NOTE
Seal the flue terminal assembly to the wall using cement or a
suitable alternative that will provide satisfactory weatherproof-
ing. The interior and exterior trim can now be fitted.
VERTICAL TERMINATION (fig. 18)
The twin flue system must be converted to the dedicated con
-
centric 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 ver
-
tical 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 con-
nection 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 sup
-
ported and connected.
•
Ensure that any horizontal sections of pipe have a fall
of between 1 & 3º towards the appliance (1º =17mm per
1000mm).

HORIZONTAL TERMINATION (fig. 21)
The twin flue system must be converted to the dedicated con
-
centric 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 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.
INSTALLATION OF TWIN ADAPTOR KIT (fig. 19 & 20)
•
Insert the exhaust connection manifold (A) onto the appliance
flue outlet.
•
Remove the blanking plate (located to the left 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).
