4 Installation and bringing into use
In this section you can find instruction and tips for the correct placing and connection of the
boiler and the associated equipment.
Warning:
Do not place any flammable and/or gaseous substances that may cause
danger of explosion or fire in the space where the boiler is or is to be
installed.
4.1 Installation
4.1.1 Placing the boiler

Place the boiler in a moisture-free space.

Place the boiler on a strong, horizontal surface and fasten it firmly with the angle brackets and
M5 bolts supplied.

Ensure sufficient ventilation in the space where the boiler is to be installed.

As a general rule for determining the diameter of the ventilation opening you can use 2.5 times
the diameter of the flue gas outlet (at least 150 mm).

Secure the base of the boiler against slipping using an angle bracket with bolts or tack-
welding.

Make sure there is a distance between the outlet and the wall of at least 10-20 mm because of the
heat transfer from the flue gas outlet.

Ensure sufficient space around the boiler for service and maintenance work.

Provide an earthed wall socket (230 V AC) for the connection of the boiler.
4.1.2 Connection to the central heating system
PIPING
When assembling the piping the following points must be respected:

Assemble the piping in such a way that the boiler and control panel remain accessible;

Ensure sufficient ventilation in places where air can accumulate.
Note: Ensure ventilation if the piping does not slope upwards.
EXPANSION TANK
An expansion tank must always be assembled with a closed central heating system (pressure system).

Always assemble the expansion tank in the return pipe (see fig 2) as near as possible to the boiler.

The size of the expansion tank is approximately 10% of the total water capacity of the whole system.
For example; with a volume of 120 litres, assemble a 12-litre expansion tank.
