vtfireman85 Posted April 11, 2022 Share Posted April 11, 2022 I have a 4 flue 7x11 chimney. The one i use for the woodstove has a liner which is nothing but a creosote trap. I think I could break the tiles out down to the thimble and replace them if i could find self aligning tiles. I can find them in round, but not in rectangular. Any suggestions?

[search on line] Mike The liner it has now is stainless, the integrity is fine, but it’s like flexible exhaust pipe. Where a clay liner is sort of like a cast iron pan, naturally seasoned and non stick the stainless with all the ribs just collects creosote. Never had an issue with the same Stove and a metalbestos chimney, nor an issue with the same one and a masonry chimney. This liner is a nightmare.

TomH Posted April 12, 2022 Share Posted April 12, 2022 DuraVent 6DLR-36O 6" Inner Diameter - DuraLiner | Build.com This might work, but it looks like its pretty expensive depending on how much you need. Perhaps it is possible to use both with the smooth liner in the lower portion. Quote Link to comment Share on other sites More sharing options...

I should have clarified that. My flue size is 7x11 interior rectangular. My stove requires 8”round or larger. Soni need at least 50 square inch in cross section.

jeeper61 Posted April 12, 2022 Share Posted April 12, 2022 Why was the existing flue lined? If you can get the ridged stainless liner in there that is the way to go But some off old masonry stuff isn't a straight shot it An alternative to that is smooth wall flexible Quote Link to comment Share on other sites More sharing options...
jeeper61 Posted April 12, 2022 Share Posted April 12, 2022 Here is a link to the Duravent catalog they have some oval products https://duravent.wpengine.com/wp-content/uploads/2020/06/DL_L820_03-24-20.pdf 1 Quote Link to comment Share on other sites More sharing options...
midnightman Posted April 13, 2022 Share Posted April 13, 2022 Custom formed rectangular sections of stainless sheet. Weld them together as you drop them in? Might seem too easy for me as I have the equipment to do it. Quote Link to comment Share on other sites More sharing options...

Exactly what I was thinking. Don’t think it would be that bad to back purge. Tape some dams in on either side of the joint. 1st hot fire would clean it out.🤷♂️ 1 Quote Link to comment Share on other sites More sharing options...

russ_alabama Posted April 13, 2022 Share Posted April 13, 2022 Don't know if these guys would have what you are wanting, but I bought round 6" single wall thick stainless liners to put inside my busted up clay liner from them. https://www.rockfordchimneysupply.com/ My new Legacy coal stove (that I'll burn wood in) that I replaced the old Ashley with had 6" for the pipe, so that worked out for me. They have very good technicians that know the products and installation methods for advice. Also, look at the custom shop tab. Can't tell you it works great as my builder's not come back to finish up yet. Dad's chimney sweep brush was a couple of old tire chains tied up in a wad on the end of a 20ft log chain. Might have been less gentle than what'd have been ideal, but it was fast and Dad hated two things: caution and delay. Good guy though. But he had one busted up liner down in the bottom of the chimney. 1 Quote Link to comment Share on other sites More sharing options...
snoshoe Posted April 13, 2022 Share Posted April 13, 2022 Don't have answer to question. Do have some thoughts. The present liner is plugging because the ribs are cooling the flue gas causing the creosote to condense. Is there room between present liner and chimney to pour insulation such as vermiculite in to keep heat in chimney? Had similar problem with masonry chimney. Would grow feathers at tile joints. Cure was to replace electric draft control on stove with combustion fan. The hot fire when it called for heat cleared the chimney. Quote Link to comment Share on other sites More sharing options...
460 Posted April 13, 2022 Share Posted April 13, 2022 Depending on location there was companies doing a sealed coating like a ceramic on the existing tile/wall. Seemed to be more popular in the North Eastern US when I researched it. A smaller diameter round liner can actually have more draw then your current rectangular.

int 504 Posted April 14, 2022 Share Posted April 14, 2022 As far as welding stainless goes, it can be done with a dc welder and the correct rods. No shielding gas required. Quote Link to comment Share on other sites More sharing options...
