Safety and installation: Flue systems must be installed and commissioned by a competent person. Incorrect flue routing or termination can allow flue gases to enter the property. Always follow the installation instructions for the specific Vaillant boiler and the applicable UK regulations.
Compatibility note: This balcony flue kit is intended for use with compatible Vaillant 60/100 mm concentric air/flue systems. Boiler model, flue route, terminal position and maximum permitted flue length must be checked against the boiler’s installation manual before ordering.
Practical benefit: The variable terminal arrangement helps direct the flue discharge away from the underside of a balcony or similar obstruction, supporting a safer and tidier boiler installation.

Frequently Asked Questions
What is the Vaillant White Balcony Flue Kit used for?
It is used where a compatible Vaillant boiler requires a flue termination beneath a balcony, canopy or similar overhang. The variable terminal set helps route the flue discharge appropriately for the installation conditions.
What size flue system does this kit suit?
This kit is designed for Vaillant 60/100 mm concentric air/flue systems. Always confirm the boiler model and approved flue configuration before installation.
What is included with the kit?
The kit includes a terminal piece, straight adaptor, collar, bird guard grille, two 1 m extensions and three pipe clamps.
Can this flue kit be installed by a homeowner?
No. Flue installation and boiler commissioning must be carried out by a competent person, normally a Gas Safe registered engineer, following the boiler and flue installation instructions.
Does the flue length need to be calculated?
Yes. The maximum permitted concentric flue length depends on the boiler model and flue configuration. Additional extensions and elbows can reduce the available flue length, so the full system must be checked before installation.

Using the correct Vaillant approved flue components helps preserve the intended certified air/flue system arrangement and supports safe, reliable boiler operation when installed to the manufacturer’s requirements.
