Wait for the burner to ignite.
The boiler will operate at maximum heating output and it will be possible to regulate the
combustion.
-
Remove the screw and the cover on the air distribution box (A-B)
-
Insert the analysis probe adapter (D) in the documentation envelope, into the hole for
the combustion analysis
- Insert the flue gases analysis probe inside the adaptor
-
Control the combustion checking that the CO
2 values match those in the table.
-
When the control is completed, remove the analyser probe and close the combustion
analysis sockets with the relative plugs and screw.
b
Leave the analysis probe adapter supplied with the boiler in the documentation
envelope.
b
If the value displayed is different, 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 REC10.

When the checks are completed:
- Set the boiler to "SUMMER" mode (only with storage cylinder) or "WINTER" mode
depending on the season.
-
Adjust the heat request temperatures according to the customer's requirements.
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
All controls must be carried out only by the Technical Assistance Centre.
5.13 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: access the technical parameters as explained in the section“
Accessing the technical parameters”.
-
set the SERVICE password
- in the TECHNICAL menu select COMBUSTION MONITORING with the "UP" and
"DOWN" keys , confirming the selection

After the conversion has been carried out, apply the new identification label contained in
the documentation envelope.
5.14 Range rated
This boiler can be adapted to the heating requirements of the system, in fact it is possible to
set the maximum delivery for the heating operation of the boiler itself:
- power up the boiler
-
access the technical parameters as explained in the section“ Accessing the technical
parameters”
- select RANGE RATED and confirm

Once the required output has been set (maximum heating), indicate the value on the self-
adhesive label supplied. For subsequent controls and adjustments, refer to the set value.
b
The calibration does not involve the ignition of the boiler.
The boiler is delivered with the adjustments shown in the technical data table.
Depending on plant engineering requirements or regional flue gas emission limits it is, however,
possible to modify this value, referring to the graphs below.
