The Supervent Storm Collar was put around the chimney according to instructions, and even with the screw turned all the way, there is a little gap between the collar and the chimney. I filled it well with a gray high temp caulk from Lowes. But days later, that caulk is cracked and not sealing the gap well. I think the collar allows some movement and also I should try a different type of caulk. (more flexible, maybe?) Is this a common problem, and how do folks solve it?

I used the same product on my install two weeks ago and it had held up well through one rain storm and one substantial snow event.

Clean the oil off the pipe with rubbing alcohol, brake cleaner or similar. Use regular ol silicone, work it in, in both directions(tool it with your finger with some saliva on your finger). The your good to go.

It's normal to have a slight gap on each side of the flue pipe seam. If you feel a need to draw it together a bit, get or make a couple pieces of angle metal, a screw and nut, and attach them above the existing tightening system. You can screw the angles to the collar, it doesn't need to be spot welded.

I had used a high temp silicone tape around the pipe then put the collar on, with the edge cutting into the tape . Perfect seal, all around the pipe , with very little showing . Can't remember where i got it.
The #1 failure that I see with caulking, is when it didn't get tooled. Like most people are afraid to touch it. I don't get it.

Exactly. Many think ya just pump it on and it sticks itself to the surface.
What we realize is it must be tooled in, ensuring it is pressed into and adhered to the pores of the surface it is being applied.
Make all the difference though.
