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
6.2

Adjustments prior to ignition

Combustion head adjustment is already described on page 19.
In addition, the following adjustments must also be made:
 Open manual valves up-line from the gas train.
 Adjust the minimum gas pressure switch to the start of the
scale.
 Adjust the maximum gas pressure switch to the end of the
scale.
 Adjust the air pressure switch 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. 26), with socket (+) on the gas pressure of the pipe
coupling and (-) in the combustion chamber.
The manometer readings are used to calculate MAX burner
output using the Tab. J.
 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 solenoids is
equipped with a pilot light that signals voltage passing
through.

Burner start-up

Turn off the thermostats/pressure switches and check the light
signal 2) comes on Fig. 5 on page 12.
Put the selector 1)(Fig. 27) in position "MAN".
Start of the fan motor. As the burner is not fitted with a device to
check the sequence of the phases, the motor rotation may be in-
correct.
As soon as the burner starts up, go in front of fan motor cooling
fan and check it is rotating anticlockwise or else in the direction
of the arrow shown in the diagram (burner description).
If this is not the case:
 put the switch 1) of Fig. 27 to "OFF" and wait for the control
box carries out the switching off phase;
disconnect the burner's electrical supply, since
this operation should be carried out in the ab-
sence of the electrical supply;
DANGER
 Invert the phases on the three-phase power supply;
 repeat the start-up procedure.
Start-up, calibration and operation of the burner
Before igniting the burner, see the paragraph
"Safety test - with gas feeding closed" on
page 29.
WARNING
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
Make sure that the lights or testers connected to
the solenoids, or the pilot lights on the solenoids
themselves, indicate that no voltage is present.
If voltage is present, stop the burner immediately
WARNING
and check the electrical wiring.
