5.0 Flues
5.1 Conventional Flues
The flue should be designed in
accordance with the local bye-laws
and the Clean Air Act. Draught
stabilisers are not recommended
for oil fired boilers. Sharp bends or
horizontal runs should be avoided
and the flue should terminate 2 feet
(600 mm) above the ridge of the
dwelling. Terminals which restrict
the discharge or allow ingress of
water should be avoided.
It is recommenced that when
connecting to an existing masonry
chimney a flexible stainless steel
liner of the correct diameter should
be used. The annular space must
be sealed top and bottom and filled
with insulation.
5.2 Low Level Convert/Low Level Balanced Flues Terminal Positions and Kabin Pak
Flues
Attention should be given to the position of the flue discharge; we recommend the
following guidelines be adopted.
1. The flue should not discharge beneath opening windows or within 2 metres of other
accesses to the building.
2. The flue should not discharge near internal/external corners of the building where
turbulent wind conditions could occur.
3. A terminal guard should be fitted at all times.
4. The terminal should not discharge over property boundaries.
5. Discharge into narrow passageways should be avoided.
6. The actual siting of the flue should be determined by the installer after consultation
with the householder.
7. In positioning this flue the wind direction should be considered.
Installation in exposed positions is not recommended.
