IMPORTANT! The piping and heating elements must be thoroughly cleaned with running water before 

starting the boiler. This operation is important to prevent the deposit of foreign bodies in the various 

boiler compartments, with the risk of compromising its operation. For this purpose it may be useful to 

install a dirt separator filter 

 

Pressure check 

 

To display the heat chamber pressure, press and hold key 5 on the display for a few seconds. Digits 

indicating  the  pressure  (letter  b  =  bar)  will  appear  on  the  second  row.  The  ideal  pressure  must  be 

between 1 and 1.5 bar. If the pressure exceeds 2 bar, the stove will enter the alarm mode. Moreover, 

the system supplied to the stove is equipped with a mechanical relief valve with a fixed calibration of 3 

bar  which  automatically  drains  the  system  if  it  reaches  this  pressure  (in  case  of  "not  standard" 

installations, provide a drain pipe). 

 

System refill 

 

It is possible to proceed with the system refill once the hydraulic connections to the system piping have 

been completed. To do this it is necessary to open the tap until the gauge index will have reached 1 

bar.  During  this  operation  it  is  recommended  to  bleed  the  internal  air  through  the  vent  valve  "jolly” 

located under the cover of the boiler and through the radiator vents. This operation is to be carried out 

with the boiler switched off. Once the system has been bled and has reached the pressure indicated, it 

is then  possible to proceed with the boiler  start up.  Occasionally check that the system pressure is 

always kept between 0.5 and 1.5 bar. 

 

IMPORTANT! If for any reason the pressure should increase or decrease, it is advised to troubleshoot 

and reset the pressure. 

 

PRESSURE TOO LOW: open the load tap until the desired pressure is reached (1 bar).  

 

PRESSURE TOO HIGH: let some water leak out from the safety valve by rotating the specific knob until 

the desired pressure is reached (1 bar); next place the safety valve in its initial position, or let water leak 

out through the radiators air vent. 

 

Warning! 

 

 

 

Let water circulate for a few minutes so as to allow all the air to be bled through the jolly valve. To 

make this operation easier, it is advised to operate the pump by turning the switch on and off, at 

approx 10 second intervals.  

 

Check the pressure indicated on the gauge. If it has decreased then bring it back between 0.5 and 1 
bar using the refill tap.  

 

It is good practice to predispose an air valve on all the heating elements. 

 

Avoid operating the circulation pump with the boiler empty.  

 

N.B.  If  the  system  is  not  completely  bled  the  boiler  may  not  work  correctly  and  the  alarm  “PRESS 

WATER” will appear. 

 

System type 

 

The boiler allows the radiators to be heated autonomously in a dwelling of approx 380 cubic metres.  

 

AUTONOMOUS OPERATION  

The boiler can operate autonomously by connecting directly to the heating system through the radiators 
or underfloor heating. The power ratings signalled refer to ideal systems (aluminium radiators, insulated 

copper pipes). Substantial differences decrease the heatable metrature.  

 

INTEGRATED OPERATION  

It is possible to install the boiler in parallel to another heat generator with either open or closed circuit.
