dan holohan thats cool people actually read his stuff. (-: The pump is always installed after the expansion tank because of the 0 pressure change. highly recommend the book.
he even says in his book that a lot of boiler manufactures say to put it in the return, which is incorrect.
