The water heater is ﬁ tted with an electrical supply cable for a

220-230V~50Hz mains supply.

It is to be connected to a single phase power supply with an

earth.

In order to protect the heater it is necessary to have a bipolar

switch with a minimum opening distance of 3mm.

IMPORTANT : Whenever carrying out an operation on the

electrical installation of the heater, make sure that the

heater is disconnected from the mains electrical supply

The new power cable is to have the same speciﬁ cations as the

one originally installed in the heater.

The means to isolate the power supply should be easily

accessible.

to purge the gas supply of air. Do not under any circumstances

attempt to purge the gas pipe of air by continually pressing the

On/Off button to reset. If it is necessary to do this, you must

wait at least three minutes between each press of the On/Off

button.
