The firing rates has been obtained based on test boilers in accordance with EN267 standards and are indicative of matching the burner to the boiler.
For the correct operation of the burner, combustion chamber dimensions must be in accordance with current regulation. In case of non-compliance,
contact the manufacturer.

FLAME TUBE LENGTH
Flame tube length must be selected based on the specifications supplied by boiler manufacturer and, in any case, it
must be greater than the thickness of the boiler door included its insulation.
In case of boilers with flame inversion or front flue combustion chambers, it is necessary to insulate the area between
the flame tube and front door with refractory material. This protection material must not impede flame tube extraction.

2) Reset from lockout button + status lamp
The multicolor signal lamp in the lockout reset button (pos.2) is the key indicating element for visual diagnostics
and interface diagnostics.
In normal operation, the different operating states are indicated in the form of color codes; please refer to
electrical device handbook supplied with the present instructions.
After a non-alterable lockout, the red signal lamp in the lockout reset button (pos.2) lights up.
By pressing the lockout reset button (pos.2) for more than 3 seconds, the visual diagnostics of the cause of fault
can be activated; please refer to electrical device handbook supplied with the present instructions.
For close the diagnostics mode and for switch on the burner again, it is necessary to reset the burner control.
Press the lockout reset button (pos.2) for about 1 second (<3 seconds).
After a non-alterable lockout, the red signal lamp in the lockout reset button (pos.2) lights up.
For reset the control box press the lockout reset button (pos.2) for about 1 second (<3 seconds).
