FITTING THE STANDARD (2359029)
HORIZONTAL FLUE KIT (see 4.4.1)
Carefully measure the distance from the centre
of the appliance flue outlet to the face of the
outside wall (dimension X see fig. 8A). Ensure
the inner (60mm) pipe is fully inserted into the
outer (100mm) pipe (when the inner pipe is fully
inserted, it stands proud of the outer pipe by
7,5mm). Add 32mm to dimension X to give the
overall flue length (dimension Y). The standard
horizontal flue kit (part no.2359029) is suitable
for a distance (dimension Y) of up to 865mm.
NOTE
Dimension Y is measured from the end of the
terminal to the end of the outer (100mm) pipe.
The internal trim should be fitted to the flue pipe
before connection of the 90
°
bend.
If the horizontal flue kit (2359029) requires to be
cut to the correct size (dimension Y), you must
ensure that the inner (60mm) pipe stands proud
of the outer (100mm) pipe by 7,5 mm (see fig.
8B). Ensure any burrs are filed or removed and
any seals are located properly before assembly.
Hold the inner (60mm) pipe of the terminal
assembly and connect to the push-fit end of the
90
°
bend (supplied) using a twisting action. Insert
the assembled flue into the previously drilled
hole. Using the clips & screws supplied, connect
the flue assembly to the boiler, ensuring that the
terminal protrudes past the finished outside wall
by the correct length (135mm).
You must ensure that the entire flue system is
properly supported and connected.
Seal the flue assembly to the wall using cement
or a suitable alternative that provides satisfactory
weatherproofing. The exterior trim can now be
fitted.
EXTENDING THE HORIZONTAL FLUE
If the horizontal flue requires extension/s or
additional bend/s, the horizontal flue terminal kit
(2359029) must be used. Connect the bend -
supplied with the terminal kit - to the top of the
boiler using the clips, screws, & gaskets supplied.
The additionalbend & extensions have an internal
push-fit connection, care should be taken to
ensure that the correct seal is made when
assembling the flue system. Connect the required
number of flue extensions or bends (up to the
maximum equivalent flue length) to the flue
terminal using the clips, screws, & gaskets
supplied (see fig. 8 & 8A).
IMPORTANT
The flue restrictor ring must be removed or
discarded if the total flue length - including bends-
exceeds 1.0m (28e only).
NOTE
When cutting the horizontal flue terminal or an
extension to the required length, you must ensure
that the excess is cut from the plain end of the
terminal or extension, and that the inner (60mm)
pipe is 7,5mm longer than outer (100mm) pipe
(see fig. 8A & 8B). Remove any burrs, and check
that any seals are located properly.
You must ensure that the entire flue system is
properly supported and connected.
Seal the flue assembly to the wall using cement
or a suitable alternative that will provide
satisfactory weatherproofing. The interior and
exterior trim can now be fitted.
4.5.2
CONCENTRIC VERTICAL FLUE
The vertical flue terminal can be connected directly
to the appliance flue outlet.
Alternatively, an extension or bend can be
connected to the appliance flue outlet if desired
(see 4.4.2), however if additional bends are fitted,
a reduction must be made to the maximum flue
length (see table below).
