Start-up, calibration and operation of the burner
6.1 Notes on safety for the first start-up
6.2 Adjustments before first firing
Adjustment of the combustion head has been illustrated on
page 20.
In addition, the following adjustments must also be made:
–
Slowly open the manual valves situated upstream of the gas
train.
– Adjust the minimum gas pressure switch to the start of the
scale.
– Adjust the maximum gas pressure switch to the start of the
scale.
– Adjust the air pressure switch to the zero position of the
scale.
– Purge the air from the gas line.
Continue to purge the air (we recommend using a plastic tube
routed outside the building) until gas is smelt.
– Fit a U-type manometer or a differential pressure gauge
(Fig. 35), with the (+) fitting on the header gas pressure tap
and (-) fitting in the combustion chamber.
The manometer readings are used to calculate MAX. burner
power using the Tab. H on page 27.
– Connect two lamps or testers to the two gas line solenoid
valves to check the exact moment at which voltage is sup-
plied.
This operation is unnecessary if each of the two solenoid
valves is equipped with a pilot light that signals voltage pass-
ing through.
6.3 Burner starting
Close load controls and set switch 1)(Fig. 36) to "MAN".
Make sure that the lamps or testers connected to the solenoids,
or pilot lights on the solenoids themselves, indicate that no volt-
age is present.
If voltage is present, then immediately stop the burner and check
electrical connections.
6 Start-up, calibration and operation of the burner
WARNING
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.
CAUTION
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.
