Manual selection of Burner Power
To ignite the appliance, turn the gas knob from the position
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 is too high, for example in summer or if a small volume of not very hot water is required, turn the knob to the position
(small flame), reducing 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 auto-
matically 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.
• The water heater block is deactivated by turning on and off the hot water tap;
