Technical instructions for use and maintenance
WARNING:
Before use, this appliance must be installed and adjusted by a
competent person according the technical instructions in this manual. No attempt
must be made to adjust this appliance for use with other gases.
• LIGHTING
THE PILOT
• Fully depress the control knob and turn it to the left from the
●
position to the
position (pilot setting).
• The pilot should light during this operation due to the action of the
piezoelectric spark igniter or electronic ignition.
• Hold this knob in this position for about 10 seconds after the pilot has lit.
If the pilot fails to light after having activated the piezoelectric spark igniter mechanism
or electronic ignition, this means that there is air in the gas pipes. In this case, allow
plenty of time for the pipes to be cleared of air, with the gas control knob at the pilot
setting.
★
Where there are long gas pipe runs, it may take up to 3 minutes.
• PREPARING THE HEATER FOR USE
Once the pipes are free of air and the pilot is alight, wait about 10 seconds for the
safety valve mechanism to be activated, the appliance is ready for use.
Turn the control knob anti – clockwise to one of the main burner settings.
• GAS CONSUMPTION SELECTION
You can choose between two different types of operation, depending on the hot
water outlet temperature required.
Economy Setting

Use this setting only when the ambient cold water supply to the heater temperature
is high (Normally summer continental use)
Full power setting (for normal use)
