The operations to carry out are the following:
1.
Replacement of the nozzle (see table);
2.
Replacement of the gas label;
3.
Regulation of the slow ignition (refer to section 3.7 and the table
in 4.3)
-
Place the boiler in operation in accordance with the User’s
Manual.
-
Check the seal on the gas and water sides.
-
Check that the ignition operates correctly and visually check the
burner flame.
-
Check that the domestic hot water is being correctly produced
by drawing hot water. Check the rate of flow and/or temperature
of the water, depending on the case.
-
Check that the condensate drips without difficulty into the
discharge.

:
The thermal power is set in the factory at 70% of the maximum
power (the potentiometer corresponds to the value on the display). In
the event that this setting has to be changed, these steps should be
followed:
-
open the control panel after having unscrewed the plastic
fastening screws and lift up the rubber stopper protecting the
potentiometers (see section 3.7.1.). Rotate the potentiometer PR
to the desired point, checking the set thermal power on the
display (as described in section 3.6.3.) and on the table below.
Test:
-
Turn the selector knob “A” to the flue test position.
-
Do not draw hot water.
