I do love these furnaces. I ran this in my topper for weekend trips and ran it solely off a small 20000 mah batt pack and never fullydepleted it.
That's a nice furnace. Even with the fan, it will be a very low current draw from the battery.
Sealing up my chimney pass through. Do you guys think butyle tape on the outside baffle would hold up to a little heat? Im not familiar with using that stuff. Otherwise was just going to caulk it in.
