Glow-Worm Vertical Flue Terminal - 60/100

Description

The Glow-worm Vertical Flue Terminal (0020230604) is a genuine 60/100mm roof duct for vertical flue termination on Glow-worm's current condensing boiler ranges. Supplied in black with a collar, fixing bracket and cover plate, it provides a complete, weathertight roof penetration for installations where a wall termination isn't practical — typically flat conversions, loft rooms, or properties where planning or siting rules rule out a horizontal flue run.

Weather Protection

Gas Safe Installation Requirement

Vertical flue terminations must be installed by a Gas Safe registered engineer and must comply with the clearances and roof penetration requirements set out in the boiler's flue installation manual and current Building Regulations.

Adaptor Required Separately

This terminal transitions the flue to a vertical roof duct, but a separate vertical flue adaptor matched to your specific boiler range is required to connect it to the boiler's horizontal flue spigot. Confirm the correct adaptor part number for your boiler model before ordering — the Compact range, for example, uses adaptor 10031029.

Why This Component

Complete Roof Duct Assembly

Supplied with the fixing bracket, 48mm air-pipe collar and cover plate needed to complete a compliant vertical roof penetration, reducing the number of separate parts an installer needs to source.

Telescopic, Shortenable Design

The lower pipe pushes into the upper pipe as supplied, and the roof duct can be shortened under the roofline to suit different loft heights while keeping the fixing bracket secure.

Anti-Corrosive Construction

Built from durable polypropylene, the terminal resists degradation from acidic condensate over the working life of the boiler, matching the material used throughout the wider Glow-worm flue range.

Compatible Across the Current Range

Fits Glow-worm's ENERGY, ULTIMATE, and EASICOM condensing boiler families using the 60/100mm flue system, subject to fitting the correct boiler-specific adaptor.

Frequently Asked Questions

Does this terminal include everything I need for a vertical flue?

It includes the roof duct, fixing bracket, air-pipe collar and cover plate, but you will also need a boiler-specific vertical flue adaptor, sold separately, to connect the terminal to your boiler's flue spigot.

Can this terminal be shortened to fit my roof?

Yes. The vertical roof duct can be shortened under the roof to suit the installation, provided the fixing bracket remains securely mounted as described in the installation instructions.

Is this suitable for a flat roof?

This terminal is used for both flat and pitched roof installations, but a flat roof typically requires an additional flashing collar accessory — check the flue installation manual for your specific boiler range.

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.
