MEASURING
THE FLUE (Extension Flue Kits):
ONLY CUT EXTENDED FLUE LENGTHS
~
As with the Standard Flue measure from the
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-
sian from the figure.
~
Cut one of the extensions to the remainder.
~
Cut both tubes square taking care not to distort
the tubes.
~
Remove any burrs.

NOTE:
Where

ADDITION
OF
FLUE
BENDS:
When
flue bends are being used
an
allowance
of
94
mm per bend must be allowed from the
centre line
of
the bend.
In
the example shown
using a
flue extension
(960
mm) with 2 bends
will achieve a total length
of
1148 mm.
