    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 consi- dered 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.

  • Page 37: Positioning The Boiler

    Positioning the boiler Each boiler is supplied with a paper template, found inside the packaging (see Fig. 9 Paper template). The template allows you to ensure that the pipes connected to the CH 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 38: 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. Before commissioning a RECONDITIONED system (where radiators have been added, the boiler has been replaced, etc.) thoroughly clean it to remove any sludge and residues.

  • Page 39: Fig. 10 Fastening The Trap

    In order to install the boiler proceed as follows: • Affix the template to the wall. • Drill two Ø 14 mm holes in the wall to accommodate the boiler bracket wall blocks. • If necessary, provide holes in the wall to allow air intake and/or flue gas venting ducts to pass through it; •...

  • Page 40: Boiler Room Ventilation

    Boiler room ventilation The boiler has sealed combustion chamber. Combustion air is not drawn from boiler room, therefore no specific recommendations need to be applied concerning the boiler room or openings and ventilation provided to the boiler room. In the case of type B23 installation in a closed room, air vents must be provided for in compliance with the standards in force in the country of installation.

  • Page 41: Fig. 11 Split Kit Installation

    3.6.1 Starter kit installation Refer to Fig. 11 Split kit installation and to Fig. 12 Coaxial kit installation. DANGER There must be no leakage of combustion by-products from any of the gaskets. Split kit (optional) Clean the boiler roof from dust and other debris due to any masonry works. Fix the adhesive gasket under the flange connection for flue gas venting system (A).

  • Page 42: Fig. 13 Installation Examples

    3.6.2 Pipe and terminal installation DANGER Flue gas venting pipes are to be installed tilted toward the boiler so that condensate runs toward the combustion cham- ber, which is designed for condensate collection and drainage. Should the above procedure not be possible, it is necessary to install, in condensate stagnation areas, devices designed for condensate collection and conveying to the condensate drain system.

  • Page 43: Fig. 15 Wall-Mounted Terminal Installation

    Wall-mounted terminals The final parts of air intake and flue gas venting terminals, both split and coaxial, feature a groove (A) to fix the external collar (see Fig. 15 Wall-mounted terminal installation). Insert the external collar into the terminal until reaching the groove. Insert the terminal, from outside, making the external collar adhere to the wall.
