3″ RV / Bus Installation Kit – Roof Exit BUNDLE

This kit is for venting 3” stoves like: The Dwarf 3kw LITE, Cubic-Mini Cub & Grizzly and the Pipsqueak, out the roof of tiny houses, sheds or small cabins.

Note: If using this kit on the Cubic-Mini line of stoves you’ll need to tweak the male end of our pipe to fit the stove or use our Cubic Mini adapter.  See our primer on Cubic Mini flue systems here.

Note: Since every installation is a little bit different you will need additional single wall pipe and may need additional double-wall pipe to complete your installation. Simply measure the distance from your stove’s flue flange to where the pipe will exit the roof then subtract 10″. This is the amount of single wall pipe you will need. The single wall telescoping pipe included in the kit allows for easy installation by stretching or shrinking the pipe to connect the stove to the chimney pipe.

This kit will put the roof vent approximately 16-18″ above where it exits the roof. You will need additional insulated pipe if you would like to extend higher than 18”. Insulated pipe is recommended for use outside the structure to keep flue gases hot.

Typically you want your roof vent to be above the peak of your roof line so wind gusts do not come over the top of your roof then down the vent pipe. Keeping your vent above the roof line helps prevent backdrafts. On relatively flat roofs like RV this isn’t an issue.

Code for residential installation says, “ 3 ft minimum from roof penetration and 2 ft minimum above highest point of anything within 10 ft.”
