Installation instructions
IMPORTANT
- If having to open the furnace door, let it cool
before opening it to avoid thermal shock to
the refractory lining.
- The rear factory material of the door can
show cracks after a short time of operation;
this however does not reduce its insulation
capacity nor jeopardise its lifespan.
The door is hinged and fixed according to the indicated diagram:
In these cases the two hinges on the left side are normally used
as rotating hinges (from right to left), while the two on the right
side are used as closing hinges.
The exact opposite occurs when the door must open from left
to right.
To invert rotation, just move the
door support lock nuts.
The following adjustments can be made on the door:
A
B
C
Upon commissioning, to avoid damaging
the refractory insulation, operate the burner
at minimum capacity or, if this is not possi-
ble, cause frequent stops to gradually heat
the same and obtain "cooking".

3.11 - ELECTRICAL CONNECTIONS
General warnings
Have the electrical system checked by per-
sonnel professionally qualified according to
law, attesting the adequacy:
- of the electrical system to the power loads
absorbed by the generator,
- of the earthing system,
- of the cables
- of a multi-pole switch installed outside the
boiler room, pursuant to current legislation,
easy to access so as to make any maintenance
operations quick and safe.
Adapters, multiple sockets and/or extension
cords cannot be used to power the appliance.
The electrical safety of the appliance is guaran-
teed only when it has been properly connected
to an efficient earthing system carried out as
intended by safety standards in force: pipes of the
gas, water and heating systems are absolutely
unsuitable as earthing electrodes.
ATTENTION!
THE MANUFACTURER IS NOT LIABLE FOR
INJURIES TO PERSONS AND DAMAGE
TO GOODS CAUSED BY AN INADEQUATE
EARTHING SYSTEM.
Connection to the electric power supply
The electric panels installed on the heaters pro-
vide a 400V – 50 Hz three-phase power supply,
while the auxiliary circuit is low voltage (24 V):
different voltage are prepared only on request.
Danger!
Only a qualified technician may perform the
electrical installation.
Before performing connections or any type
of operation on electrical parts, always dis-
connect electrical power and make sure that
it cannot be reconnected accidentally.
The wiring diagram and declaration of conformity are supplied
inserted in the electric panel.
