Exhaust and intake for a high efficiency boiler

Categories: Heating

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?
