I have a Crown CSC 150 boiler with powered exhaust. The 3" exhaust is direct-vented through the wall and can be heard from several houses away. I am looking for a solution in the form of an enclosure, silencer or muffler that will help mitigate the noise and not restrict the exhaust flow from the boiler. Thanks in advance for your insight or thoughts on this issue.
