Hi, there is a hand fired boiler I am interested in. It has a 9" flue pipe exiting the boiler. Would it be possible to reduce this and go into an 8" chimney pipe? The chimney will be 8" dia. and 32' high. The chimney would be able to handle the 240,000 (and then some) btu's that the boiler is rated for.
This will be a backup boiler, and will be used in case of power outages, or maintenance, etc....or when I feel like shovelling coal lol.
