My dad and I are both getting the Woodstock Progress, hopefully soon. I think I all set in my setup, but since we will be installing both stoves together, I'd thought I'd get some opinions on my dad's setup.
He will be rear venting into a 25-foot (from stove to top), interior, 7X11", clay lined masonry chimney. I suspect he will want to line this chimney, but one of the folks at Woodstock told him they would try it first as is. So, he is leaning towards holding off on the liner.
He will be rear venting straight into the chimney. Currently, he has an 8" pipe out of the chimney. While it would be easy to simply put a reducer there for the 6" exhaust, there is a slight problem. The center of the 8" pipe is about 27" above the hearth. The Progress has a 27.75" exhaust height. So the center of the pipe is about an inch low. What I'm thinking is if a 6" pipe was placed at the top of the existing 8" hole, we'd have a perfect height (i.e. no chimney cutting require). Ok, so here are some questions:
1. If he decided to just go ahead and line the chimney now, the snout could be situated at the top of the 8" hole and the exhaust height issue goes away. If a liner is recommended, what size? A 6" may not fit. I've read that tall, 5.5" liners can draft too well. Oval is significantly more expensive. Also, the stove is on the first floor but the chimney extends through the basement with a clean out door. Do you need to line all the way to the basement, or just terminate with a tee at the stove? Being an interior chimney in good shape, I don't think insulation is required. Maybe just pack some around the top to keep the portion above the roof a bit warmer?
2. If he decides to hold off on the liner, how do we adjust for the exhaust height? Could we simply mortar in a piece of 6" pipe (maybe stainless) at the top of the existing 8" pipe or hole? I assume there is a clay crock in the 8" hole, but the short piece of 8" pipe that comes out of the chimney is fixed somehow.
Thanks!
