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 before first firing

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 of the gas
train.
 Adjust the minimum gas pressure (Fig. 37) switch to the start
of the scale.
 Adjust the maximum gas pressure switch (Fig. 36) to the end
of the scale.
 Adjust the air pressure switch (Fig. 35) to the start of the scale.
 Purge the air from the gas line. Fit a U-type manometer
(Fig. 32) to the gas pressure test point on the sleeve. The
manometer readings are used to calculate the MAX. burner
power using the .
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 delivery
at the minimum.

Ignition pilot adjustment

Place the pilot and electrode as shown in Fig. 33.
The pilot works correctly at pressures ranging from 3 - 6" WC.
Important
To set the pilot without main burner operation, proceed as follows:
 Un-programmed unit (OFF Upr):
- When appears P0 flashing in the display, set air actuator
between 0° to 20°.
- Set the pilot pressure.
 Programmed unit (OFF):
- Set parameter 208 (Program stop) to 3 Interval 1 (Ph44).
- With the burner in the manual position, set air actuator
between 0° to 20°.
- Set the pilot pressure.
- When the setting is correct, set parameter 208 back to 0 =
deactivated.
