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. Best practice in stove configuration is all female joints facing up so that any moisture or creosote stays inside the pipe/stove and not leaking out joints. The Cubic uses a male fitting on the stove so our pipe needs to be crimped a bit more or ground down to fit correctly inside the flue flange.

The Roof Exit Kit comes with the following parts:

  • Roof Support Bracket (Secures & supports pipe at the roof line)
  • 20” Double Wall Insulated Stainless Steel Pipe (2″ Clearance from combustibles)
  • Storm Collar (Fits around insulated pipe and keeps elements of the pipe boot joint)
  • Silicone High Temp Pipe Boot 11″ Round Base (Seals pipe to roof line)
  • Roof Vent / Cap (Covers the top of the insulated pipe)
  • Single to Double Adapter (Connects insulated pipe to single wall stove pipe)
  • Adjustable Interior Trim Plate (Trims out interior and works on flat & pitched roofs)
  • Single Wall Telescoping (Allows some margin to easily install single wall pipe between the chimney pipe and stove flange)
  • Insulated Pipe Clamps x 2 (Secures roof vent and single to double adapter to the insulated pipe)
  • Single Wall Pipe Clamps x 1 (Secures telescoping pipe to adapter)


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.”


*Note: If you planning on using this kit with a Cubic-Mini checkout this video on how to get our pipe to work with the male flue flange, or you can use our Cubic Mini adapter.
