Page 3: Warning
General information for fitters, maintenance technicians and users This INSTRUCTION MANUAL, which is an integral and indispensable part of the product, must be handed over to the user by the fitter and must be kept in a safe place for future reference. The manual must accompany the boiler should it be sold or its possession transferred. This boiler is designed for connection to a central heating system (all models) and to a hot domestic water system (models CTN and CTFS only). -
Page 4: Rapid Operating Instructions
RAPID OPERATING INSTRUCTIONS These instructions can be followed for rapid ignition, regulation and immediate use of the boiler, provided it has been installed by an authorized fitter, started up for the first time and set up for correct operation. If the boiler is equipped with other accessories, these instructions are not sufficient to ensure correct operation. Reference must be made to the full instructions for the boiler and all mounted accessories. -

Page 9: Operation
1.2.2. Operation CENTRAL HEATING Use the regulation knob (11, pic. 1) to set the temperature in the central heating system. The temperature setting range is 35-78°C (from the counter-clockwise limit position to the time limit position). The CH temperature can be read from lights 2÷7 (pic. 1) on the control panel. To prevent frequent ignition and switching off in heating mode, the boiler has a 4-minute waiting time between subsequent ignitions. -
Page 10: External Temperature Probe Operation (Optional)
In boilers with an external heater for the supply of domestic hot water, which have a thermostat-type temperature sensor, the anti-freeze function does NOT protect the water heater. It can be protected by setting the boiler to Summer or Winter , or by setting a value above 0°C on the water heater thermostat. -
Page 11: Boiler Shut-Down
1.3. Boiler shut-down If a malfunction occurs, the boiler automatically shuts down. Refer to tables 1 and 2 for boiler status. In order to determine the probable causes of the malfunction, refer to section 6 - Troubleshooting - at the end of this manual (in addition to tables 1 and 2). -
Page 12: Maintenance
