The Story

The Navien 60/100 90 Degree Flue Bend is a genuine Navien flue elbow that introduces a full right-angle directional change into a 60/100mm concentric flue run. It is the component installers reach for when a flue needs to turn a corner entirely — transitioning from a horizontal boiler spigot to a vertical rise, or routing around a beam or joist that a 45° bend can't clear. It is UKCA and CE certified and suitable across Navien's current gas and oil boiler ranges.

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. Each bend reduces the maximum permitted straight flue run — consult the boiler's installation manual to confirm the total permitted flue length after adding this component.
Compatibility
This bend 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
Full Right-Angle Routing
A 90° bend gives the sharpest available turn in the Navien flue range, useful for transitioning cleanly between a horizontal and vertical run in a single fitting rather than stacking two 45° bends.
Universal Navien Compatibility
Designed to be compatible with all Navien boilers using the 60/100mm flue system, spanning the current NCB gas and LCB700 oil ranges.
UKCA & CE Certified
Carries both UKCA and CE certification, confirming compliance with current UK and European standards and regulations for flue components.
Durable PP Construction
Manufactured from durable plastic (PP), matching the material used throughout the Navien 60/100 flue range for consistent long-term weather and condensate resistance.

Frequently Asked Questions
Will this bend 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.
Does adding this bend reduce my maximum flue length?
Yes. Every elbow in a flue run reduces the total permitted straight-pipe length. Refer to your boiler's installation manual for the length deduction per bend.
What's the difference between this and the 45° bend?
The 90° bend gives a full right-angle turn in a single fitting, while a 45° bend offers a gentler directional change — useful for smaller offsets around obstacles rather than a full horizontal-to-vertical transition.
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.
