Hello, I recently bought a reconditioned Chubby Sr. from Larry Trainer at Chubby Stove Co. The stove is a blower model and it is like brand new ! The work done by Larry is first class in every way, and he's great person, full of story's and information about these stoves. My question that I need help with here is, where my installation is going to be on a fireplace hearth' venting into the masonry chimney through my fireplace. My problem is that the six inch stove pipe is two large to fit through the throat of my chimney. So I have the option of closing off the fireplace and venting directly into the fireplace, but I understand that this type of installation reduces the draft. So I have two questions, would it be better to have fabricated some kind if sheet metal closure at the throat with a six inch rectangular opening and just venting into the fireplace or can I reduce the size of the pipe so it will fit through the throat and run the pipe up the chimney ?? Which way would I have the best draft ?? or any other suggestions out there would be welcomed.
