Nice!At a local deer hunting camp, the install had not met CTC. This included the single wall stove pipe.
Wanna know how it was addressed?
Nothing more than a length of aluminum foil hung behind the pipe and stove. Been like that for years! Would I do that in a house for full time burning? Ha! But, you can't argue with success; it works well and costs less than a buck! (see what I did there? Deer camp....less than a buck? Aw, forget it!)
