When the installation and filling are completed turn on the central heating
system (section 4.4) and run it until the temperature has reached the boiler
operating temperature. The system must then be immediately flushed
through.
The flushing procedure must be in line with BS 7593:1992 code of practice for
treatment of water in domestic hot water central heating systems.
During this operation, we highly recommend the use of a central heating
flushing detergent (Fernox Superfloc or equivalent), whose function is to
dissolve any foreign matter that may be in the system.
Substances different from these could create serious problems to the
pump or other components.
The use of an inhibitor in the system such as Fernox MB-1 or equivalent is
strongly recommended to prevent corrosion (sludge) damaging the boiler and
system.
Failure to carry out this procedure may invalidate the appliance
warranty.

In order to access the inside of the boiler, it is necessary to
unscrew the fastening screws "A" of the control panel
located on the lower part of the panel itself.
The control panel moves downward and when pulled
forward rotates on two lateral hinges.
The panel stays in a semi-horizontal position, which allows
access to the inner parts of the boiler.
In order to increase the manoeuvring space, it is possible
to raise the control panel and rotate it to a fully horizontal
position.
