Flue Damper on double-wall chimney pipe??

[ergeorge2000]

I'm connecting a woodstove to a DuraVent triple-wall chimney using the double wall duravent pipe from the stove to the thimble in the ceiling.

But nothing in the instruct, pictures, etc makes any mention 9of where/how to install a flue damper in this pipe. You know ... the handle on the pipe you turn to control the draft through the chimney. Do I just drill it like normal single wall pipe? Is there some sort of adaptor section for this? Of course the dealer I bought it from is closed on Sundays :/ Thanks Eric

Probably because it is required by code in many jurisdictions.

Why are you using insulated pipe between the stove & ceiling when you can get lots of free heat from an uninsulated single wall section?

[ergeorge2000]

You need 18" clearance from single-wall pipe, and I don't have it. Only need 6" with the double wall.

Sometimes you can put up a metal section and still meet code with a single wall.

No-one seems to have answered your question. The answer AFAIK is you do not use a flue damper with an airtight stove, you control the draft with the stove controls. Your stove is almost assuredly an airtight.
