Parameter
Settings.
• Check minimum gas pressure is suitable for selected gas:
Minimum gas pressure is determined with boiler operating
at high fire and any other appliances connected to same fuel
source operational as well (whole house load)
Gas A (NG) = 3.5" (8.7 mbar)
Gas E (LPG) = 8.0" (19.9 mbar)
• Place supplied label with indication of gas type
close
to the data plate of boiler replacing the original.
• Perform Automatic Calibration Function -
Section 9.8.

IMPORTANT INFORMATION
A. If display shows fault
E118
(low pressure in
hydraulic circuit) open filling tap on appliance and
restore correct pressure.
B. If gas recognition function is interrupted due
to fault (e.g.:
E133
no gas) press
to
reset. Then press
and
(for at least
6 seconds) to restart the function again.
If gas recognition function is interrupted due to

operation to Natural gas.
D. Type is being established.
9.9 Manual Calibration Function:
Manual Calibration phase starts at the end of the
Automatic Calibration.
The Display shows the boiler power and adjustment
of the CO2 value (parameter setting) during Manual
Calibration sequence.
The process begins at minimum power.
A. After Automatic Calibration sequence with
flashing together on the display, you can adjust
minimum power combustion by pressing
to
lower % CO
2
, and
to raise % CO
2
.
B. When minimum power combustion is in the
specified range, press
and then
to reach
ignition power.
C. Press
to adjust ignition power combustion.
Press
to lower % CO
2
, and
to raise % CO
2
.
D.
When ignition power combustion is in the specified
range, press
and then
to reach maximum
power.
E. Press
to adjust maximum power combustion.
Press
to lower % CO
2
, and
to raise % CO
2
.
F. When maximum power combustion is in the
specified range,
press
to exit Manual Calibration
Function.
