Start-up, calibration and operation of the burner
6.1 Notes on safety for the first start-up
6.2 Adjustments prior to ignition
The adjustments to be carried out are:
➤
Slowly open the manual valves situated upstream from the
gas train.
➤
Adjust the minimum gas pressure switch (Fig. 30) to the start
of the scale.
➤ Adjust the maximum gas pressure switch (Fig. 29) to the end
of the scale.
➤ Adjust the air pressure switch (Fig. 28) 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.
Used to approximately calculate the MAX burner output.
➤ 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 solenoid
valves is equipped with a pilot light that signals voltage pass-
ing through.
6.3 Burner start-up
Close the remote controls and position the selector 1)(Fig. 27) to
“
AUTO”.
Make sure that the lights or testers connected to the solenoids, or
the pilot lights on the solenoids themselves, indicate that no volt-
age is present.
If voltage is present, stop the burner immediately and check the
electrical connections.
When the limit thermostat (TL) is closed, the “ CALL FOR HEAT”
2)(Fig. 27) signal must be on and the burner starts the starting cy-
cle.
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.
