outside wall to the centre line of the flue tur ­
ret (length L).
► Subtract the usable length of the standard
flue (634 mm) from length L.
► Subtract the usable length of the turret
(52 mm) from length L.
► Subtract 960 mm for each full length exten ­
sion from the figure.

using a flue extension (960 mm) with 2 bends
will achieve a total length of 1148 mm.
