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.
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.
Air intake and flue gas venting system Flue gas discharge into the atmosphere and air intake/flue gas venting systems must comply with applicable laws and standards in the country of installation that are considered as fully transcribed herein. When positioning the boiler exhaust terminals onto the wall, comply with the distances specified in the applicable standards and regulations in force in the Country of installation, which are herein considered as entirely transcribed.

3.6.1 Possible configuration of air intake and flue gas venting ducts Type B22 • Boiler intended for connection to a chimney pipe or a device for flue gas venting external to the boiler room. • Combustion air is taken directly from the boiler room itself while flue gas is conveyed to the outside.
Page 26
Type C52 • Boiler with separate pipes for combustion air intake and flue gas evacuation. • These flues may discharge in areas at a different pressure. • The terminals may not face each other from opposed walls. Type C62 • Boiler designed to be sold without air intake or flue gas venting ducts.
Page 27
3.6.2 Air intake and flue gas venting via 100/60 mm coaxial pipes Type C12 • Maximum permissible length of horizontal coaxial pipes is 3 metres. • For each additional 90° elbow, maximum permissible length is to be reduced by 1 meter. •...
Page 28
Type C32 • Minimum permissible length for vertical coaxial pipes is 1 metre, equal to the length of the chimney. • Maximum permissible length for vertical coaxial pipes is 10 metres, including the chimney. • For each additional 90° elbow, maximum permissible length is to be reduced by 3 meters. •...

Checking combustion efficiency 3.7.1 Flue cleaning function • The boiler features a flue cleaning function which must be used to measure combustion efficiency during operation and to adjust the burner. • To activate the flue cleaning function, press and hold the buttons “Info” and “Reset” simultaneously for 5 seconds. The flow temperature and symbol are shown on the LCD.
Connection to gas mains DANGER Before connecting the boiler to the gas mains, make sure that the gas type and the supply conditions correspond to the specifications on the boiler technical data plate. If this is not the case, do not connect the boiler to the gas mains. Cross-section gas pipe size must be chosen depending on its length, layout pattern, gas flow rate.
Hydraulic connections 3.9.1 Central heating Prior to installing the boiler, the hydraulic system is to be cleaned in order to remove impurities; they could be present in system components and damage the pump and the heat exchanger. The CH outlet and return pipes must be connected to the respective 3/4” connectors M and R on the boiler (see Fig. 5 Paper template). When calculating the cross section of CH system pipes, bear in mind load losses induced by radiators, thermostatic valves, radiator gate valves, and the configuration of the system itself.
3.12 Installation and operation with Open Therm Remote Control (optional) WARNING Only use original Remote Control Units supplied by the manufacturer. The correct operation of the Remote Control itself and of the boiler is not guaranteed if non original Remote Control units not supplied by the manufacturer are used.
