4.- INSTALLATION INSTRUCTIONS

The boiler must be installed by personnel authorised by the Department of Industry in
accordance with the applicable regulations and standards in force. However, the following
recommendations must be complied with when installing the boiler:

4.1.- Location

The boiler must be installed in a sufficiently ventilated site. It is essential to leave a space at
the top of the boiler so that it is accessible for maintenance operations. It must therefore not
be installed under a fixed worktop or any other obstacle preventing access.

4.2.- Hydraulic Installation

The hydraulic installation must be made by qualified personnel. The applicable installation
legislation is to be complied with, and the following recommendations should also be taken
into account:
- The inside of the installation piping should be thoroughly cleaned before switching on
the boiler.
- We recommend inserting cut-off valves between the installation piping and the boiler to
simplify maintenance tasks.
- The hose connected to the pressure relief valve is installed on a provisional basis.
The discharge pipes should be fitted in accordance with the current edition of the
Building Regulations.
- Before starting up the unit, it is essential to install the condensation siphon supplied with
the boiler documentation on the condensation drain tube on the back of the boiler.
- The condensation pipe should lead to a drain outlet,
as the Evolution boiler is a condensation boiler and a
large amount of water may be generated. This
connection should be made in accordance with the
regulations for draining off condensation water to
the drain network.
- Fill the siphon with water before starting up the unit,
to prevent fumes coming out of it.

4.3.- Electrical Connection

The boiler is equipped for connection at 230 V~, 50 Hz to terminals 1 and 2 of terminal strip J1
(see "Electrical Connection Diagram"). Remember to earth the appliance.
The boiler has two terminal strips, TA
room chronothermostats (see "Electrical Connection Diagram") for remote control of
heating circuits 1 and 2 respectively. To correctly connect the room thermostats, firstly
remove the bridge joining the terminals of terminal strip TA
connect the thermostat to the terminal strip.
