1. 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.
Absence of a permanent pilot flame make it more
economical than conventional appliances.
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.
Green LED indicates burner condition.
