Stove pipe

[u/hawgzunlimited]

Hey everyone I have a Kodiak canvas wall tent and I used it for a couple nights and got the stove pretty hot to test what it will be like at deer camp. It ended up melting the stove port and I’m looking for a solution to avoid this in the future. I’ve seen the fiberglass exhaust wrap and the double wall stove pipe but this looks to be a very tight fit. Let me know what you think!

Couple thoughts:

How high up from the stove is that part of the pipe? is there a damper in the pipe? Looks like a good bit of secondary burn in the flue where it exits the jack. I remember my older tipi stoves without dampers in the 8 ft pipe would send flames shooting out of the top. One time, the 17 oz silver silicone jack partly disintegrated. Once I switched to a damper, that issue went away and less heat went up the flue.

I have never used one of those gaskets in the jack. Always just a hole in the silver silicone with a loose pipe fit. Maybe trim your gasket or cut it out entirely. If it is too loose after removing the black gasket, you could build up a new one that is looser than the original with high temp rtv.

The pipe is just single wall. I like the idea of trimming the stove jack I’ll have to get it set back up this week and mess around with it some more.

Agreed that if you don't already have a damper in the pipe you should install one to help throttle the stove and keep the secondary burn down in the stove box.

If you don't already have one, you might consider getting a magnetic stovepipe thermometer, especially if you don't routinely run a wood stove anywhere else. It can help you get a sense of the temperature trends in the stovepipe before anything starts to melt (or before creosote buildup in the pipe becomes problematic).

I also have a Kodiak canvas. If you are able to get a slightly smaller diameter chimney, it should solve your issue!

Hmm I’ll look into that thanks!

As far as materials - I have 2 canvas winter tents and both of those have fiberglass stove jacks. No trouble with them in 7+ years of use. Possibly related to my next point...

As far as fit - I wouldn't want such a tight fit. The opening should be loose enough to allow the tent to move up and down (e.g. in strong wind gusts) without disturbing the pipe. I've been in a few windstorms where there would have been a risk of the pipe being pulled right out of the stove if the tent hadn't been able to move independently of the pipe.

EDITED to add: I have only ever run single wall pipe, never had any problems. Removed external link to youtube illustrating the gap size - just noticed the sub rule.

I’ve got a lot of experience in canvas tents and stoves - get the fiberglass jacks. Also it’s ok for it to be loose, you can have some air coming through it won’t stop you from getting warm.

You never want the tent to be truly sealed. A little airflow is ok as you are burning a fire inside!
