RV/Bus Roof Exit Flue Kit

RV/Bus Roof Exit Flue Kit

from 345.00

A roof installation is one of the easiest and cheapest installations for wood stoves. This kit comes with everything you need to safely get through the roof of your RV, Bus, or other similar structures like shepherd huts – with relatively flat roofs.

Note: This kit does not fit seamlessly with the Cubic Cub or Cubic Grizzly Mini Stoves. For Cubic components check out the Cubic Double Wall Flue Pipe or our Flat Roof Exit Kit.

Flue Kits are on backorder until April 2019.

4" Flue Exit

5" Flue Exit

This kit is for venting 5” stoves (like our Dwarf 5kw Small Wood Stove) out the roof of tiny houses, sheds or small cabins.

Included in this kit:

  • 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)


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.”
