2.4

Description of appliance

Operating convenience, as the heater is ready to operate by 
simply pressing a switch.

Heater for wall-mounting

Ignition by electronic device triggered when the water valve 
opens

Gauge to display temperature, burner operation and 
malfunctions

Temperature sensor to monitor the water temperature at 
the heater output

Great savings in comparison with conventional heaters, 
due to the possibility of power adjustment and no 
permanent pilot flame

Natural gas/LPG burner

Semi-permanent pilot burner which only functions during 
the period between the opening of the water valve and the 
ignition of the main burner

Heat exchanger without tin/lead covering

Water valve in fibreglass-reinforced polyamide, 100% 
recyclable

Automatic adjustment of the water flow by means of a 
device which permits a constant flow to be maintained in 
spite of variable pressure supplies

Gas flow adjustment proportional to the water flow to 
maintain a constant high temperature.

Safety  devices: 
– Ionisation probe to check for accidental extinction of 

the burner flame

– Flue gas safety device which turns off the heater in case 

of inadequate combusted gas evacuation conditions

– Temperature limiter which prevents overheating of the 

heat exchanger

2.5

Accessory (not supplied with the appliance)

Conversion kit from natural gas to butane/propane and 
vice-versa.
