Start-up, calibration and operation of the burner

5.1

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.

Adjustments prior to ignition

Combustion head adjustment has already been described in the
section "Combustion head adjustment" on page 22.
In addition, the following adjustments must also be made:
 open manual valves upstream 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.
 Adjust the pressure switch for the leak detection control
(PVP kit)(Fig. 29 on page 33) according to the instructions
supplied with the kit.
 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. 24), with socket (+) on the gas pressure of the pipe
coupling and (-)
The manometer readings are used to calculate MAX burner
output using Fig. 20 and Fig. 21 on page 25.
 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.
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
The factory setting for burners with inverter at
the ignition point is maximum rpm speed. Do
not change this parameter.
WARNING
Start-up, calibration and operation of the burner
in the combustion chamber.
Check the correct working of the adjustment, com-
mand and safety devices.
WARNING
Refer to paragraph "Safety test - with gas ball
valve closed" on page 36 before the first start-
up.
