ELECTRICAL CONNECTION
Warning: This boiler must be earthed.
All system components must be of an approved type.
Connection of the whole electrical system and any heating system controls to the electrical supply must be
through a common isolator.
Isolation should preferably be by a double pole switched fuse spur box having a minimum contact separation
of 3 mm on each pole. The fused spur box should be readily accessible and preferably adjacent to the boiler.
It should be identified as to its use.
A fused three pin plug and shuttered socket outlet may be used instead of the fused spur box, provided that:
a) They are not used in a room containing a bath or shower.

The mains electrical supply must be maintained at all times in order to provide domestic hot water and frost
protection.
It is recommended that a room thermostat is fitted.
Thermostatic radiator valves may be installed in addition to the room thermostat.
