Commissioning
Setting the flame
Setting the minimum pressure
If the flame has been detected and stabilised, the control unit sets the burner to minimum power
as soon as it receives the regulation authorisation.
- Check the combustion values (CO, CO
2
, soot test). If necessary, adjust screw
N
on the valve
(see page16).
- Read the ionisation current value.
- Read the gas flow rate on the gas counter.
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.
The servomotor reacts in real time. This is why the combustion values must be continuously
monitored.
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
V
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°.
Definitive limitation of the minimum output position
Using the "manual output control" function, reduce the burner output to the minimum output. If
necessary, limit the minimum output position, in the same way as for the maximum output.
Specific function: ignition checking
If the ignition position has been modified, it is possible to carry out a new burner start-up to check
the new ignition position, without having to quit the settings menu.
To do this, after modifying the ignition position, position the cursor on the
symbol, and initiate
the new start-up using the
key.
