Combustion check
To carry out the combustion analysis, proceed as follows:
- power the boiler electrically by setting the main system switch to "ON"
- set the boiler to OFF

- The chimney sweeper function can also be activated by pressing the SW1 key on
the electronic board AKM (this requires removing the plug (C) from the cover of the
instrument panel to access the electrical components).
b
It is not possible to activate the combustion control function with the OT device con-
nected.To carry out the flue gas analysis, disconnect the OT connection wires and
wait 4 minutes, or disconnect the power supply and restore voltage to the boiler.

The chimney sweeping function is normally carried out with the three-way valve
positioned on heating. It is possible to switch the valve to domestic hot water
generating a domestic hot water heat request at maximum output while the
function itself is being carried out. In this case, the temperature of the domestic
hot water is limited to a maximum of 65°C. Wait for the burner to ignite.
The boiler will operate at maximum heating output and it will be possible to regulate the
combustion checking that the CO
values correspond to those indicated in the multigas table.

b
If the value displayed is different to that shown in the technical data table, DO
NOT CARRY OUT ANY ADJUSTMENTS OF THE GAS VALVE, ask for help from
the Technical Assistance Centre.
b
The gas valve DOES NOT need adjusting and any tampering with it causes the
boiler to operate irregularly or even not at all.
b
When the sweeper function is in progress all the heat requests are inhibited
and a scrolling message appears at the foot of the main page of the REC10CH.
When the checks are completed:
- set the boiler to "SUMMER" or "WINTER" mode depending on the season
- regulate the heat request temperature values according to the customer's needs.
IMPORTANT: The chimney sweep function is active for a time limit of 15 minutes; the
burner shuts down if an outlet temperature of 95° C is reached. It will ignite again when the
temperature falls below 75° C.
b
In the case of a low temperature system we recommend carrying out the efficiency
test by taking hot water setting the boiler STATE to SUMMER, opening the hot water
tap to full capacity and setting the temperature of the domestic hot water to the
maximum.
b
All controls must be carried out only by the Technical Assistance Centre.

Gas conversion
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 personnel.
The boiler is delivered to operate with methane gas (G20).
To convert the boiler to propane gas (G31)proceed as follows:
- set the SERVICE password
- select TECHNICAL

The faults description screen is automatically displayed once the display illumination time
has elapsed without any button being pressed.
Reset function
To restore boiler operation, press "OK" from the error message screen. At this point, if the
correct operating conditions have been restored, the boiler will restart automatically. There
are a maximum of 3 consecutive attempts at a release by the REC10CH. In case of all the
attempts are exhausted the definitive fault E099 occurs on the display. The boiler will need
to be unlock by cutting off and reconnecting the electrical supply.

If the reset attempts do not activate the boiler, contact the Technical Assistance
Centre.

For fault E041:
the fault code "E041 - WATER TRANSDUCER PRESS OK FOR AUTO FILL" for a transitional
time of 30 sec during which it is possible to start the semi-automatic loading procedure, pressing
the "OK" key to fill the system (the procedure can only be started in SUMMER or WINTER).
