Woodstove stack thru cathedral ceiling
PatchogPhil
| Posted in Energy, Heating & Insulation on
Looking for proper way to bring smokepipe from a woodstove thru a cathedral ceiling. Smokepipe is 8″ diameter. The walls behind stove and the ceiling are finished inside with tongue and groove pine planking. Roofing is asphalt shingles. Location is Deposit New York.
Was told that cement-filled smokepipe is supposed to be used (approx. $130 per 3ft section), which makes the 18 feet kinda expensive. Don’t really want to punch thru the side wall as there is a very deep overhang from roof even on the gable ends.
What are other code-approved types of stack material that can be used?
Any other tips and info appreciated.
TIA, Phil

patchogue.... dat u ?
everything from the wood stove to about 18" below the ceiling can be single wall stove pipe.. you can use a cathedral ceiling double-wall hanger at the ceiling to support the rest of the pipe from there up..
then the flashings, braces, and cap
so... how goes the cellulose wars ?
piffen posted a wood stove check list a while ago.. was pretty inclusive

Hey Mike
Cellulose has my house warm and quiet.
Wish I could find the stovepipe checklist. Maybe I haven't used the search feature the correct way?

I don't think we really covereed the Q you're asking. A box with a hole in the bottom is the ceiling support unit for cathedral ceilings. You cut a hole through the ceiling equivalent to the sillouette it fits through and nail it in place throughthe sides of the box, makling darn sure that it is level on the bottom because this is what supports the rest of the insulated stack up outside. The insulated pipe goes up, a roof flange surronds it, correctly inserted under shingles, and usually a brace bracket if on a steep roof, then the rain cap. Use some good caulk to seat the rain collar over the roof jack. This metal is likely to move a lot with thermal expansion and break seals. Silicone or geocel sealing it to the pipe and not to the roof flange should keep most of the rain from running down the pipe.
In cathedral ceilings, these things are notorious for attracting condensation that appears as leaks.
