Technical Characteristics and Dimensions
1. 1
General Description
The appliance is easy to operate as it is ready to use at the
press of a button.
Guaranteed safety provided by:
- Gas-tight ionisation detector that prevents escape of gas
if there is no flame.
- Flue gas safety device that switches off the appliance if
the flue is not functioning properly.
- Temperature limiter which protects the heat exchanger
against overheating.
Electronic ignition controlled by opening of water valve.
Output modulation, absence of a permanent pilot flame and
absence of batteries make it more economical than
conventional appliances.
Hydrodynamic generator produces the necessary electrical
power for ignition and appliance monitoring.
Semi-permanent pilot flame functions only during the time
between opening of the water valve and activation of the
main burner.
Heat exchanger has no tin/lead lining.
Automatic water valve made of glass-fibre reinforced
polyamide, 100% recyclable.
Automatic control of water flow maintains constant flow rate
even with fluctuating supply pressure.
Proportional adjustment of gas and water flow rates in order
to ensure an even temperature gradient.
Green LED indicates burner condition.
