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 maneuvering space, it is possible to raise the
control panel and rotate it to a fully horizontal position.
