NOTE: The method of connection to the electrical supply must facilitate complete electrical isolation of the appliance. Connection may be made via a fused double pole isolator with a contact separation of at least 3mm on all poles and serve the boiler and system controls only. The boiler MUST NOT be connected to the same supply as the firefront as their fuse ratings are different and subsequent damage may occur.

2.The boiler supply cable within the builders opening should be 0.75mm2 to IEC 53 code 227 (heat resistant).

3.It is preferable to route the electrical supply cable to the right hand side of the builders opening. If however it must come from the left hand side it must be routed so as not to restrict the servicing of the appliance.
