Once the required output has been set (maximum heating), indicate
the value on the self-adhesive label supplied. For subsequent con-
trols and adjustments, refer to the set value.

The calibration does not entail the ignition of the boiler. By rotat-
ing the heating setpoint selector knob, the value expressed in
hundreds (e.g. 25 = 2500 rpm) is automatically displayed.
The boiler is supplied with the adjustments shown in the table. De-
pending on plant engineering requirements or regional flue gas
emission limits it is, however, possible to modify this value, referring
to the graphs below.

5 - Conversions from one type of gas to another
The boiler is designed to operate with methane gas (G20) according
to the rating plate. It may however be converted from one type of gas
to another by using the special kits supplied on demand.
• Methane conversion kit
• LPG conversion kit.
9
The conversion must be carried out solely by the Technical As-
sistance Service or by
r
personnel authorised by even when
the boiler is already installed.
9
Refer to the instructions supplied with the kit for assembly.

After conversion, adjust the boiler again following the indications
in the specific section and apply the new identification label con-
tained in the kit.
Conversion from a family gas to other family gas can be performed
easily also when the boiler is installed.
This operation must be carried out by professionally qualified per-
sonnel. The boiler is designed to operate with methane gas (G20)
according to the product label. It is possible to convert the boiler to
propane gas, using the special kit.
For disassembly, refer to the instructions provided below:
• Disconnect the boiler from the electricity supply and turn off the
gas tap
• Remove in the following order: air distribution box cover and casing
• Remove the fixing screw of the instrument panel
• Turn the instrument panel forward

• Remove the nozzle (B - fig. 20) and replace it with the one in the kit
• Fit the gas valve again
• Extract the silencer from the mixer
• Open the two half-shells by levering on the relative hooks
• For 25 KIS models: Replace the air diaphragm (C - Fig. 21) posi-
tioned inside the silencer
• For 29 KIS models: insert the air diaphragm (C - Fig. 21) inside
the silencer
• Reassemble the air distribution box cover
• Power-up the boiler and open the gas tap.
Adjust the boiler as described in chapter "Settings" referring to the
