I have a small New Yorker AP-U (480?) boiler that is currently vented to a large flu in my house's chimney. I want to install a wood stove in my house and I'd like to use the chimney to vent it, which means the furnace would not be able to use that flue. What options do I have for venting my furnace?
P.S. I have a chimney expert coming to take a look tomorrow. I'm just looking for other opinions.
