  • Page 8 Mains connection Each Alkon 90 boiler requires a permanent mains supply of 230V 50Hz, protected by a 3 Amp fuse. The electrical supply to the boiler must be installed in accordance with current IEE (BS 7671) Regulations. A separate supply and isolating switch is required for each boiler, with at least 3 mm separation for both the phase and neutral poles.
