Thick wall through wall help

[corydupuis]

Im replacing a brick chimney .i have a opening but my wall is 18inches thick. Can i use a 24 inch piece of duravent to replace the 9 inch length that comes with the thimble to get my desired length?

Yes, as long as the 24" DuraVent pipe is their class A chimney pipe that matches the tee chimney pipe type (DuraPlus or DuraTech). And a proper wall thimble is used to maintain the required clearance.

Thanks,im planning to using double wall stove pipe to connect to the chimney pipe ,do i need a separate adapter to connect the two? Doest the chimney pipe have a thimble end designed for single wall?

Stovepipe is not permitted to pass thru a wall. It has an entirely different and much higher clearance requirement.
Duravent makes an adapter to attach single or double-wall stove pipe to the female end of the chimney pipe. 6DT-FC

Assuming this is a traditional masonry wall, at that thickness?

No comment on the chimney product selection, @begreen knows way more about that than me. But speaking as someone who deals with old houses and metals in sometimes-corrosive environments, the age and type of masonry will dictate the concentration of salts and moisture to which this thimble is exposed, which could have lifetime implications. If very old (pre-Portland cement era) masonry, I'd be checking materials used on each option, and selecting 316 stainless outer over 304, if available. Both will work for some period of time much longer than any coated steel, but 316 is superior to more common 304 in any application exposed to salt and water.

Stove connection thimbles in old masonry walls used to be heavily-glazed terracotta, of which I have maybe a half dozen (all unused) in my house, but all indoor-only transitions between a room and a masonry chimney. I don't think they'd hold up well to weather, if penetrating the wall to outside, nor do I know if there's even an approved version of them available for today's chimney systems.

A picture or two would be good. I am assuming the additional depth is due to the chimney removal, but there may be other factors involved here depending on the wall construction. Some visual cues would be helpful.

The thickness has to do with it being a old log cabin. I removed the masonry chimney that was here and am running a through wall to an already existing through ceiling hole that the previous chimney went through.

Got it. This is a combustible opening. The thru-wall connection must be done with class A chimney pipe as an extension off of the tee snout.

New problem, i cant figure out how this wall mount works. Its a supervent..i looks like it just sits on the mounting plate but then if you wanna take the cap out you have to remove the wall support..? Im confused
