ROOM SEALED FLUE OPTIONS
The diagrams (opposite) show the
components used and the maximum flue
length (L) for each flue configuration.
• To achieve the maximum flue legth (L), a flue
section will have to be reduced in legth.
• Only the flue terminal or straight flue
extensions can be reduced in length by
cutting.
• The flue terminal end can be fitted from the
inside or outside of the building.
Calculating the flue length:
Measure the total flue length required, noting
that the maximum straight flue length including
the terminal is:
Then reduce the total straight flue length for
each extra flue bend by:
1000mm for each 90°
500mm for each 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 80/125mmO: 720mm
Vertical 80/125mmO: cage
Vertical 100/150mmO: cage

to outside wall.
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.
