FLUE OPTIONS
• The diagrams (opposite) show the
components used and the maximum flue
length for each configuration of 100mm and
125mm flues.
• Shaded flue components indicate the
standard 100mm horizontal flue.
• Only straight flue sections can be reduced in
length and cut.
• The flue terminal end can be fitted from the
inside or outside of the building.
• Fixing kits are supplied with the flue extension
kits.
• Horizontal 125mm and Vertical 100mm and

Then reduce the total straight flue length for
each extra flue bend (excluding the flue elbow)
by:
2000mm for 90°
1000mm for 45°
