3.2.4. Installing the boiler
Prior to connecting the boiler to the hot water for domestic use and heating system pipes make sure to thor-
oughly clean the system.
- Before commissioning a NEW system, clean it to remove any machining and welding metal residues, oil and
fat that could damage the boiler if they reach it.
- Before commissioning a system that has been subjected to overhaul (adding radiators, replacing the boiler
etc.), clean it to remove any sludge and foreign particles.
For this purpose use appropriate products available on the market and make sure they do not contain acids.
Do not use solvents that may damage the components.
Furthermore, in each heating system (new or overhauled) add to the water suitable corrosion inhibitors, in due
concentration, for systems made from multiple metals so as to form a protection layer on the inner metallic
surfaces.
The manufacturer declines any liability for damages caused to persons, animals or objects arising from failure
to comply with the indications above.
For all system types fit to the boiler inlet, on the return line, an easy-to-open filter (Y-shaped type) with Ø 0.4
mm mesh.
3.2.4.1. Direct installation on the wall using the bracket kit (bracket A)
Follow the indications below to install the boiler:
- fasten the template (fig. 5) to the wall;
- drill the holes in the wall for the retaining blocks of the boiler support bracket (bracket A in fig. 5);
- drill, if necessary, the holes for the passage of the air suction / fumes exhaust pipes;
- fasten to the wall using the two expansion hook anchor bolts;
- position the fittings for the connection of the gas supply pipe (G), the cold water supply line (F), the hot water outlet (C, for Play Entry
version only), the secondary supply toward the boiler (for Play Entry SV version only), the secondary return from the boiler (for Play Entry
SV version only), the heating delivery line (M) and the heating return line (R) by matching them to the same points on the template (bottom
side);
- prearrange connection for condensate draining and a 3-bar safety valve draining, too;
- hang the boiler to the hooks of the blocks;
- connect the boiler to the supply pipe (refer to paragraph 3.2.9);
- connect the boiler to the condensate draining system (refer to paragraph headed 3.2.9);
- connect the boiler to the 3-bar safety valve draining system;
- connect the boiler to the air suction / fumes exhaust system (refer to the paragraph 3.2.6 and related sub-paragraphs);
- connect the power supply, the room thermostat (if provided) and any other accessories (see the following paragraphs).
3.2.4.2. Wall-mounting using the option metal bracket (B)
Follow the indications below to install the boiler:
- fasten the template (fig. 5) to the wall;
- drill the holes in the wall for the retaining blocks of the boiler support bracket (bracket B (008445013) in fig. 5);
- drill, if necessary, the holes for the passage of the air suction / fumes exhaust pipes;
- fix the bracket B to wall using the expansion bolts;
- remove and fit back on the boiler the standard bracket (A) reversed;
- position the fittings for the connection of the gas supply pipe (G), the cold water supply line (F), the hot water outlet (C, for Play Entry
version only), the secondary supply toward the boiler (for Play Entry SV version only), the secondary return from the boiler (for Play Entry
SV version only), the heating delivery line (M) and the heating return line (R) by matching them to the same points on the template (bottom
side);
- prearrange connection for condensate draining and a 3-bar safety valve draining, too;
- hang the boiler to the bracket B previously fastened to the wall;
- connect the boiler to the supply pipe (refer to paragraph 3.2.9);
- connect the boiler to the condensate draining system (refer to paragraph headed 3.2.9);
- connect the boiler to the 3-bar safety valve draining system;
- connect the boiler to the air suction / fumes exhaust system (refer to the paragraph 3.2.6 and related sub-paragraphs);
- connect the power supply, the room thermostat (if provided) and any other accessories (see the following paragraphs).
