The value indicated on the display is expressed in revs min/100 (example 3600
= 36).
The value set during this operation automatically modifies the maximum value
of parameter 24.
VENTILATOR IGNITION SPEED (P. SP)
- Select parameter SP
- Press the ENTER button, then modify the value of the parameter by turning
the sanitary water temperature selector. The standard slow start value is
3700 revs/min
- 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", page 23) corresponds with the values
indicated in table 3.
If the CO proves to comply with the values in the table, proceed to adjust the
2
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", page 23) corresponds with the values
indicated in table 4.
If the CO proves to be different from the values in the table, proceed to adjust
2
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.

19 - GAS CONVERSION

It is easy to convert from one gas family to another even after the boiler has
been installed. This operation must be performed by professionally qualified
staff. The boiler is designed to work with natural gas or LPG. The product plate
indicates which fuel it has been fitted out to use.
It is possible to convert the boiler from one kind of gas to the other using kits
which can be supplied on request:
- natural gas to LPG conversion kit
- LPG to natural gas conversion kit.
To disassemble, proceed as follows:
- disconnect the boiler from the power supply and close the gas tap
- remove the components to access to the internal parts of the boiler (Fig.
1.18-1.19)
- remove the gas ramp (A)
- remove the nozzle (B) contained inside the gas ramp and replace it with the
one contained in the kit
- remount the gas ramp
- remount components previously removed
- power the boiler and open the gas tap (with the boiler working, check there
are no leaks in the gas supply circuit).
