Installation
5.7
Positioning the probe - electrode
Before installing the burner on the boiler, make sure the probe
and electrode are placed correctly as in Fig. 9.
5.8
Fuel supply
The burners are teamed with one-piece pneumatic proportioning
gas valves, via which the amount of gas delivered, and hence the
output produced, can be modulated.
A signal reporting pressure detected in the air circuit is carried to
the pneumatic gas valve, which delivers an amount of gas in pro-
portion to the airflow produced by the fan.
To optimise the bulk, the gas train is assembled directly on the
body of the burner.
5.8.1
Gas train assembly
The connection valve-manifold allows compensating the acci-
dental occlusion of the suction line through the distributed gas re-
duction.
WARNING
Do not turn the electrode: position it as illustrated.
Placing the electrode near the ionisation probe
may result in the control box amplifier being dam-
aged.

Explosion danger due to fuel leaks in the pres-
ence of a flammable source.
Precautions: avoid knocking, attrition, sparks and
heat.
Make sure that the fuel interception tap is closed
before performing any operation on the burner.
WARNING
The fuel supply line must be installed by qualified
personnel, in compliance with current standards
and laws.
DANGER
Disconnect the electrical supply by means of the
system's main switch.
Make sure that there are no gas leaks.
Pay attention when handling the train: danger of
crushing of limbs.
Make sure that the gas train is properly installed
by checking for any fuel leaks.
The operator must use the required equipment
during installation.
