2.4CLEARANCES

In order to allow for access to the interior of the boiler for maintenance purposes, the boiler must be installed in compliance with the minimum clearances indicated in FIG. 2.2

2.5MOUNTING 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.

2.7ELECTRICAL 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 information table section in 6, 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!

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 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
