4.5.3.2 HORIZONTAL TERMINATION (fig. 14)
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.
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 con-
centric 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 ex-
terior trim can now be fitted.
4.5.3.3 VERTICAL TERMINATION (fig. 15)
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 con-
centric 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 previ-
ous piece and onto the concentric to twin con-
verter. 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).

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. 12 & 13)
•
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).
