DEPENDING ON THE MODEL CHOSEN, THE WATER HEATER WILL COMPRISE THE
FOLLOWING COMPONENTS
FUNCTIONAL ASSEMBLIES
1. Incorporated draught diverter.
Ensures proper combustion even when the draught changes in the burnt gas
evacuation duct (flue). With its new design, the heater cover is free of gratings.
2. Heat exchanger.
Pure electrolytic copper with a caloric coating that ensures the highest
possible heat transfer to water.
3. Burner
Advanced technology that takes full advantage of the gas consumed
5. Ignition safety valve.
Electric system that only allows gas to leave the burners when the pilot light's
presence ensures it is ignited
6. Front gas control.
This can also be used to MANUALLY SELECT THE REQUIRED POWER.
7. Temperature selector.
Allows you to adjust the hot water temperature.
9. Special hydraulic device.
• Automatically starts the water heating mechanisms each time a hot water
tap is turned on. This is a GUARANTEE at the same time as the gas passage is
only open when water circulates through the exchanger.
13. Hot water connection: Flexible
14. Electronic Ionisation probe.
Used to ensure the burner's smooth operation through the ionisation
control. (see figure page 13)
15. Electrode ignition.
Provides continuous sparks to ignite the burner. (see figure page 13)
16. Temperature restrictor thermostat.
17. Ignition micro.
18. Control device for gas evacuation. (TTB)
Disconnects the heater if the combustion gas outlet is obstructed.
19. Battery box.
20 . Drainage valve.
21. Electronic control module.
