It is recommended that the control- thermostat be set at approximately 60°C. For reasons of security, the water heater is provided with a high limit and safety thermostats. If the high limit thermostat operates, the burner will not fire until the water has cooled sufficiently to allow the thermostat to automatically reset. The water heater will then return to the control of the temperature regulator. If the safety thermostat operates due to high temperature the ignition sequence must be repeated after resetting the control. 3.3 Turning the water heater off For short periods: 1. Turn the temperature knob fully to the left and turn the ‘I/O’-switch in the ‘O’-position. For longer periods: 1. Switch off the supply voltage; 2. Close the gas tap in the supply line; 3. Close the water supply tap; 4. If there is danger of frost, drain the water heater. 3.4. Maintenance The water heater must be checked and cleaned regularly (at least once a year) by an accredited installer, so that proper operation is guaranteed. The bar burners, the pilot burner and the control and safety valves must also be checked. 4. FAULT FINDING 4.1 Fault finding USER No or insufficient hot water. Check whether the electricity is turned on. Check whether the gas supply is turned on. Reduce the water use or increase the control thermostat. yes Does the ON/OFF switch light up? yes Does the RESETswitch light up? yes Is the water heater in operation? yes no Check ifON/OFF switch inposition 1? yes Push RESET switch up to three times no Is the water heater in operation? no Problem solved yes ON/OFF switch i. position 1. Problem solved yes Is the water heater in operation? no no Consult your installer. 4.2 Fault finding INSTALLER Check gas connection and the electricity supply make sure that they are switched on. Problem solved yes Does the ON/OFF switch light up? yes Does the RESET switch light up? no Is the water heater in operation? no Check if ON/OFF switch is in position 1? yes no Push the RESET button up to three times Put ON/OFF switch in position 1. no Is the water heater in operation? yes no Problem solved Is the water heater in operation? yes Problem solved no no See detailed fault finding 4.3 Detailed fault finding INSTALLER Check voltage present at connection 1.
