Description of the heater

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,
• 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 in copper 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.
