Viessmann 60/100 1 Metre Flue Extension | 7373224

Description

The Viessmann 60/100mm 1 Metre Flue Extension is the standard length concentric straight section for extending a Vitodens flue run, whether routing horizontally to an external wall or vertically through a roof.

As the most commonly used extension length in the range, it's typically the first choice when a flue run needs to reach further than the standard 1 metre horizontal or vertical kit alone allows.

Standard 1 metre length

The most widely used extension size, ideal for reaching an external wall or roofline beyond the base flue kit.

60/100mm concentric diameter

Matches the standard Vitodens balanced flue system for direct compatibility with bends, terminals and other extensions.

Works on horizontal or vertical runs

Suitable for both horizontal wall-terminated and vertical roof-terminated flue configurations.

Combines with the 500mm extension

Pairs with the shorter 500mm section for precise total length adjustment on site.

Simple push-fit jointing

Connects using the same push-fit method as the rest of the Vitodens flue range.

Durable, weather-resistant material

Manufactured to the same specification as the wider flue range for long-term reliability outdoors.

What's the difference between this and the 1.95m extension?

This 1 metre extension can typically be cut to length on site for fine adjustment, whereas the 1.95m and 2.95m extensions are supplied as fixed, uncuttable lengths for longer runs.

Do I need a slide coupling with multiple extensions?

On longer vertical runs using several extensions, a slide coupling is recommended to accommodate thermal expansion — check the specific run length against Viessmann's flue design guidance.

Can this extension be used with the vertical flue kit as well as the horizontal kit?

Yes, 1 metre extensions of this diameter are common to both the horizontal and vertical Vitodens flue system ranges.
