ELECTRONIC WATER HEATERS (WITHOUT PERMANENT PILOT LIGHT)

- Prior checks

1. Make sure hot water taps are turned off.
2. Turn on the gas to water heater stopcock that is located where gas is supplied to the appliance.
3. Check that the 1.5 V batteries are correctly installed according to polarity (+ and -) and the safety seal has
been removed.
4. Check that they are sufficiently charged for the water heater to function.

- Manual selection of Burner Power

To ignite the appliance, turn the gas knob from the position
or maximum positions.
The gas knob allows you to select the water heater power, minimum ( ) or maximum
( ), and intermediate positions according to the hot water intensity required. Turn the gas
knob to the
full power. If the temperature is too high, for example in summer or when small volumes of not
very hot water are required, turn the knob to the right to
the power (and gas consumption) almost by half.

- Temperature selection

With the Temperature Selector you can easily gauge the water temperature by turning the selector to the
right to achieve a higher temperature, or to the left to obtain less hot water.
- Hot Water Service
- Once the previous settings have been selected, the water heater will start the process; turning on the hot
water tap will automatically generate continuous sparks through its ignition electrode and directly light the
burner.
- All the electronic models have an ionisation probe, which is immersed in the flame to
control it.
- If for any reason an issue has occurred in the gas circuit and the probe does not detect the
flame's presence, the ignition electrode will automatically generate sparks for a few seconds to
ignite the burner; in the event that the water heater does not turn on, it will be out of service.
- You must remove the cause or element that prevents the gas from reaching the water heater,
for example if the stopcock has been inadvertently turned off, worn out gas cylinder, etc.
