Gas/electrical connections

Gas connection

The gas distribution system must be
connected to the gas train by a
technician.
The diameter of the piping must be
calculated so that load loss does not
exceed 5% of distribution pressure.
The external filter should be installed on
the valve with a clean connection piece,
in the horizontal position, with the cover
in the vertical position to ensure
maintenance access.
No other setup is authorised.
The quarter-turn hand-operated valve
(not supplied) should be assembled
upstream and as close as possible to the
external filter or to the valve (bag filter).
The threaded fittings used must comply
with current standards (tapered external
thread, parallel internal thread) and all
threads rendered leak-proof.
Allow enough space for access to set
the gas pressure switch.
Pipes must be drained upstream of the
quarter-turn hand-operated valve.
Connections performed in situ must be
tested for leaks using foam designed for
this purpose.
No leakage should be detected.

Electrical connection

The electrical setup and connections
must be performed in accordance with
the standards in force.
The earth wire must be connected
and tested.
See the diagram of electrics for
connecting the burner and its regulation.
The burner is delivered to be operated
with a 400 V- 50 Hz three-phase power
supply with neutral conductor and earth.
The blower motor is a direct start-up
motor.
A frequency variator can be installed as
an option.
Running on three phase
230 V - 50 Hz requires: the motor
couplings and switch thermal relays to
be replaced and a 630 VA isolating
transformer to be used on the control
circuit (not supplied).
For other voltages and frequencies,
please contact us.

Electrical connections
1) burner
- Integrated electric control cabinet.
• Use cable glands to guarantee the
degree of protection.
All the power and control connections
are connected to the control cabinet
terminal.
Ensure that you have sufficient cable
length to guarantee the rotation of the
burner body following setup.
• Check and adjust the rating of the
protection devices, the thermal relays
and the diameter of the wiring
according to the specifications of the
motor and the voltage available.
Wiring is not supplied.
- Separate electric control cabinet.
The control cabinet should be setup:
- either against a wall,
- or on a frame anchored to the
ground.
All the power and control connections
are connected between the control
cabinet and the connection box terminal
block on the burner body.
The other installation conditions are
identical to those for the integrated
control cabinet.
2) gas train
• Connect the standby points to the
valve:
- on the control cabinet,
- or on the connection box on the
burner body.
