5.9 Side Flue Preparation
1. For both Left and Right Hand Flue - Measure
the distance from the wall to the nearest line
marked from the template. This will be known as
dimension X (Fig. 45).
2. Measure the thickness of the wall from the
inside. This will be known as Wall Thickness
(Fig 46).
3. To make up the total flue length, add 90mm
(30,
40, 50 models) or 145mm (60, 70, 80 models) to the
Wall Thickness + X dimension (Fig. 47):
Total flue length =
Wall Thickness + X +
90mm (30, 40, 50)
Wall Thickness + X + 145mm (60, 70, 80).
NOTE: if total calculated flue length exceeds
500mm (19
5
/
8
in), a flue extension kit will be
required.
CUTTING THE FLUE
NOTE: If Wall Thickness + X is less than;
195mm (30, 40, 50 models) or
140mm (60, 70, 80 models),
it will be necessary to cut the components of
the flue to make up the appropriate size.
4. Take the Flue Duct and measure the
dimension below from the flared end. Cut the
waste off the plain end (Fig. 48).
Wall Thickness + X + 90mm (30, 40, 50 models)
Wall Thickness + X + 145mm (60, 70, 80 models)
5. Take the Flue Terminal Assembly and
measure from the terminal end the dimension
below (Fig. 49). Cut the waste off the plain end.
Wall Thickness + X + 50mm (30, 40, 50 models)
Wall Thickness + X + 105mm (60, 70, 80 models)
6. Measure the same amount from the flange end
of the Air Duct and cut the waste off the plain end
(Fig. 50).
Wall Thickness +X + 50mm (30, 40, 50 models)
Wall Thickness + X + 105mm (60, 70, 80) models
7. The cardboard support supplied in the flue pack
should be installed onto the flue tubes to ensure
the assembly is supported during cutting
(Fig. 51 & 52).
