Navien 60/100 45 Degree Flue Bend

Description

The Navien 60/100 45 Degree Flue Bend is a genuine Navien flue elbow that introduces a 45° directional change into a 60/100mm concentric flue run. Built to fit the same push-fit system used across the Navien NCB gas combi and system boiler range, it lets installers route the flue around structural obstacles, offset a termination point, or transition between horizontal and angled sections without introducing a full 90° turn.

Gas Safe Installation Requirement

Flue components must only be fitted by a Gas Safe registered engineer 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 is designed for Navien's 60/100mm concentric flue system, used across the current NCB gas combi and system boiler range. Confirm your boiler model uses the same 60/100mm flue diameter before ordering — larger-output Navien models may specify an 80/125mm system instead.

Why This Component

Precise 45° Routing

A 45° angle offers a gentler directional change than a 90° elbow, useful for gradually offsetting a flue run around joists, beams, or other obstacles while minimising flow resistance.

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.

Push-Fit Compatibility

Designed to integrate seamlessly with the wider Navien 60/100 flue accessory range, including straight extensions, 90° bends, and terminal kits.

Compact and Lightweight

At just 0.23kg and 150 x 100 x 100mm, the bend is easy to handle and fit in tight roof voids or service cupboards.

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 boiler range. Check your specific boiler's flue diameter in its installation manual before ordering, as larger-output models may use an 80/125mm system.

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.

Can I fit this flue component myself?

No. Flue installation and modification must be carried out by a Gas Safe registered engineer to ensure the completed system remains compliant and safe.

Is this bend suitable for both horizontal and vertical flue runs?

Yes, a 45° bend can be used to redirect the flue in either horizontal or vertical sections of the system, subject to the boiler manufacturer's routing rules.
