Consideration must also be given to the fact that there is the
possibility of a small amount of condensate dripping from the
terminal.
• Ensure that the entire flue system is adequately supported, use
at least one bracket for each extension.
• The entire flue system must be adequately insulated to maintain
heat within the flue system thereby reducing the possibility of
condensate production.
• As the exhaust outlet pipe can reach very high temperatures it
must be protected to prevent persons touching the hot surface.
• The condensate drain pipe must be connected in accordance
with building regulations.

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.
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 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).

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.
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.
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).
