The Story

The Navien 60/100 500mm Flue Extension is a genuine 500mm length of 60/100mm concentric flue pipe, used to extend a flue run to the required length for safe, compliant venting. Whether reaching a more distant external wall, clearing an obstruction, or fine-tuning a vertical roof run, this extension slots directly into Navien's existing 60/100mm push-fit flue system and is compatible across the full range of Navien boilers.

Gas Safe / OFTEC Installation Requirement
Flue components must only be fitted by a Gas Safe registered engineer (gas boilers) or an OFTEC registered technician (oil boilers), as part of a compliant flue system that respects the boiler's maximum permitted flue length.
Compatibility
This extension fits Navien's 60/100mm concentric flue system, used across the current NCB gas and LCB700 Blue Flame oil boiler ranges. Confirm your boiler model uses the same 60/100mm flue diameter before ordering — larger-output models may specify an 80/125mm system instead.
Why This Component
Precise Length Extension
At exactly 500mm, this extension lets installers fine-tune a flue run to reach an external wall or roof penetration point without over- or under-shooting the required length.
Universal Navien Fit
Engineered to be compatible with all Navien boilers using the 60/100mm flue system, so it can be mixed and matched with bends, terminals, and other extensions from the same range.
UKCA & CE Certified
Carries both UKCA and CE certification, confirming compliance with current UK and European standards for flue components.
Durable, Condensate-Resistant Build
Manufactured from durable plastic (PP), matching the material used throughout the Navien 60/100 flue range for long-term resistance to acidic condensate.

Frequently Asked Questions
Will this extension fit any Navien boiler?
It is designed for Navien's 60/100mm concentric flue system, used across the current NCB gas and LCB700 oil boiler ranges. Check your specific boiler's flue diameter in its installation manual before ordering.
How many extensions can I add to a flue run?
This depends on your boiler's maximum permitted horizontal or vertical flue length, detailed in its installation manual. Every extension and bend added consumes part of that total allowance.
Is a 1000mm extension available if I need a longer run?
Yes, Navien also produce a 1000mm flue extension (GXXX002196) for the same 60/100mm system, sold separately.
Can I fit this flue component myself?
No. Flue installation and modification must be carried out by a Gas Safe registered engineer (gas boilers) or OFTEC registered technician (oil boilers) to ensure the completed system remains compliant and safe.
