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. 37).
2. Measure the thickness of the wall from the
inside. This will be known as Wall Thickness
(Fig 38).
3. To make up the total flue length, add 145mm
(L/H Flue) or 165mm (R/H Flue) to the
Wall Thi X dimension:
Total flue length =
Wall Thi X + 145mm (L/H Flue)
Wall Thi X + 165mm (R/H Flue).
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 Thi X
is less than;
140mm
(L/H Flue) or
120mm
(R/H Flue),
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. 40).

Wall Thi X + 165mm (R/H Flue)
5. Take the
Flue Terminal Assembly
and
measure from the terminal end the dimension
below (Fig. 41). Cut the waste off the plain end.
Wall Thi X + 110mm (L/H Flue)
Wall Thi X + 130mm (R/H Flue)
6. Measure the same amount from the flange end
of the
Air Duct
and cut the waste off the plain end
(Fig. 42).

Wall Thi X + 130mm (R/H Flue)
7. The cardboard support supplied in the flue
pack should be installed onto the flue tubes of the
flue terminal assembly to ensure the flue is
supported during cutting (Fig. 43 & 44).
