4.5.3.2 HORIZONTAL TERMINATION (see 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.
Depending on site conditions it may be prefer-
able to install the terminal assembly prior to fit-
ting the twin flue pipes.
Mark and drill a 130mm hole for the passage of the
horizontal flue terminal, ensuring that there is a mini-
mum 1º fall back to the boiler (17mm per 1000mm).
Insert the terminal assembly into the flue hole.
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.

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 mani-
fold 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).
Total flue length
Restrictor required
Less than 5.0 metres
50mm diameter
Less than 10.0 metres
not required
35
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
You must ensure that the entire flue system is
properly supported and connected.
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 (see 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.
