Users Manual 403
Dear Customer, Thank you for choosing an ARISTON boiler. We guarantee that your boiler is a reliable and technically sound product. This User’s Manual provides detailed instructions and recommendations for proper installation, use and maintenance. Remember to keep this manual in a safe place for future reference i.e. by the gas meter. Your local MTS Servicing Centre is at your complete disposal for all requirements.
1. GENERAL INFORMATION MTS (GB) Limited support the initiative. Your installer will give you, and show you how to use, a logbook which will give you important information about your boiler, and heating system. Please have this logbook to hand whenever you contact a service engineer or us. All CORGI Registered Installers carry a CORGI ID card, and have a registration number. Both should be recorded in your boiler Logbook.
2. OPERATING INSTRUCTIONS CAUTION Installation, start-up, adjustments and maintenance must be performed by a competent person only, in accordance with the current Gas Safety (Installation & Use) Regulations and the instructions provided. Improper installation may cause damage or injury to individuals, animals and personal property, for which the manufacturer will not be held liable. To ensure efficient and safe operation it is recommended that the boiler is serviced annually by a competent person.
does not light within the pre-set safety time limit, the red “B” L.E.D. will light up. To reset the ignition system, the reset button “A” must be pressed. Should the system fail to light a second time, check to make sure that the gas cock is open. If the problem persists, contact one of our Authorised Service Centres for assistance.
Installation with a room thermostat: - Turn the “C” selector knob to < >; - Turn on the power supply to the boiler by pressing the On/Off switch ”L”; the green L.E.D. will then turn on; - Turn the thermostat knob “H” to the highest temperature setting. - With this type of installation, the boiler is controlled by a room thermostat . Therefore, it runs until the ambient temperature has reached the temperature setting on the thermostat.
SHUTDOWN PROCEDURE I I To turn off the main burner, simply press the On/Off switch “L”; the green L.E.D. “I” will also turn off. As a precautionary measure, it is recommended that the gas cock located on the bottom of the boiler be turned off as well. L UT008Aa 3. TIME CLOCK Manual switch Summer and winter time setting Reset Enter the hours h Prog .
Automatic Operation Manual Operation Continuous Operation = ON = ON = Continuously ON = OFF = OFF = Continuously OFF The switching times correspond to the program entered. If the current switching mode is changed manually, the next switching time will be carried out automatically again according to the entered switching program. You can only return to automatic mode from the continuously-ON and continuouslyOFF switching modes by pressing the " " key.
Reading the programmed switching times Pressing the “Prog” key displays the programmed switching times until the first free memory location appears in the display “– – : – –”. If you now press the “Prog” key once again, the number of free memory Iocations will be displayed, e.g. “FR 18 ”. If all memory locations are occupied, the display “FR 00 ” appears. Changing the programmed switching times Press the “Prog” key repeatedly until the switching time you want to change is displayed.
4. USEFUL INFORMATION AND TROUBLESHOOTING BOILER SHUTDOWN The boiler unit is equipped with safety devices which intervene in certain situations to shutdown the boiler. Some of these situations are signalled by the unit and can be corrected by the user. SHUTDOWN DUE TO THE FAILURE OF THE BURNER TO LIGHT AUTOMATICALLY B This anomaly is indicated by the red “B” L.E.D. To reset the unit, press and then release the “A” button.
FLUE TEST FEATURE (only for authorised personnel) The “C” Summer/Winter/Flue Test selector knob can be set to < > to bypass temperature adjustment on the heating circuit for the purpose of analysing the fumes produced by combustion. To access this mode, open a water tap or taps so that the flow rate is no less than 8 litres per minute. Then press the “C” selector knob in and turn it from < > or < > to the < >. C UT008Aq 403 WARNING! The flue test feature eliminates the slow-light feature.
