INSTALLATION INSTRUCTIONS

19.1 GAS VALVE CALIBRATION FUNCTION

Note:

The function is automatically deactivated after a period of 15 minutes, at the end of which the electronic board returns to 
its operating status prior to the activation of the function or prior to reaching the set maximum temperature.

To simplify calibration of the gas valve, the calibration function may be set directly 

on the boiler control panel as follows:

a)

  hold down the buttons 

 and 

 together for at least 6 seconds; 

b)

  after about 6 seconds, the symbols 

 lash;

c)

  the display shows, at intervals of one second, “

100

” and the 

flow temperature

.

  In this phase, the boiler works at the maximum heating output (100%). 

d)

 press 

+/-

   to immediately set the power of the boiler (100% or 0%);

e)

  adjust the 

“Pmax/Pmin”

 screw (igure 10) to set the burner pressure value as 

described in table 1.

  To adjust pressure at maximum power, turn the “

Pmax

” screw (ig. 10) clockwise 

to increase or anti-clockwise to decrease pressure at the burner.

  To adjust pressure at minimum power, turn the “

Pmin

” screw (ig. 10) clockwise 

to increase or anti-clockwise to decrease pressure at the burner.

f)

 press 

+/-

 to gradually set the desired power level (interval = 1%).

Press the button   to leave the function.
