Flue terminals should be fitted on all flues, the
terminal must be of the approved type, and
have outlet grilles on all sides giving a total
free area of at least double that of the flue.
Caution
It is imperative that the flue should be properly
sealed where it passes through the roof, this
can best be achieved by using the approved
method of roof flashing plate and cravat.
Note
It should be noted that claims made under
warranty and attributed to the ingress of water
may not be considered especially if an
approved method of sealing has not been
used, or if the design of the flue has not made
provision for possible condensation problems.
5.0 Electrical supply
Wiring external to the unit heater must be
installed in accordance with any Local,
National, and European regulations, as well
as meeting the appropriate requirements of
IEE regulations.
The means of connection to the main
electrical supply must allow for complete
electrical isolation of the heater, the supply
should only be used to serve the heater itself
and no other plant or equipment. The position
of the isolation switch must be such that it is
adjacent to the heater and easily accessible at
all times. In addition, the isolator itself must
have a contact separation of not less than
3mm. (as per BS5991 clause 20.2).
All connections must be checked to ensure
that they are secure, and free from corrosion.
Terminals and connections should also be
checked to ensure that no stray strands are
bridging terminals.
Electrical continuity should also be checked
Cables, conduit, and fittings that are used to
make the connection between the isolator and
the heater must conform to the appropriate
IEE regulations.
All heaters are supplied fused and pre-wired,
all must be earthed.
The Control fuse ratings are detailed on the
appliance data plate.
Warning
Ensure that the electric and oil supplies are
turned off before any electrical work is carried
out on the heater. Ensure that wiring cannot
make contact with any surfaces liable to be
subject to high temperatures or where the
insulation of the wiring could be impaired as a
result of such contact
.
Final connections for any additional external
controls must be completed on site, and must
be carried out according to IEE regulations.
Separate user information is provided for the
time control unit and the burner, and forms
part of the product information pack which
accompanies every heater when despatched.
Caution
The main electrical supply must not be
switched off or disconnected as a method for
stopping the heater ,the exception to this is in
an emergency,
or during servicing when the controls must be
completed on site and the heat exchanger has
been allowed to cool sufficiently to prevent
any damage from occurring , Claims will not
be considered if they have resulted from
incorrect wiring or the incorrect use of the
heater
Always ensure that the appropriate
personal protective equipment is used.
