start value is 3.300 revs/min (35 kW) and 3.700 revs/min (25-30 kW)
- Confirm the new value you have set by pressing ENTER.
MAXIMUM POWER ADJUSTMENT (P. HH) (Fig. 1.17)
- Turn the boiler OFF
- Select the parameter HH and wait for the boiler to come on
- Check that the maximum CO
"Checking combustion parameters") corresponds with the values
indicated in table 3.
If the CO proves to comply with the values in the table, proceed to
2
adjust the next parameter (LL - adjusting the minimum), if different
modify the value by turning the maximum power adjustment screw with
a screwdriver (clockwise to decrease) until you obtain a value contained
in table 3.
MINIMUM POWER ADJUSTMENT (P. LL) (Fig. 1.17)
- Select the parameter LL (with the boiler still OFF) and wait for the
boiler to come on.
- Check that the minimum CO
"Checking combustion parameters") corresponds with the values
indicated in table 4.
If the CO proves to be different from the values in the table, proceed to
2
adjust the parameter by turning the maximum power adjustment screw
after having unscrewed the protective cap (clockwise to increase) until
you obtain a value contained in table 4.
b
If the CO values do not correspond to the values in the
2
Multigas table, make further adjustments.
IGNITION SPEED (P. MM)
- Select parameter MM.
The boiler starts at the slow ignition speed.
- Turn the heating water selector to increase or decrease the fan speed.
MINIMUM HEATING ADJUSTMENT POSSIBILITY (P. 24)
- Select parameter 24
- Press the ENTER button to access the parameter value modification
function
- Turn the sanitary water selector to modify the minimum fan speed.
- Confirm the value you have set by pressing ENTER.
RANGE RATED MAXIMUM OUTPUT CH (FAN SPEED) - 23
- Select the parameter 23 by turning the encoder.
- Push ENTER button and modify the maximum fan speed as indicated
in the range rated table by turning the encoder.
- Push ENTER button to store the value.
The values just setted must be recorded on the last page of this manual.
Exit the CALIBRATION & SERVICE function by pressing ESCAPE.
The boiler returns to the "- -" (OFF) status.
To reset, press the button.

19 - GAS CONVERSION
It is easy to transform gas from one family to gas belonging to another
family even with the boiler installed.
This job must be done by professionally qualified personnel only.
The boiler is supplied to run on natural gas (G20) – see the product
rating plate for details.
The boiler can be transformed to use propane gas using a special kit.
Follow the instructions given here below for disassembly:
- Switch off the power to the boiler and turn off the gas cock.
- Remove the panel and casing.
- Lift up and rotate the instrument panel.
- Open the air box cover.
- Disconnect the air pressure switch wires.
- Unscrew the 2 screws (A) and remove the bracket and pressure switch
assembly.
- Disconnect the mixer gas ramp. Unscrew the clamp screws and
relative mixer springs to fan and then remove it.
- Loosen the plastic Venturi (C) - Fig. 1.19 - by levering from under the
teeth (BE CAREFUL NOT TO FORCE THEM) and press from the
opposite side until it is completely extracted from the aluminium shell.
- Replace the plastic Venturi with the one contained in the kit.
- Reassemble the mixer with the flap in a horizontal position and the
spacer springs placed at 120° as shown in the Fig. 1.20.
- Reassemble gas ramp and silencer, working vice versa.
- Refit the bracket and pressure switch assembly on the mixer and
reconnect the air pressure switch wires.
- Switch on the power to the boiler and turn on gas cock again.
- Check the number of times the fan turns.
- Fill in and stick on the accompanying transformation data label.
- Close the air box cover.
- Close up the instrument panel again.
- Reassemble the casing and panel.
Programme the "Gas type" parameter and regulate the boiler following
the instructions in the "Adjustments" section.
b
Transformation must be done by qualified personnel only.
b
After completing transformation, regulate the boiler again
following instructions given in the specific paragraph and
apply the new identification label from the kit.
General maintenance
Be particularly careful when handling the mixer: the clapet juts out
from the body so that the mixer must be laid on the air inlet side (flap
area) or make sure the clapet is inside the body if it has to be laid on
the clapet side.
The clapet must never have to bear the weight of the mixer.
Clean the Venturi from any dust with an aspirator during the annual
system cleaning. Check that flap and clapet are working correctly (all
open at rated flow, all closed at minimum flow).
