Wait for the burner to ignite.
The boiler will operate at maximum heating output and it will be possible to
regulate 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
to those indicated in the multigas table.
- Once checking completed, remove the analyser probe and close the
combustion analysis sockets with appropriate caps and screw.
b
If the value displayed is different from the one shown in the
multigas table DO NOT OPERATE ANY ADJUSTMENT ON THE
GAS VALVE, please contact the Technical Assistance Centre.
b
The gas valve DOES NOT REQUIRES ADJUSTMENTS and the
possible tampering causes a malfunction or failure of the boiler.
b
When the combustion analysis 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; green and red LEDs are off.
A
When the checks are completed:
- set the boiler to HOT WATER ONLY (only if connect a water tank) or
HEATING AND HOT WATER mode depending on the season
- regulate the heat request temperature values according to the customer's
needs.
IMPORTANT
The combustion analysis 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 exclusively by the Technical
Assistance Centre.
5.14 Range rated
This boiler can be adapted to the system thermal requirements as it is possible
to set the maximum flow rate for the boiler operation in heating mode:
