Extending stack upwards

[Salcombe Woodsmoke BBQ]

Hi all
Me and a friend built a shelter for my landmann 400 (it's my current profile pic). Next I want to extend the stack through the roof. It would be about 4ft and a 4" diameter. Does anyone have any opinions on how this would effect things? Would it cause the smoke to stall at that length. I welcome all info. Thanks

Should be fine, heat rises once the natural convection of heat begins.

With a chimney on a house it needs to be above the highest roof height not sure this would apply to your smoker.

This is my thoughts also. However, people have told me that smoke can stall in overly long stacks. I think they're talking about 8ft plus though? I'm hoping this wont be an issue with a 4ft extension?
Thanks for your input.

I think if the smoke cools too much in the long chimney it will stall. I would pull the smoker out of enclosure. Get the length you need of single wall stove pipe at Home depot and put it on your smoker and then try it at your cooking temps.

That's a really good idea! Weather allowing I'll give it a go this weekend. I'm in the UK so Screwfix not Home Depot, haha.
Thanks for the advice, buddy.
