Manfred showed an interest in making his HMG Ultamid-4 hot tent compatible, and rather than clog his nice trip report up with this unrelated stuff, I figured I’d start a new thread for hot tent conversion.
For the HMG I would suggest the following. Cut the margins of one vent clear from the tent body (the blue line; only the vent panel itself) and leave it attached at the apex. This way it might still be used to cover the stove pipe hole when you aren’t running the stove. The flap would have to be well secured when running the stove since Cuben melts enthusiastically (red arrow).

Most stove jacks are overly complicated and overly engineered in my opinion. This Lone Peak has a modular stove jack that velcros into a hole in the tent and can be replaced by a solid fabric panel when not being used as a hot tent. That extra flap of jack material acts as a rain gutter when the pipe is inserted. Nice, but not that necessary. All the grosgrain edge binding make the design look nice, but is not needed. A bead of Aquaseal along the edge would make a nice selvage and seam seal the jack edges too.

This is the jack in my SO Redcliff. The top and bottom velcro tabs allow you to roll the cover flap up and act as a rain gutter. The side velcro flaps hold the cover down when not being used as a hot tent. Making the flap out of jack material basically doubles the amount of that relatively heavy material. The Lone Peak strategy is lighter and less bulky.

This is the inside. Installation is easiest if you lay the tent panel on a flat surface, position the jack in place and pin it well, sew it on, and then at the very end cut the hole in the tent fabric. That way you can make sure the jack is smoothly covering the part of the shelter it will be replacing.

Since the hole in the jack is supporting all the lateral forces on the pipe it can get pretty beat up in the wind. I like to add a cable ring to help distribute the forces.

This is the jack I added to my MLD Supermid. I think it came from TiGoat (don’t remember). It has a removable flap cover held in place by velcro. All the layers of velcro and edge binding make it kind of bulky. Also, the hook side of the velcro is on the jack, not the flap. If you leave the flap at home the hook velcro can be damaging to the tent fabrics it comes in contact with. This seems like a design mistake to me.
