I'm second guessing my double wall install!

[Hunker Down]

I swapped out my single wall metal fab stove pipe for double wall. I did this because I installed it to close to combustibles. And thanks to everyone on this site they pointed me in the right direction. I posted some pics on a another thread but wasn't sure if it went through properly.

I had a real difficulty installing the double wall. At the stove top there is no way to secure with the self tapping screws provided and I had to man handle it to get the inner portion to fit.

Secondly, the telescoping inner kept falling down into the large section, and there was not any place again for screws at the seams.

Third, at the support box the screws were no where near long enough to connect the two.

Gravity is what is actually keeping everything together more or less. But i did put a couple of tappers at the seams between the telescoping pieces. And one screw bit just enough at the support box

Do the pics look ok.. I am just second guessing myself

I predrill and use 1" SS screws at the ceiling box. At the slip, just shoot the screws in evenly spaced around the joint.

I was concerned that longer screws would have creosote catch on them. Is that a concern?

s that a concern?

no not really they will collect a little bit of stuff but it wont matter

I'm not sure what you mean by the slip? Is that at the top of the stove? Thanks for your help.

I was referring to the telescoping section. After everything is all lined up, use 3 -1/4" screws to secure the joint.
