Notes: -
The method of connection to the electrical supply must facilitate complete isolation and should preferably be via
a fused double pole isolator having a constant separation of at least 3mm in all poles and supplying the
appliance ONLY.
Alternatively connections may be made via a 3 pin plug and unswitched socket; both complying with the
requirements of National or Local Regulations.
Neither thermostat nor switches are supplied as standard equipment. When thermostats are included to control
the temperature of the heated zone in question, they should be incorporated into the electrical circuit as shown
in the diagrams above and be positioned such that their temperature sensor has an unrestricted ‘view’ of the
appliance burner tiles.
Important: In the event of an electrical fault after installation of the appliance, preliminary system checks are
required to be carried out, i.e. earth continuity, polarity and resistance to earth.
