The control unit awaits the regulation
authorisation.
Setting the minimum pressure.
If the flame has been detected, the control
unit sets the burner to minimum power as
soon as it receives the regulation
authorisation.
- Adjust the gas pressure on the required
output, using the regulator on the gas valve.
Monitor the combustion values continuously
as you do so (CO, CO2, soot test). If
necessary, adjust the airflow.
- To do this, modify the position of the
servomotor to minimum power. Proceed as
described, in the paragraph "Modifying the
value of a servomotor position setting"
- Precautions: when modifying the setting
value, the servomotor will move in real time.
As a consequence, the combustion values
must be constantly checked.
Modification of the air flow via the
"manual output control"
The "manual output control" function allows
the burner output to be modified.
To do this, position the cursor on the
corresponding line on the display and
confirm with the key. It is then possible to
adjust the burner output upwards or
downwards using the , keys.
Setting the maximum output
Slowly increase the burner to the maximum
output using the "manual power control"
function. At this point, adjust the gas flow
using the regulator on the gas train.
The preset limit values for the minimum
output and the maximum output cannot be
exceeded. If necessary, exit the "manual
output control" function again using the
key and modify the limit value for the
maximum or minimum output.
Definitive limitation of the maximum
output position
Limit the maximum opening of the air flap
according to the position determined for the
maximum output. In this example, the new
position determined for the maximum output
is below the value set manually. Using the
"manual output control" function, it is now
possible to reduce the burner output, but
this cannot be set above the new maximum
position, which here is 50°.
