4.5.3.2 INSTALLATION OF CONDENSATE DRAIN KIT
(see fig. 11)
The condensate drain kit must be fitted within 1
metre of the appliance flue outlet. It is
recommended that the condensate drain kit
should be fitted in the vertical plane, however it
can be fitted horizontally with care.
●
Fit the first bend to the condensate drain kit or
exhaust connection manifold by firmly pushing
in to position.
●
Using the two holes in the exhaust connection
manifold as a guide, drill a 3mm hole in each
and secure using the screws provided.
●
Connect the air inlet pipe to the air baffle as
above.
●
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).
4.5.3.3 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.
●
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 130mm hole for the passage of
the horizontal flue terminal, ensuring that there
is a 1
°
fall back to the water heater (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.
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.
●
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 (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.
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 1
°
fall towards the appliance (17mm
per 1000mm).
