3 - Adjustments

START CONDENS Kis boilers are intended for use with methane gas
(G20) and are already factory set as specified on the rating plate.
If adjustments have to be redone, for example after extraordinary
maintenance, after the gas valve replacement or after conversion
from methane gas to LPG and vice versa, the following procedures
must be followed.
9 The adjustment of the maximum and minimum output, and slow
ignition, must be made in the sequence indicated, and by quali-
fied personnel only.
• Disconnect the power supply to the boiler
• Turn the heating water temperature selector to its maximum ()
• Unscrew the fixing screws of the hatch on the terminal board cover
• Insert jumpers JP1 and JP3
• Power up the boiler
• The display shows "ADJ" for about 4 sec.
Proceed with the modification of the following parameters:
• Absolute maximum / DHW
• Minimum
• Maximum heating
• Slow ignition
As described below:
• Turn the heating water temperature selector to set the desired
value
• Press the CO button using the supplied screwdriver (A - fig. 16)
and move on to the calibration of the next parameter.
9 Live electrical parts.
The following icons are displayed:
• during the absolute maximum/DHW calibration
• during the minimum calibration
• during the maximum heating calibration
• during the slow ignition calibration
End the procedure by removing the JP1 and JP3 jumpers to store
the set values.
The function can be terminated at any time without saving the set
values while maintaining the initial ones:
• Removing jumpers JP1 and JP3 before all 4 parameters have
been set
• Turning the mode selector to OFF/RESET
• Removing the mains voltage 15 minutes after its activation.

9 The calibration does not entail the ignition of the boiler.
9 By rotating the heating selector knob, the number of revolutions
expressed in hundreds (e.g. 25 = 2500 rpm) is automatically
displayed.
The calibration parameter display function is activated with the se-
lector on summer or winter by pressing the CO button (A - fig. 16) on
the board regardless of whether or not there is a heat request. The
function cannot be activated if a remote control is connected.
When this function is activated, the calibration parameters each ap-
pear (in the order shown below) for 2 seconds. The relative icon
is indicated in line with each parameter, and the fan rotation value

3.1 - Gas valve calibration
• Power the boiler
• Open the gas tap
• Turn the mode selector to OFF/RESET
• Remove the housing and turn the control panel
• Undo the fixing screws of the cover to access the terminal board
• Press the "CO" button (A - fig. 16) once
9 Live electrical parts.
• Wait for the burner to fire. "ACO" is displayed. The boiler operates
at the maximum heating output. The "combustion analysis" func-
tion is active for a time limit of 15 minutes; the burner shuts down if
an outlet temperature of 90° C is reached. It will ignite again when
the temperature falls below 78° C.
• Remove the screw (A - fig. 18) and cover (B - fig. 18) on the air
distribution box
• Insert the analysis probe adapter, found in the documentation en-
-20
velope, into the hole for the combustion analysis (C - fig. 18)
• Insert the flue gases analysis probe inside the adaptor
• Press the "combustion analysis" button a second time to reach the
rpm corresponding to the maximum DHW output (see the multi-
gas table)
• Check the CO
not comply to what is reported in the table, act on the max adjust-
ing screw of the gas valve (A - Fig. 19)
• Press the "combustion analysis" button a third time to reach the
rpm corresponding to the minimum output (see the multigas table).
• Check the CO

• Turn the control knob to exit the "combustion analysis" mode
• Pull out the flue gas analysis probe and replace the plug.
• Close the instrument panel and reposition the cover
• The "combustion analysis" function is automatically disabled if the
card generates an alarm. In the event of an anomaly during the
combustion analysis phase, perform the reset procedure.

4 - Range rated

This boiler can be adapted to the heating requirements of the sys-
tem, in fact it is possible to set the maximum delivery for heating
operation of the boiler itself:
• Disconnect the power supply to the boiler
• Turn the heating water temperature selector to its maximum ()
• Remove the housing and turn the instrument panel (refer to previ-
ous chapters for the detail of the figures)
• Unscrew the fixing screws of the hatch on the terminal board cover
• Insert the jumper JP1
• Power up the boiler
The display shows "ADJ" for about 4 sec.: it is then possible to
change the maximum heating value by means of the heating water
temperature selector and the CO button in order to set and confirm
the desired value.
The icon will appear on the display
Finish the procedure by removing the jumper JP1 to store the set
values.
