MAINTENANCE
To keep the boiler in efficient and safe operating condition, we
recommend that the following checks are performed at least once
a year (according to reference standards):
• Check all seals on the gas components and replace gaskets
to restore perfect seal as required.
• Check all seals on the water components and replace
gaskets to restore perfect seal as required.
• Visually check combustion and the combustion chamber;
dismantle and clean the burner if necessary.
• Check the primary exchanger and clean it if necessary
• Check functioning of the gas safety systems: the insufficient
gas safety device (ionisation electrode for electronic ignition
boilers);
• Check functioning of the heating safety systems: the safety
thermostat for temperature limit, the safety for pressure limit:
• Check the flue exhaust safety device.
• Check the max. and min. gas pressure and the modulation.
• Check that the electrical connection conforms to the
description in the instruction manual for the boiler.
When dismantling the boilers casing, be careful when removing
the side panels after having removed the front panel; the side
panels are removed by undoing the lower and front fixing screws
and then removing as shown in fig.1, lifting and then pulling away.
The new side panels on the Midy series are connected to the
boiler frame by means of two hooks which correspond with
two slots on the frame to ensure quick and efficient fixing.

B. Turn the boiler 180° supporting it by hand.
C. Lift the box. and remove the packing pieces. Lift the

incorrect handling of the boiler.

The packing materials (cardboard) are recyclable.
