FLUE HEIGHTS & TERMINATION
The minimum flue height recommended for optimum
performance of our fireplaces is 15ft. (4.57 m) from the
top of the firebox to the top of the external flue.
The chimney must also be at least 3 feet (92 cm) higher
than the highest point where it passes through the roof
and at least 2 feet (61 cm) higher than the highest part
of the roof or structure that is within 10 feet (3.05 m) of
the chimney, measured horizontally.
It is best to position the flue so that it goes straight
up as near to the roof ridge as possible. The diagram
over page shows the minimum flue discharge heights
and positions for all wood burning and multi-fuel
applications.
In some cases, particularly when flues are towards
the bottom of a sloping roof or at the eaves, it may
be necessary to increase the flue height above these
minimum mandatory requirements. The reason for this is
to clear pressure zones created by wind hitting the roof
and nearby structures, like trees, which may interfere
with the up draught required by the fireplace.
Tall flues may need bracing, always consult your installer
for advice.
