New to the forum, been lurking for a while, lots of good info here. Just put in a Clayton wood furnace and I think I'm gonna build a boiler similar to a Garn. I've heated with wood for twenty years and was in the HVAC bidness for years, but I've been out of it for so long I no longer have any hookups on equipment. I'm need to find a draft inducer for a boiler with around a 1/2 to 3/4 hp motor and a 4-6" inlet. Anyone have any ideas?
