1.4 Settings

1.4.1 Setting the burner power manually
Use the knob (3 fig. 1) to select the heater power. You
may choose between the minimum, maximum, and in-
termediate positions, depending on the required heating
power.
If the knob is turned counterclockwise, the unit will ope-
rate at maximum power. If the temperature is too high,
for example in the summer, or if you need a reduced
flow of not very hot water, turn the knob clockwise. This
reduces the power, and therefore the gas consumption.
In the ● position, the unit is turned off.

1.4.2 Setting the temperature

Turn the water temperature selector clockwise to incre-
ase the temperature, or counterclockwise to decrease it.

1.5 Faults

Once the adjustments described above have been made,
the heater is ready to operate automatically. When a hot
water tap is opened, an intermittent discharge is genera-
ted on the ignition electrode to light the burner.
All electronic models have an ionization electrode built
into the burner to monitor flame presence. If a malfun-
ction or lack of gas causes the heater to turn off, close
the hot water tap.
It is then necessary to eliminate the fault or obstacle pre-
venting the gas from reaching the heater, e.g., inadver-
tent closing of the gas cock, empty gas cylinder, etc.
To reactivate the heater, close and open the hot water
tap.
If no hot water is produced after eliminating the cause
and opening the hot water tap, repeat the process.
If the problem persists, call the technical support center.
