Venting Installer Question - Can I Use One Trade?
We will be replacing our existing over sized boiler with a new higher efficiency boiler and want to reuse out existing chimney flue to vent the exhaust. Since the new boiler will produce lower exhaust temps, it was recommended that we use a 4" liner for the existing flue with 4" B-vent between the boiler and chimney. Can a heating contractor/plumber do the new liner and associated duct work install, or would I need a chimney sweep to do that work and get separate pricing? It would be nice to have one trade involved so that if any future problems occur, the original installer can rectify them.
Thanks in advance.
