MOUNTING THE BOILER
The fixing holes for the wall-mounting bracket should now
be drilled and plugged, an appropriate type and quantity of
fixing should be used to ensure that the bracket is mounted
securely. Once the bracket has been secured to the wall,
mount the appliance onto the bracket.
4.5.3.1 INSTALLATION OF TWIN ADAPTOR KIT (fig.
10 & 11)
•
Insert the exhaust connection manifold (A) onto the
appliance flue outlet.
•
Remove the blanking plate (located to the right of the
appliance flue outlet) and – using the same screws –
install the air inlet plate (B).
•
Using the hole in the exhaust connection manifold as a
guide, drill a 3mm hole in the appliance flue spigot and
secure the exhaust manifold connection to the flue
spigot using the screw provided (C).
•
Using the two holes in the air inlet plate as a guide, drill
a 3mm hole in each and secure the air inlet pipe/bend
using the screws provided.
The twin flue pipes extensions and accessories can now
be installed by pushing together (the plain end of each
extension or bend should be pushed approximately 50mm
into the female socket of the previous piece).

4.5.3.2 HORIZONTAL TERMINATION (fig. 12)
The twin flue system must be converted to the dedicated
concentric flue kit for termination.
•
The horizontal terminal is supplied with a built-in converter
box and cannot be shortened.
•
A 130mm hole is required for the passage of the
concentric terminal through the wall.
•
The air inlet pipe must always be level with or below, that
of the exhaust pipe.
Depending on site conditions it may be preferable to install
the terminal assembly prior to fitting the twin flue pipes.
Mark and drill a level 130mm hole for the passage of the
horizontal flue terminal. Insert the terminal assembly into
the flue hole.
Fig. 11
Push-fit the twin flue pipes onto the concentric to twin
converter box ensuring that the exhaust pipe connects to
the exhaust connection on the concentric to twin converter.
If necessary cut the plain ends (male) of the twin flue pipes
to allow connection to the concentric to twin converter.
NOTE
before cutting twin flue pipes ensure allowances have been
made for connection onto the previous piece and onto the
concentric to twin converter. The last twin Flue pipes must
be pushed 50mm onto the male spigots of the concentric
to twin converter.
NOTE
Seal the flue terminal assembly to the wall using cement
or a suitable alternative that will provide satisfactory
weatherproofing. The interior and exterior trim can now be
fitted.
4.5.3.3 VERTICAL TERMINATION (fig. 13)
The twin flue system must be converted to the dedicated
concentric flue kit for termination.
•
The vertical terminal is supplied with a built-in converter
box and cannot be shortened.
•
A 130mm hole is required for the passage of the
concentric terminal through the ceiling and/or roof.
Depending on site conditions it may be preferable to install
the terminal assembly prior to fitting the twin flue pipes.
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.
Push-fit the twin flue pipes onto the concentric to twin
converter ensuring that the exhaust pipe connects to the
exhaust connection on the concentric to twin converter.
If necessary cut the plain ends (male) of the twin flue pipes
to allow connection to the concentric to twin converter.
NOTE
•
Before cutting twin flue pipes ensure allowances have
been made for connection onto the previous piece and
onto the concentric to twin converter. The last twin flue
pipes must be pushed 50mm onto the male spigots of
the concentric to twin converter.
•
You must ensure that the entire flue system is properly
supported and connected.
•
Ensure that any horizontal sections of pipe have a 1º fall
towards the appliance (17mm per 1000mm).
