Dendrobatty Posted August 7, 2019 Share Posted August 7, 2019 Hi, I have a Landmann Vinson 200 and am wanting to locate it under a roof/shelter. My plan is to extend the flue so that it will pass through the roof. Has anyone extended a flue and if so do you have and tips/hints/guidance? I was considering having a flue with a damper in to give me a little bit of control over the draw. Again any observations/guidance gratefully received! Thanks!

Icefever Posted August 7, 2019 Share Posted August 7, 2019 It shouldn't be too hard to add a section, but why go through the roof?? through the wall and it's easier to seal. Just my 2 cents mate. Ice. Quote Link to comment Share on other sites More sharing options...
Dendrobatty Posted August 7, 2019 Author Share Posted August 7, 2019 Sorry, my poor explanation, it will essentially just be a roof on stilts, just to keep the worst of the weather off. Quote Link to comment Share on other sites More sharing options...
Icefever Posted August 8, 2019 Share Posted August 8, 2019 Ok, got the picture now...then no problem, you should be able to find the size of pipe off of the net....not sure how to fix a damper in-line??..fitting on the top could put it out of reach. You could try making a butterfly type, like on a carb?? short section of tube, cut a disc to fit inside then weld/fix to a bar running through the pipe?? then open/close when needed....that should work.

Nige Posted May 8, 2020 Share Posted May 8, 2020 (edited) There are some considerations, a longer flue creates more draw, also takes a bit longer to heat up to create that draw. If its long enough the gasses cool before they leave it causes condensation to run back down. Probably better to fit a pipe in the roof with a funnel type end to it for the smoke to filter in an up. But ultimately if its open all four sides the wind will carry the smoke away with out any extensions etc. Edited May 8, 2020 by Nige Quote Link to comment Share on other sites More sharing options...
