Positioning the boiler (ill. 10)
When constructing the base, ensure that after assembly
of the boiler with the burner on the front door, the door
can open without the burner hitting the wall or another
boiler. In other words, leave a space of at least 100 mm
on the door-opening side.
fig. 8
Boiler installation must be carried out by qualified
personnel only, following the manufacturer’s instruc-
tions and in compliance with all relevant laws and
regulations.
In particular, regulations regarding safety and the
construction and location of flues should be observed.
Base (ill. 9)
The GN4 boiler does not require any special kind of
foundation; a simple concrete base is sufficient, rein-
forced if necessary with metal plates to facilitate
positioning of the boiler. In some cases, for special
types of installation, a special acoustically insulated
base may be required.

Electrical connection
Completion of the electrical connection between the
control panel and boiler and the connections between
the burner and heating system will be the responsibility
of qualified installation personnel.
The boiler must be connected to an efficient earth
installation.
Ferroli S.p.A. declines all responsibility for injury to
persons and/or damage to property caused by failure to
connect the appliance to an efficient earth installation.
Water connection
Connect the boiler water circuit according to the instruc-
tions given near each coupling and in the technical
specifications.
Ensure that the pipes are not under tension. A safety
valve must be fitted in the central heating circuit as near
as possible to the boiler, ensuring there are no obstruc-
tions or gate valves between the valve and boiler.
Pressure must be 3 bars.
The appliance is not supplied with expansion tank and
installation must therefore be performed by the installer.
Remember that when cold, appliance pressure should
be between 0.5 and 1 bars.
