8.6 Fitting The Flue
HORIZONTAL FLUE
1. The standard flue is suitable for lengths 200mm
minimum to 965mm maximum (measured from the
edge of the flue elbow outlet).
Rear Flue: maximum wall thickness - 865mm
Side Flue: maximum wall thickness - 805mm
(left or right)
2. If using the optional internal fitting kit, flue extension kit
or elbows, refer to the instructions provided with the
kits.
3. Fit the captive nuts supplied in the kit to the boiler outlet
(Fig. 21) to match the slots on the flue elbow for rear,
side and 45º flue exit.
4. For rear exit - measure the wall thickness (Fig. 22 &
23) and to this dimension add 100mm. This dimension
to be known as (X).
i.e. (X) = wall thickness + 100
5. Take the air duct and mark off (X) from the terminal end
as indicated in the diagram (Fig. 24) and cut to size.
6. Take the flue duct and add 75mm to the dimension (X)
(Fig. 24) and cut to size.
7. For side exit - measure the distance from the edge of
the backplate to the inner face of the wall (Fig. 22) and
to this dimension add the wall thickness + 150mm. This
dimension to be known as (Z).
i.e. (Z) = backplate to wall + wall thickness + 150
8. Take the air duct and mark off (Z) from the terminal end
as indicated in the diagram (Fig. 24) and cut to size.
9. Take the flue duct and add 75mm to the dimension (Z)
(Fig. 24) and cut to size.
IMPORTANT: Check all measurements before cutting.
