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
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

- 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.
