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.

Operations before start-up

Ensure that the gas supply company has carried out the supply line vent operations, eliminating air or inert gases from the piping.

Slowly open the manual valves situated upstream the gas train.

Adjust the minimum gas pressure switch (Fig. 22) to the start of the scale.

Adjust the maximum gas pressure switch (Fig. 23) to the end of the scale.

Adjust the air pressure switch (Fig. 24) to the start of the scale.

Check the gas supply pressure by connecting a

pressure gauge to the pressure test point 1)(Fig. 25)
of the minimum gas pressure switch: it must be low-
er than the maximum allowed pressure of the gas
train, as shown on the characteristics label.
An excessive gas pressure can
damage the components of the
gas train and lead to a risk of
explosion.
DANGER
Bleed the air from the piping of the gas train, con-

necting a plastic tube to the pressure test point
1)(Fig. 25) of the minimum gas pressure switch.
Take the vent tube outside the building so you can
notice the smell of gas.
Connect two lamps or testers to the two gas line so-

lenoids to check the exact moment at which voltage
is supplied.
This operation is unnecessary if each of the two so-
lenoids is equipped with an indicator light that sig-
nals voltage passing through.
Before starting up the burner, it is
good practice to adjust the gas train
so that ignition takes place in condi-
tions of maximum safety, i.e. with gas
