IMPORTANT: This heater is not thermostatic.
Note: It is advisable to adjust both the power and the water temperature to the
minimum value necessary to cover your requirements. This will save energy and
prolong the life of the appliance, reducing scale deposits on the heat exchanger.
Switching off the water heater
When the hot water tap is turned off, the heater will stop automatically.
To switch off the heater completely, press the ON-OFF button (3).
IMPORTANT: When the heater is switched on for the first time, or if it has
not been used for a certain time, or when a new gas bottle is installed, the
appliance may fail to ignite due to the presence of air in the gas pipes. If
this happens, the heater will 'LOCK OUT' and the red LED (4) will be
displayed.
Occasionally, the heater may fail to ignite due to excessively windy
conditions or other adverse atmospheric conditions, causing 'LOCKOUT'.
Insufficient gas pressure (faulty regulator) or fluctuations in voltage may
also cause 'LOCKOUT'.
To RESET the heater press the ON-OFF button to switch off then depress the
ON-OFF button to restart. The red LED should now be off and the heater
should ignite when the hot tap is opened.
If the heater locks out persistently, call your installer or the MORCO on
01482 325456 for details of your nearest service agent.
