4.5.3.3 HORIZONTAL TERMINATION (fig. 11)
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 130 mm hole is required for the passage of
the concentric terminal through the wall.
Depending on site conditions it may be preferable
to install the terminal assembly prior to fitting the
twin flue pipes.
Mark and drill a 130 mm hole for the passage of
the horizontal flue terminal, ensuring that there is
a 1º fall back to the boiler (17 mm per 1000 mm).
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 sockets of the concentric to twin
converter.
NOTE
You must ensure that the entire flue system is
properly supported and connected.
When cutting an extension to the required length,
you should ensure that the excess is cut from
the plain end of the extension. Remove any burrs,
and check that both seals are located properly.
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.
4.5.3.4 VERTICAL TERMINATION (fig. 12)
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 130 mm 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 50 mm 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 (17 mm
per 1000 mm).
•
The convertor box on the vertical terminal will
have to be temporarily removed when inserting
the terminal through the flashing.
•
The condensate trap must be primed with water
prior to commissioning the boiler.

CONNECTING THE GAS AND WATER
The appliance is supplied with an accessories
pack that contains large and small sealing wash-
ers, service valves, and pipe connections.
The service valves are of the compression type,
the pipe connections have plain copper ends.
When connecting pipework to the valves or con-
nections, tighten the compression end first, then
insert the sealing washers before tightening the
valve or connection to the appliance. It will be
necessary to hold the valve or connection with
one spanner whilst tightening with another.
4.6.1
GAS (fig. 6)
The appliance is supplied with a 15 mm service
valve, connect a 15 mm pipe to the inlet of the
valve, and tighten both nuts.
NOTE
It will be necessary to calculate the diameter of
the gas pipe to ensure the appliance has an
adequate supply of gas.
