Thanks for the helpful information

So should I just add more insulated piping on to it. Possibly secure it to the roof with metal ties?

Here's some photos

Hi! I have an off grid homestead in northeastern Minnesota. I just finished building rocket mass heater core and all the piping. Due to building design heater is under the lowest slope of the building. Hence chimney being 4 ft. under the peak of the building. I just test fired it and was drafting beautifully. Though it is August, I'm worried about possible issues in the winter. Thanks for any information
