Start-up, calibration and operation of the burner

6.1

Notes on safety for the first start-up

The first start-up of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.
WARNING
Check the correct working of the adjustment, com-
mand and safety devices.
WARNING

Adjustments prior to ignition

The adjustments to be carried out are:
 slowly open the manual valves situated upstream from the
gas train;
 adjust the minimum gas pressure switch (Fig. 35 on
page 29) to the start of the scale;
 adjust the maximum gas pressure switch (Fig. 34 on
page 29) to the end of the scale;
 adjust the air pressure switch (Fig. 33 on page 29) to the
start of the scale;
 purge the air from the gas line.
We recommend using a plastic tube routed outside the build-
ing and to purge air until gas is smelt.
 Fit a U-type pressure gauge or a differential pressure gauge
(Fig. 29), with socket (+) on the gas pressure of the pipe
coupling and (-) in the combustion chamber.
Used to approximately calculate the MAX burner output.
 Connect two lamps or testers to the two gas line solenoids to
check the exact moment in which voltage is supplied.
This operation is unnecessary if each of the two solenoid
valves is equipped with a pilot light that signals voltage pass-
ing through.
Before starting up the burner, it is good practice to
adjust the gas train so that ignition takes place in
conditions of maximum safety, i.e. with gas deliv-
ery at the minimum.
CAUTION
6.2.1

Rpm sensor

This is located inside the motor cover and measures the rpm us-
ing the reading plate.
The rpm sensor is factory set.
To ensure that the burner operates correctly, the
rpm sensor must be positioned as shown in
Fig. 30.
WARNING
If it needs adjusting, see the section "Positioning
the rpm sensor" on page 32.
