When the checks are completed:
- set the boiler to
HOT WATER ONLY
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
In case of a low temperature system we recommend carrying out the
efficiency test by taking hot water setting the boiler STATE to HOT
WATER ONLY
, 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 exclusively by the Technical
Assistance Centre
.

The calibration does not cause the boiler ignition.
The boiler is supplied with the settings indicated in the multigas table.
It is nevertheless possible, 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.
