Page 23: Instructions For The Installer
3. Instructions for the installer Installation standards This boiler must be installed in compliance with the laws and standards in force in the country of installation, which are herein considered as entirely transcribed. To find out about the gas category and technical specifications, refer to operation data and general features specified in the previous pages. DANGER Accessories and spare parts for installation and service procedures are to be supplied by the Manufacturer. -
Page 24: Positioning The Boiler
Positioning the boiler Each boiler is supplied with a paper template, found inside the packaging (see Fig. 5 Paper template). The template allows you to ensure that the pipes connected to the CH system, the DHW system and the gas mains, and the air intake/flue gas venting ducts are all laid out correctly during the realisation of the water system and before installation of the boiler. -
Page 25: Installing The Boiler
Installing the boiler DANGER Before connecting the boiler to CH and DHW networks, clean the pipes carefully. Before commissioning a NEW system, clean it to remove any metal chips due to machining and welding, and any oil and grease that might negatively affect boiler operation or even damage it in case they get inside it. - Page 26 DANGER The boiler is equipped with a safety device for flue gas exhaustion check. It is strictly forbidden to tamper with and/or prevent operation of such safety device. Should an air/flue gas system malfunction occur, the device will shut-down the boiler by interrupting the gas supply to the boiler and the LCD will display the E03 code.

Page 34: Fig. 9 Thermoregulation Curves
The figure shows the curves for a fictitious ambient temperature of 20°C.Parameter P10 allows selecting the curve value shown (see Fig. 9 Thermoregulation curves). If fictitious ambient temperature value is edited on boiler display, the curves shift up or down, respectively, by the same amount. With a fictitious ambient temperature setting of 20°C, for example, if you select the curve corresponding to parameter 1 and the outdoor temperature is - 4°C, the CH flow temperature will be 50°C. -
