2.4 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 heat-
ers, 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
• Combustion chamber 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 main-
tained 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 con-
ditions
– Temperature limiter which prevents overheating of
the combustion chamber
2.5 Special accessories
• Conversion kit from natural gas to butane/propane
and vice-versa
