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
Setting the temperature
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 it.
Faults
After making the above adjustments, the water heater will be ready to work in completely
automatic mode. When a hot water tap is turned on, an intermittent discharge is gener-
ated on the ignition electrode, which causes lighting of the burner.
All electronic models have an ionisation electrode fitted in the burner to control the cor-
rect presence of flame. In case of a fault or no gas feed with consequent burner shut-
down, the hot water tap must be turned off.
It is therefore necessary to eliminate the cause of no gas reaching the water heater, e.g.
inadvertent closing of the gas cock, gas cylinder empty, etc.
Water heater shutdown is deactivated by turning the hot water tap off and on.
Repeat the operation if there is still no hot water after eliminating the cause and turning
on the hot water tap. If the problem persists, contact the After-Sales Service.
cod. 3541C702 - Rev. 01 - 06/2014
Make sure the hot water taps are closed.
Open the water heater gas supply cock, located on its gas connection.
Make sure the 1.5 V batteries are properly fitted, with the correct polarity (+ and -).
For their replacement see *** 'Replacing batteries' on page 11 ***.
Also make sure the batteries have enough charge for water heater operation.
