The Story

The Navien 60/100 1000mm Standard Horizontal Flue Kit is the standard through-wall termination kit supplied with, and compatible across, the Navien NCB gas condensing boiler range. Manufactured from high-quality polypropylene (PP), it resists the corrosive effect of acidic flue condensate far better than untreated aluminium, protecting both the flue and the boiler from long-term degradation.

Kit
Gas Safe Installation Requirement
Flue installation must be carried out by a Gas Safe registered engineer, with the terminal positioned in accordance with the clearances set out in the boiler's installation manual and current Building Regulations.
Compatibility
This kit is sized for Navien's 60/100mm concentric flue system and is the kit supplied as standard with the Navien NCB300-28K combi boiler. Confirm your boiler's flue diameter before ordering, as larger-output Navien models may require an 80/125mm system.
Why This Component
Corrosion-Resistant PP Construction
Polypropylene prevents the corrosion that can affect aluminium flue components over time, keeping condensate contained and pollution out of the boiler's flue passages.
Standard 1000mm Length
Provides a straightforward 1000mm through-wall run, suitable for most standard wall thicknesses without needing additional extensions.
Compatible Across the NCB Range
Uses the same 60/100mm push-fit system as the wider Navien flue accessory range, including bends, extensions, and vertical terminal kits.
Simple, Tool-Free Installation
Push-fit jointing keeps installation quick and consistent, reducing the risk of an incomplete or leaking joint at commissioning.

Frequently Asked Questions
Is this the same kit supplied with the NCB300-28K boiler bundle?
Yes, this is the identical GXXX002208 1000mm Standard Horizontal Flue Kit supplied as standard with the Navien NCB300-28K combi boiler bundle, sold here separately for replacement or spare purposes.
What is the maximum total horizontal flue length I can achieve?
The Navien NCB300 range permits up to 8m of horizontal 60/100mm coaxial flue in total, including this kit — additional extensions and bends are available separately, each reducing the remaining allowance.
Will this fit boilers other than the NCB300?
It is sized for Navien's 60/100mm flue system, used across the current NCB gas boiler range. Confirm your specific boiler's flue diameter in its installation manual before ordering.
Can I shorten this flue kit to fit a thinner wall?
Navien horizontal flue kits are designed to be cut to length on site by the installing engineer in accordance with the manufacturer's installation instructions.
