and must be replaced.
1.3 Turning the heater on and off
Preliminary checks and operations
1. Make sure the hot water taps are closed.
2. Open the gas supply cock to the heater, located at the gas connection to the unit.
3. Check that the 1.5 V batteries are properly installed with the correct polarity (+/-). To
replace the batteries, see (3.4 Replacing the batteries).
4. Also verify that the batteries are sufficiently charged for heater operation.
1.3.1 Turning the unit on
Turn the knob to the required water heating level.
The unit will begin operating every time hot water is drawn.

1.3.2 Turning the unit off
The burner goes off automatically when hot water is no longer demanded.
To use the unit again, no action is required.
To completely shut off the unit, place the knob in the () position.

If the water heater will not be used for an extended period of time, close the gas cock
supplying the unit.
If the unit will be inactive for an extended period of time during the
winter, all water should be removed to avoid ice damage.

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 mini-
mum, maximum, and intermediate positions, depending on the required heating power.
If the knob is turned counterclockwise, the unit will operate 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 increase the temperature, or counter-
clockwise 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 generated 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 malfunction 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 preventing the gas from reaching the
heater, e.g., inadvertent 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.
