INSTALLATION
10 FLUE INSTALLATION
Caution : To avoid the possibility of injury during the use
or cleaning of this appliance, care should be taken when
handling edges of sheet steel components.
The flue kits are suitable for use with the Ideal Maximiser SE
boiler only.
These kits and the associated options are suitable for both
roof and wall mounting applications.
The roof kit is suitable for both flat and pitched roof
termination, using a concentric flue (tube within tube) to run
vertically from the top of the boiler and terminating above the
roof level.
Connection to the top of the boiler is made using a
separately supplied vertical connector in both concentric and
twin pipe configurations.
Additional information covering the selection and installation
can be found with this booklet.
WEATHER PROOFING
Where the flue passes through the roof line an adequate seal
must be made. This can be achieved by using either:
●
Flat roof tile 125 or 150 mm
●
Pitched roof tile 125 mm or 150 mm
Concentric flue duct extension kits are available for flue
lengths extending beyond 1 metre. These packs contain
additional 1 metre ducts and may be cut to the desired
length.
If obstructions prevent direct flue routing then both 90° and
45° elbows can be provided to offset the flue system.
TERMINAL POSITION
Due to the high efficiency of the boiler in certain weather
conditions pluming will occur. Therefore, where possible,
terminal positions which could cause problems should be
avoided.
IMPORTANT
It is the responsibility of the installer to ensure, in practice,
that products of combustion discharging from the terminal
cannot re-enter the building or any other adjacent building
through ventilators, windows, doors, other sources of natural
air infiltration, or forced ventilation / air conditioning.
If this should occur the appliance MUST be turned OFF,
labelled as ‘unsafe’ and corrective action taken.
TERMINAL POSITION
Where the lowest part of the terminal is fitted less then 2 m
(80”) above a balcony, above ground or above a flat roof to
which people have access then the terminal MUST be
protected by a purpose designed guard. The minimum
spacing between the balcony and the terminal should be 75
mm, in order to allow a terminal guard to be fitted.
Terminal guards are available from boiler suppliers and
merchants- ask for Tower Flue Guard, Model K1. In case of
difficulty seek advice from:
Tower Flue Components Ltd.
Vale Rise, Tonbridge, Kent TN9 1TB
Telephone No. 01732 351 555
Ensure that the guard is fitted centrally.
Where the terminal is fitted within 850 mm (34”) of a plastic
or painted gutter or 450 mm (18”) of painted eaves then an
aluminium shield at least 750 mm (30”) long should be fitted
to the underside of the gutter or painted surface.
The air inlet/products outlet duct and the terminal of the
boiler MUST NOT be closer than 25 mm (1”) to combustible
material. Detailed recommendations on the protection of
combustible material are given in BS. 5440: 1990.

ASSEMBLING THE FLUE
All Concentric flue packs provided contain locking collars for ease of installation (see Frame 11).
Extension duct kits are available in 1 metre lengths. These can be cut to suit the required application.
The outer duct should be cut to the required length. However, the inner duct MUST be 20 mm greater in length to allow
connection to the remainder of the flue.
Important : Only the plain end of the ducts should be removed when cutting to length.
Note : Care should be taken to support the inner duct pipe when cutting the flue.
