I'm no authority, not even close, but I've been reading up on this because I have a similar problem with my home system so this vid caught my interest. If I understand the theory correctly, it seems to me that any leak around the damper *increases* the volume of air going into the stack and should act to *reduce* draft. Effectively, its like using a bigger damper. I can see where it might be a problem if you had too little draft, but then there probably would not have been a need for the damper to begin with. Or am I just missing something obvious? I'm guessing that's why the installer didn't bother to create a better seal though it doesn't seem like a particularly good idea to deliberately create a leaky chimney, so probably not deliberate.

I like what you thinking but isn't b vent on each end of each fitting machine pressed or at least one side I would think there wouldn't be that much infiltration unless it's an adjustable piece

you seem right.

Interesting observation. I’ll buy it.

I've never a seen a barometric not make a huge difference. It's all I can come up with. They make expanding foam rated at 1000F, might give that a go

Did the high temp foam make a difference in the draft?

Stuff something in that gap.

What is the fuel type ? Fuel oil ? Coal ? Natural Gas ? LP ?

Natural Gas

@@MrBerniebling the draft diverted keeps the draft constant no matter what the pressure is outside, ex. Windy and cold to warm and mild. It allows the heat to be absorbed by the water in the boiler. If you try to run an oil burner without it you get nearly zero heat transfer to the water. If it was forced air it still won't make heat even if it's burning.
