Ariston A/23 MFFI, A/27 MFFI Mounting the Appliance, Electrical Connection, Gas Connection

2.5	Mounting the Appliance	Fasten the boiler in place using the template and anchors supplied with the
		unit. It is highly recommended that a spirit level be used to position the boiler so
		that it is perfectly level.
		For additional information, please consult the instructions contained in the
		connection kit and the flue kit.
2.6	Electrical Connection	For safety purposes, have a competent person carefully check the electrical
		system in the property, as the manufacturer will not be held liable for damage
		caused by the failure to earth the appliance properly or by anomalies in the
		supply of power. Make sure that the residential electrical system is adequate for
		the maximum power absorbed by the unit, which is indicated on the rating plate.
		In addition, check that the section of cabling is appropriate for the power
		absorbed by the boiler.

The boiler operates with alternating current, as indicated in the technical data table (1.2), where the maximum absorbed power is also indicated. Make sure that the connections for the neutral and live wires correspond to the indications in the diagram. The appliance electrical connections are situated on the reverse of the control panel (see the servicing manual for further information)

Important!

2.7Gas Connection

In the event that the power supply cord must be changed, replace it with one with the same specifications. Make the connections to the terminal board located within the control panel, as follows:

-The yellow-green wire should be connected to the terminal marked with the earth symbol; make sure to re-use the ferrule mounted on the other supply cord;

-The blue wire should be connected to the terminal marked “N”;

-The brown wire should be connected to the terminal marked “L”.

Note: The diagrams for the electrical system are indicated in section 2.11.

Warning, this appliance must be earthed.

External wiring to the appliance must be carried out by a qualified technician and be in accordance with the current I.E.E. Regulations and applicable local regulations. The EuroCombi range of boilers are supplied for connection to a 230 V~ 50 Hz supply.

The supply must be fused at 3 A.

The method of connection to the electricity supply must facilitate complete electrical isolation of the appliance, by the use of a fused double pole isolator having a contact separation of at least 3 mm in all poles or alternatively, by means of a 3 A fused three pin plug and unswitched shuttered socket outlet both complying with BS 1363.

The point of connection to the electricity supply must be readily accessible and adjacent to the appliance unless the appliance is installed in a bathroom when this must be sited outside the bathroom.

The local gas region contractor connects the gas meter to the service pipe.

If the gas supply for the boiler serves other appliances ensure that an adequate supply is available both to the boiler and the other appliances when they are in use at the same time.

Pipe work must be of an adequate size. Pipes of a smaller size than the boiler inlet connection should not be used.
