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.
WARNING
Check the correct working of the adjustment, com-
mand and safety devices.

Adjustments prior to ignition

Combustion head adjustment is already described on page 17.
In addition, the following adjustments must also be made:
 open the manual valves upline of the gas train.
 Adjust the minimum gas pressure switch to the start of the
scale (Fig. 31).
 Adjust the air pressure switch to the start of the scale (Fig.
30).
 Purge the air from the gas line. We recommend using a plas-
tic tube routed outside the building and to purge air until gas
is smelt.
 Fit a U-type pressure gauge (Fig. 26) to the gas pressure
test point on the pipe coupling.
 Used to obtain the approximate burner output in the 2nd
stage using the Tab. G on page 19.
 Connect two lamps or testers parallel to the two gas line
solenoid valves VR1 and VS in order to check the exact
moment at which voltage is supplied. This operation is
unnecessary if each of the two solenoid valves is equipped
with a pilot light that signals voltage passing through.

Burner start-up

Close the remote controls and turn:
 switch 1)(Fig. 27) on "BURNER ON";
 switch 2)(Fig. 27) on "1ST STAGE".
– As soon as the burner starts make sure that the lights or test-
ers connected to the solenoids, or the pilot lights on the sole-
noids themselves, indicate that no voltage is present. If
voltage is present, stop the burner immediately and check
the electrical wiring.
As soon as the burner starts up:
– check the fan rotation direction through the
flame inspection
page 11).
WARNING
– check the fan motor rotation direction, as
shown in Fig. 28.
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.
DANGER
If voltage is present, stop the burner immediately
and check the electrical wiring.

Before igniting the burner, see the paragraph
"Safety test - with gas feeding closed" on
page 30.
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.
