The Story

The Navien 60/100 Vertical Roof Terminal Kit provides a complete solution for terminating a Navien boiler's flue system vertically through a roof, supplied complete with the vertical adaptor needed to transition from the boiler's horizontal spigot to a vertical run. The kit seals the roof penetration against the elements while safely venting exhaust gases clear of the building, making it the standard choice for loft conversions, flat-roof properties, or installations where a wall termination isn't practical.

Gas Safe Installation Requirement
Vertical flue terminations must be installed by a Gas Safe registered engineer and must comply with roof penetration and termination clearance requirements set out in the boiler's installation manual and current Building Regulations.
Compatibility
This kit is designed for Navien's 60/100mm concentric flue system. Confirm your boiler model's flue diameter before ordering, and check the maximum permitted vertical flue length in the installation manual, as the adaptor and terminal both consume part of that allowance.
Why This Component
Complete Roof Termination Solution
Supplied with the required vertical adaptor in the box, this kit removes the need to source a separate adaptor to transition from the boiler's horizontal outlet to a vertical run.
Weatherproof Roof Seal
The terminal is designed to seal the roof penetration against the elements, protecting the building structure while maintaining safe, unobstructed exhaust venting.
Safe Gas Venting
Directs exhaust gases, including carbon monoxide, safely up and away from occupied areas of the building — an essential safety function of any condensing boiler flue.
Matches Navien 60/100 System
Fits directly into the same 60/100mm concentric flue range used for horizontal terminations, extensions, and bends, so remaining components can be mixed and matched as the installation requires.

Frequently Asked Questions
Does this kit include everything needed for a vertical termination?
Yes — the terminal and the vertical adaptor required to transition from the boiler's horizontal spigot are both included. Additional straight extensions or bends may still be required depending on the height of the run, and are sold separately.
Will this fit a flat roof or only a pitched roof?
The kit is designed for standard pitched roof penetration. Flat roof installations typically require an additional flat roof flashing collar — check your boiler's flue installation manual for the correct accessory.
Can I install this myself?
No. Roof penetrations and flue terminations must be installed by a Gas Safe registered engineer to ensure weathertightness and gas safety compliance.
What is the maximum vertical flue length this kit supports?
Maximum vertical flue length depends on the specific boiler model — refer to the installation manual for your Navien boiler, as this terminal and its adaptor consume part of the total permitted flue length allowance.
