3.6 Adaptation for other gases 
and burner adjustment

Adapting the boiler from methane 
to LPG

- Remove the main burner
- Remove main burner nozzles from 
main burner replacing them by new 
gas type correct diametre nozzles.
WARNING! Always install copper 
gaskets.
- Re-install the main burner
- On the electronic board, switch J 
MET-LPG jumper to LPG position 
(see pic. 22).

Adapting the boiler from LPG to 
methane

- Remove the main burner
- Remove main burner nozzles from 
main burner replacing them by new 
gas type correct diametre nozzles.
 WARNING! Always install copper 
gaskets.
- Re-install the main burner
- On the electronic board, switch J 
MET-LPG jumper to MET position 
(see pic. 22).

A) Max power adjustment

- Check gas mains supply pressure 
(refer to NOZZLE-PRESSURE chart 
§ 2.4)
- remove plastic cap C (pic. 23), 
which is positioned on top on the 
modulating coil and protects gas 
valve pressure adjusting nut and 
screw
- Connect a manometre to V check 
in pic. 24
- Adjust R screw in pic. 25 to MAX 
by rotating it fully clockwise
- Select “winter” boiler operation
- Start boiler to “chimney sweep” 
mode (see § 3.2.10.1)
- Turn nut K (external) clockwise in 
order to increase nozzle pressure 
and vice-versa (pic. 26)
- In LPG-fueled boilers, turn brass 
nut K fully clockwise.

B) Min power adjustment

- Disconnect the electrical wiring to 
modulation coil (M in pic. 24)
- Turn the burner on and check MIN 
pressure according to NOZZLE-
PRESSURE chart (§ 2.4)
- In order to adjust pressure, hold 
nut K still by means of a 100 mm 
tool, turn screw W clockwise to 
increase and counter-clockwise to 

decrease gas pressure (pic. 26)
- Re-connect electrical wiring to 
modulation coil.

C) Final settings

- Turn P ACC screw (S in pic. 
25) to middle set point, exit the 
“chimney sweep” mode and check 
burner ignition to be correct and 
silent: should it result incorrect or 
noisy, increase or decrease ignition 
power by acting on P ACC adju-
ster (clockwise to increase, counter-
clockwise to decrease)
- Re-check for correct min and max 
gas valve pressure values
- Adjust as necessary
- Install plastic protective cap C
- Close gas pressure checks
- Check for gas leaks.
