Even down -40 below that wood stove would heat that tent with no problem.
With hardwood you would still have coals in 8 hours.
Your better of with a 4" flue opening.
The standerd pipe on the 2DX goes from 5" down to 4".
You would need one more length of 4" pipe in addtion to the standard pipe set to meet your needs.
Thanks for asking !
