11.1 FLUE OPTIONS.
The standard flue length is from 127mm to 350mm measured
from the appliance casing to the outer wall.
Extension flue kits, a vertical take-off adapter, 45° and 90° flue
bends are available to increase the length and redirect the flue as
follows.
Horizontal balanced flue:
a) From 127mm to 2500mm straight flue.
b) From 127mm to 1750mm when a 90° flue bend is
required.
c) From 127mm to 1000mm when two 90° flue bends are
required.
A 90° flue bend is equivalent to 750mm of straight flue. A 45°
flue bend is equivalent to half a 90° bend.
Refer to Figs. 21 and 22 to determine whether extension kits,
90° flue bend, 45° flue bend, or adapters are required.
The maximum number of 90° flue bends allowed is two.

hole centre line onto the wall. See Fig. 10.
Side Flue – Extend the flue hole centre line from Fig. 11 along the
appropriate wall. Check that it remains horizontal and mark a
horizontal line. Measure 222mm from the junction of the walls
and mark a vertical line which will then give the position of the
flue hole.
Drill the two fixing holes 60mm deep for No. 12 size plugs. Cut
the flue duct hole at 110mm diameter (150mm dia. for internal
fitting). Ensure that the hole is horizontal through the wall. Fit
the wall mounting bracket.
Drill the two fixing holes 60mm deep for No. 12 size plugs. For
