Using the clamp, gasket and screws supplied, se-
cure the flue bend to the appliance flue spigot.
The 60mm M & F adaptor (supplied with the flue
kit) should be discarded.
NOTE
Fit the internal trim to the flue assembly prior to
connecting the flue pipe to the bend.
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 exterior trim can now be fitted.
4.5.1.1 EXTENDING THE FLUE
Connect the bend - supplied with the terminal kit -
to the top of the boiler using clamp (supplied) see
fig. 7. The additional bends & extensions have
push-fit connections, care should be taken to
ensure that the correct seal is made when assem-
bling the flue system. Connect the required number
of flue extensions or bends (up to the maximum
equivalent flue length) to the flue terminal (see fig.
7 & 8).
The flue system should have a 1º rise from the
boiler to outside, to ensure any condense fluid that
forms, is allowed to drain back to the appliance.
NOTE
When cutting an extension to the required length,
you must ensure that the excess is cut from the
plain end of the extension (see fig. 7 & 8). Remove
any burrs, and check that all seals are located
properly.
You must ensure that the entire flue system is
properly supported and connected.
eal the flue assembly to the wall using cement or
a suitable alternative that will provide satisfac-
tory weatherproofing. The interior and exterior trim
can now be fitted.
4.5.2
CONCENTRIC VERTICAL FLUE
The appliance can be used with either the Vokera
condensing 60/100mm concentric flue system or
the optional 80/125mm concentric flue system.
NOTE
These instructions relate
only
to the Vokera
condensing 60/100mm concentric flue system.
For specific details on the installation of the 80/
125mm concentric flue system please refer to the
instructions supplied.
The vertical flue terminal can be connected di-
rectly to the appliance flue outlet. Alternatively, an
extension or bend can be connected to the appli-
ance 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).
