2.4 Adjustments
Manual setting of burner power
Use the power adjustment knob (ref. 3 - fig. 1) to select the water heater power, minimum
or maximum and intermediate positions depending on the required water heating level.

Turn the knob anticlockwise and the unit heats the water at maximum power. If the tem-
perature is too high, for example in the summer, or when a reduced flow of not very hot
water is necessary, turn the knob clockwise. This reduces the power (and gas consump-
tion). In the position
Temperature setting
The water temperature can be easily set with the temperature selector: turn it to the right
to increase the temperature, or to the left to decrease.
Faults
After making the adjustments described above, the water heater is ready to operate in
completely automatic mode. When a hot water tap is opened, an intermittent discharge
is generated on the ignition electrode, which causes lighting of the burner.
All the electronic models have an ionisation electrode inserted in the burner to control
correct flame presence. In case of malfunction or no gas with subsequent burner shut-
down, close the hot water tap.
It is then necessary to eliminate the cause or the element preventing the gas from reach-
ing the water heater, e.g. inadvertent closing of the gas cock, empty gas cylinder, etc.
Water heater shutdown status is deactivated by closing and opening the hot water tap.
Repeat the operation if the delivery of hot water is not restored after eliminating the cause
and opening the hot water tap. If the fault persists, contact the After-Sales Technical
Service.
