4.5.4.2 FITTING THE HORIZONTAL TERMINAL
The horizontal terminal can be installed either
from the internal or external wall. Ensure the
terminal is facing the correct way up and extends
past the finished external wall by the correct
distance (see fig. 15). Once the terminal has been
inserted through the wall the internal trim should
be fitted.
The terminal is supplied with a wall plate/external
trim that enables any drips from the terminal to
be directed away from the wall. It is not essential
to install the wall plate/external trim, however
staining to the external wall may occur as a result
of not installing this component.
The flue assembly should be sealed to the wall
using cement or a suitable alternative that will
provide satisfactory weatherproofing.
4.5.5 VERTICAL FLUE SYSTEM 80/125mm
Refer to the appliance installation instructions for
details of the distance from the centre of the
appliance flue outlet to the finished wall. Using
this dimension as a reference, mark and cut a
127mm hole in the ceiling and/or roof.
Fit the appropriate flashing plate to the roof and
insert the vertical flue terminal through the
flashing plate from the outside, ensuring that the
collar on the flue terminal fits over the flashing
(fig. 17).
IMPORTANT
The vertical flue terminal cannot be cut; therefore
it may be necessary to cut an intermediate
extension to the appropriate size to enable the
terminal to seat into the roof flashing correctly.
Assemble/connect the required components of
the flue assembly to the appliance, ensuring that
the flue pipe is secured at every 1.5-metres and
that the correct seal is made.
Ensure that any horizontal sections of the flue
system have a fall of at least 1° back to the boiler
(17mm per 1000mm)
The flue components are comprised of an 80mm
aluminium – inner – pipe, and a 125mm PVC –
outer – pipe. All flue components are “push-fit”
and can be assembled/disassembled with ease.
In addition, the flue extensions can be cut to an
appropriate length if required (see fig. 13&14).
Silicone lubricant or water can be used to ease
the assembly of the push-fit components.
Connect the vertical flue terminal to the final
extension/bend, ensuring that the terminal is
properly seated into the roof flashing and that
the correct seal is made
The flue support bracket (supplied with the
vertical flue kit) can now be fitted.
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. 4). Remove
any burrs, and check that any seals are located
properly.
You must ensure that the entire flue system is
properly supported and connected.
