Box for Nuway 4000 stove in Arctic Oven

[@Kimbeattie]

I have the same furnace and have been using it for 5 years for wintering camping I also screw the vent pipe to the top lip on the furnace (small lip that can pull off). I don't have an Artic oven but have a few different tents and we camp down to minus 40. When it gets below -30 we bring the propane cylinder inside the tent. I know it sounds dangerous but we double check every propane connection you need vapor pressure to have heat. I also have a Carbon monoxide detector/ smoke detector, cold weather propane hose, small box for furnace which holds a wood stove fan that goes on top of the furnace and a small battery operated fan/ led light which was designed for ice fishing tent (hang it at top of tent and it blows down heat). I also take a double insulated tarp for the floor. I must admit if we are going for more than 3 nights we take a wood stove someone is then getting up a couple of times to stoke fire during the night.
