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.
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)

In the event that the power supply cable 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".

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. This
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. It should not be less than 22mm to within 1
metre of the boiler.
