The Glow-worm Compact Vertical Flue Adaptor (10031029) is the boiler-specific component required to connect a Glow-worm Compact combi boiler to a vertical roof duct. It transitions the boiler's horizontal flue spigot into a vertical 60/100mm run, and is the correct adaptor to pair with the Glow-worm Vertical Flue Terminal (0020230604) on Compact range installations.
Vertical
Adaptor Function
Gas Safe Installation Requirement
Flue components must only be fitted by a Gas Safe registered engineer as part of a compliant, boiler-manufacturer-approved flue system.
Compact Range Only
This adaptor is specific to the Glow-worm Compact combi boiler range. Other Glow-worm ranges (ENERGY, ULTIMATE, EASICOM) use a different vertical flue adaptor part number — check compatibility against your exact boiler model before ordering.
Why This Component
Boiler-Specific Fit
Engineered specifically for the Compact boiler's flue spigot geometry, ensuring a correct, manufacturer-approved seal between the boiler and the vertical roof duct.
Enables Vertical Termination
Without this adaptor, a Compact boiler's flue cannot be transitioned to a vertical roof penetration — it's the single component that makes a roof termination possible on this range.
Push-Fit Installation
Uses the same tool-free push-fit jointing as the rest of the Glow-worm 60/100mm flue system, keeping installation quick and consistent.
Matches the Wider Flue Range
Once fitted, the adaptor connects directly to the Glow-worm Vertical Flue Terminal (0020230604) and any further extensions or bends from the same 60/100mm system.

Frequently Asked Questions
Will this adaptor fit any Glow-worm boiler?
No. This adaptor is specific to the Compact combi boiler range. Other Glow-worm ranges use a different vertical flue adaptor part number — check your boiler's installation manual before ordering.
Do I need anything else to complete a vertical flue installation?
Yes — this adaptor connects the boiler to a vertical roof duct, such as the Glow-worm Vertical Flue Terminal (0020230604), which is sold separately along with any required extensions.
Can I install this myself?
No. Flue components must be installed by a Gas Safe registered engineer to ensure the completed system is safe and compliant.
Does this adaptor work with horizontal flue installations too?
No, this is a vertical flue adaptor specifically for transitioning to a roof termination. Horizontal installations use a separate standard horizontal flue kit.
