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.
- 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 CO2 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.
- Leave the analysis probe adapter supplied with the boiler in the
documentation envelope.

If the value displayed is diff erent 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 REC10
.

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 STATUS 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.

This boiler can be adapted to the heating requirements of the system, in
fact it is possible to set the maximum delivery for heating operation of the
boiler itself:
- Power up the boiler
- access the technical parameters as explained in the section“ Accessing
the technical parameters”.
