Door opening reversal procedure
Should it be necessary to reverse the door opening direction, proceed as follows:
1. Exchange the external nut (or bush) of a hinge with the diametrically opposite closing bush. Then secure the cone on the hinge
side to
the door with the internal nut.
2. Repeat the operation for the other hinge.
3. Use the appropriate nuts of the hinges to make any adjustments.

Burner connection
It must be remembered that the electrical board of the boiler supports a two-stage burner.
Before installing, it is advisable to thoroughly clean the inside of all fuel supply pipes in order to remove any residues which may
compromise the proper functioning of the boiler.
Check the maximum pressure value in the furnace indicated in the technical data tables. The value measured can increase by 20% if
the fuel used is naphta rather than gas or diesel-oil. In addition, perform the following checks:
a) Check internal and external sealing of the fuel supply system.
b) Regulate the fuel supply rate according to the capacity required by the boiler.
c) Check that the boiler is supplied with the type of fuel for which it is pre-adjusted.
d) Check that the fuel supply pressure is within the values indicated on the burner plate.
e) Check that the fuel supply system is sized for the maximum capacity needed by the boiler and is equipped with all the safety and
regulating devices required by the regulations mentioned above.
f ) Ensure that the ventilation of the area is sufficient to guarantee air flow as required by law and so as to achieve perfect
combustion.
In particular, when using gas it is necessary to:
g) Check that the supply line and gas train comply with the relevant regulations in force.
h) Ensure that all gas connections are sealed.
i) Ensure that the gas pipes are not used to earth electrical devices
If the boiler is not used for a certain period, cut off the fuel supply
