IMPORTANT: The weather seal (supplied) must be fitted to every flue joint to give the required level of weather protection.

The diagrams (opposite) show the components used and the maximum flue length (L) for each flue configuration.

In all cases L is measured from the outside of the boiler casing.

•To achieve the maximum flue length (L), a flue section will have to be reduced in length.

•Only the straight flue extensions can be reduced in length by cutting.

IMPORTANT: All horizontal sections must rise away from the boiler by 52mm per metre (3°) to allow the condensate to drain back to the boiler.

Calculating the flue length:

Measure the total flue length required, noting that the maximum straight flue length including the terminal is:

Horizontal 80/125mmØ: 4000mm.

Vertical 80/125mmØ / 100/150mmØ (25/32 only): 7000mm.

Then reduce the total straight flue length for each extra flue bend (excluding the vertical flue kit 90° elbow) by:

1000mm for 90°

500mm for 45°

Flue Extension lengths:

Horizontal & Vertical: 1000mm overall length.

Effective length when engaged into sockets within the flue run is 950mm.

Flue Terminal lengths:

Horizontal 80/125mmØ: 720mm

Vertical 80/125mmØ: 1080mm + cage

*Rear exit only.

**Horizontal flue runs should be kept as short as possible.
