Exhaust and intake for a high efficiency boiler
For those who've had this done or are contemplating it.
If you vent the boiler with PVC pipe through one of your chimney flues, can you have adjacent flues (lined with stainless steel liner) in the same chimney venting your woodburing fireplaces? Or will it get too hot for the PVC pipe?
Also, is there a NYC code for the PVC pipe diameter? Some of the boiler models allow as little as 2" diameter for a 40 ft. run. Is that OK by NYC DOB? Where can I find the info?

Did you think to ask the company that made the unit or the installer?

No, I did not. Thank you for the suggestion.

OP again. Acually finding the answer involved some further research that I did during the course of the day. While looking at the tech manuals for some of the boilers, I discovered that the Vitodens 100 allows you to use stainless steel flexible pipe for the exhaust. For the intake (through a side wall) you can go with PVC or stainless. And the length allowed seems adequate for the height of my building.

MY GOD, don't run a steel pipe for a wood-burning fireplace or stove up along a PVC pipe...UGH!!!
This shouldn't even have arrived at the question stage. But I'm glad that you thought to ask it if you didn't already know.
But again: "UGH!!!"
Please be careful!
BTW Everyone, check to see if PVC is even to code in NYC. I believe it may not be!
Love,

"This shouldn't even have arrived at the question stage."
Wow, what are you now, the question Nazi?
And maybe you should try reading the question properly first, before you comment. It said "adjacent flues". There would have been a layer of brick separating the PVC and the stainless liner for the WBFP.
Maybe your answer should not 'have arrived at the answer stage too.'
