2.5. MOUNTING THE APPLIANCE
2.6. ELECTRICAL CONNECTION
For safety purposes, have a competent person carefully check the
electrical system in the property, as the manufacturer will not be held
liable for damage caused by the failure to earth the appliance
properly or by anomalies in the supply of power. Make sure that the
residential electrical system is adequate for the maximum power
absorbed by the unit, which is indicated on the rating plate. In
addition, check that the section of cabling is appropriate for the
power absorbed by the boiler.
The boiler operates with alternating current, as indicated in the
technical data table (1.2), where the maximum absorbed power is
also indicated. Make sure that the connections for the neutral and live
wires correspond to the indications in the diagram. The appliance
electrical connections are situated on the reverse of the control panel
(see the servicing manual for further information)

2.7. GAS CONNECTION
The local gas region contractor connects the gas meter to the
service pipe.
If the gas supply for the boiler serves other appliances ensure that an
adequate supply is available both to the boiler and the other
appliances when they are in use at the same time.
Pipe work must be of an adequate size. Pipes of a smaller size than
the boiler inlet connection should not be used.

supplied for connection to a 230 V
~
50 Hz supply.
The supply must be fused at 3 A.
The method of connection to the electricity supply must facilitate
complete electrical isolation of the appliance, by the use of a fused
double pole isolator having a contact separation of at least 3 mm in
all poles or alternatively, by means of a 3 A fused three pin plug and
unswitched shuttered socket outlet both complying with BS 1363.
The point of connection to the Electricity supply must be readily
accessible and adjacent to the appliance unless the appliance is
installed in a bathroom when this must be sited outside the
