Twin liners in one chimney?

[WriteNoob]

If I have one 10x10 tile lined masonry chimney, could I run 2 oval liners, in order to run 2 wood burners in one flue? I'm wanting to run an EPA wood stove, and a ESSE cook stove up my existing stack, like they did, back in the day (1923), when they built the house. Has anyone else done this?

Something about that says "not right" to me, but I'm as curious about the correct answer as you are...

I'm probably off base, but my thinking is that if something like Duraliner solid liner is used, it shouldn't be verboten, as it's zero clearance. I may have to resort to the manufacturer, for a definitive answer, but figured if anyone had done it, successfully, it'd be someone on these forums. The little contact I've had, so far with the local inspectors has pointed toward a, "if the company says yes", kind of answer from them.

We have done two liners in one masonry chimney already.

i dont see why you couldnt do it, with 2 liners theres no way for cross contamination or mixing of exhaust. I do wonder tho if there could be a problem of smoke coming out the liner in use and somehow getting sucked down the one next to it if its not in use. That'd be the only danger i could think of.

Cool. Was it installed professionally, or by a home owner? I'd be looking to do it, myself, if I can.

Was thinking of that, but thought that with at least one in service, and about 18' of chimney inside the heated envelope, I shouldn't have a downdraft problem. Uncharted territory, figuring this sort of thing, as I've not used liners, before. Haven't burned wood since the new EPA rules.

Thanks to all, for the help, by the way. It is appreciated.
