F4 PLANNING THE INSTALLATION
All installation and maintenance work must be
carried out by competent persons4
BXW Water Requirements
The unit is designed to be connected to a cold
water rising mains supply, using 15mm table “X”
copper tube with a minimum pressure of 20 KPa
(0.2bar) and a maximum pressure of 1000 KPa
and (10 bar
).
So as to comply with the U.K. Water Bylaws a
single check valve must be fitted to the cold water
mains supplying the boiler. It is also recommended
that an isolating valve be fitted to the mains water
supply to the boiler to facilitate maintenance.
The formation of scale in hard water areas is a
problem associated with all hot water appliances.
Damage to the boiler caused by excessive scale
deposits is not covered by the manufacturer’s
warranty.
BXB jlectrical Requirements
The installation must comply with the current I.E.E
Wiring regulations, if in doubt consult a qualified
electrician.
This appliance must be earthed.
The boiler complies with the Electrical Equipment
Safety Regulations (SI1994/3260) and has been
independently tested to BS EN60335-2-63.
The boiler operates a nominal 3 kW element at
240v. 50Hz supply. A circuit diagram is provided at
the back of the manual
BXN
Installation Location
Ensure the counter top is of suitable construction
to support the working weight of the boiler. See
Fig. 1
To comply with recommendations from the health
and safety executive it is important that due
consideration be given to the safe operation of the
controls of the boiler. The boiler should therefore
be mounted in such a manner that the operator can
stand directly facing the machine with the controls
at the recommended height. See fig 2
Consideration should also be given to the servicing
requirements of the machine.
BXS Vent x Overflow Pipe Requirements
The vent and overflow pipe should be extended on
site using 15mm Speed-fit plastic tube or 15mm
Table “X” copper tube. The pipe must be laid with
a
continuous fallg
discharging to a safe and visible
position.
The vent and overflow pipe should
not be connected directly to a soil pipe and
should never be allowed to become blocked or
restricted4 See fig -
