FLUE INSTALLATION
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
turret.
Subtract the length of the Standard Flue
and turret (725mm) from length L .
Subtract the full length 1m extension(s)
from the figure.
Cut one of the 1m extensions to the remainder.
Cut both tubes square taking care not to distort
the tubes.
Remove any burrs.
EXAMPLE:
Length L = 2380mm
Subtract Standard Flue+Turret — 686mm
Subtract Full Extension — 960mm
Cut Length = 734mm
NOTE: The minimum length a flue extension
can be cut to is 100mm
NOTE: Where extensions are reduced, cut
length which DOES NOT contain the seal.
ADDITION OF FLUE BENDS:
When flue bends are being used an allowance
of 98mm per bend must be allowed from the
centre line of the bend. In the example shown
using a flue extension with 2 bends will
achieve a total length of 1148mm.
