Installing the flue system
Care should be exercised when determining
the position of the appliance and route of the
flue system with respect to hidden obstruc-
tions such as pipes, cables, etc.
5.5
Fitting the flue
The top flue outlet permits both horizontal and
vertical flue applications to be considered,
alternatively, the Vokera twin flue system can
be utilised if longer flue runs are required.
5.5.1
Concentric horizontal flue
(For concentric vertical flue, see 5.5.2)
(For twin flue applications, see 5.5.3)
The appliance flue outlet elbow can be rotated
at 90º intervals on its vertical axis allowing the
flue system to exit the appliance casing at the
rear, to the left, & to the right. In addition the
flue may be extended from the outlet elbow in
the horizontal plane (see 3.4.4), however if the
flue is to be extended and/or additional bends
are to be fitted, a reduction must be made to
the maximum flue length (see table below).
Horizontal flue terminal and accessoires
Using the fig. 13 as a reference, mark and drill
a 115mm hole for the passage of the flue pipe.
The hole should have a 1º drop from the boiler
to outside, to eliminate the possibility of rain-
water entering the appliance via the flue.
5.5.1.1 Standard horizontal flue (See 5.5.1.2 for
extending the horizontal flue)
The flue terminal (part no. 0225700) is suitable

Discard the bend & inner (small) flue clip
supplied with the flue terminal.
Carefully measure the distance from the cen-
tre of the appliance flue outlet to the face of the
outside wall (dimension X) and add 34mm to
give you dimension Y (see fig. 15).
Measure from the terminal end of the concen-
tric flue pipe and mark off dimension Y. Cut
only the outer flue pipe at this mark.
Mark dimension Y on the inner flue pipe then
add 10mm and cut at the new mark.
This results in the inner flue pipe being 10mm
longer than the outer flue pipe.
Insert the flue pipe into the previously drilled
flue hole.
Pull it towards the appliance flue bend and
insert the inner flue pipe into the push-fit socket
of the bend until the outer flue pipe butts
against the edge of the appliance flue bend.
Take the outer flue clip, seal, & screws (sup-
plied with the flue terminal kit) and secure the
flue pipe to the appliance flue bend.
You must ensure that the entire flue system is
properly connected.
Check that the terminal protrudes past the
finished wall by the correct length (115mm).
Seal the flue assembly to the wall using ce-
ment or a suitable alternative that will provide
satisfactory weatherproofing. The exterior
trim can now be fitted.
5.5.1.2
Extended horizontal flue
(see fig. 15a)
Discard the bend & inner (small) flue clip
supplied with the flue terminal.
Insert the flue terminal into the previously
drilled flue hole.
Connect the required bends and/or extensions
to the flue terminal working back towards the
boiler whilst maintaining a 1°fall (17mm per
1000mm) away from the boiler.
All bends and extensions are push-fit and
require no clips or screws, however care should
be taken to ensure that the correct seal is
made when assembling the flue system.
