combustion analysis button SW1
Wait for the burner to ignite.
The boiler will operate at maximum heating output and it will
be possible to check the combustion.
- Insert the analyser probes in the specific positions on the air
distribution box, after removing screw (
A
) and cap of the flue
gases analysis socket ( B ).
- Perform the combustion check verifying that the CO
2
values
correspond to those indicated in section-2 “Technical Data”.
- Once completed, remove the analyser probe and close
the combustion analysis test points, using the previously
removed cap and screw.
b
Should the readings be significantly different from the
values declared in the technical data table;
do not
attempt to carry out any adjustment of the gas valve.
Please call the Vokera technical Helpline for assistance
and further advice.
b
The gas valve is non-adjustable and must not
be tampered with. Tampering with the gas valve
will result in the malfunction of the appliance and
possible damage to components.
b
When the sweeper function is in progress all the heat
requests are paused and a scrolling message appears
at the foot of the main page of the REC10; green and
red LEDs are off.
A
B
When the checks are completed:
- set the boiler to “SUMMER” or “WINTER” mode depending
on the User’s requirements
- regulate the heat request temperature values according to
the customer’s needs.
IMPORTANT
The sweeper 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 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.
6.13 RANGE RATED
This appliance can be ‘range-rated’ if necessary, and this
function enables a bespoke maximum heat output to be set
according to the specific application:
- access the technical parameters as explained in section 8
- select RANGE RATED

INSTALLER
CALIBRATION
INSTALLATION
- set the desired heating maximum value (rpm) with the “up”
and “down” keys, confirming the selection
RANGE RATED
5100
RPM
- once the desired power is set (maximum heating) note
the value onto the supplied self-adhesive label. For further
checks and adjustments refer to the set value.
b
The calibration does not affect the boiler ignition.
The boiler is supplied with the settings indicated in the
technical data (section 2).
Nonetheless, it is possible to alter or limit the appliance
output, according to the system requirements or the regional
regulations on the combustion gas emission limits, to set that
value by referring to the graphs below.
