- switch the boiler on and ensure correct ignition;
- make sure that the gas flow rate and relevant pressure values
comply with those given in the manual (Par. 4.2);
- ensure that the safety device is engaged in the event of gas supply
failure and check activation time;
- Check the intervention of the main switch located upstream from

1.34 KITS AVAILABLE ON REQUEST.
• System shut-off valves kit. The indoor unit is designed for in-
stallation of system interception cocks to be placed on flow and
return pipes of the connection assembly. This kit is particularly
useful for maintenance as it allows the indoor unit to be drained
separately without having to empty the entire system.
• Polyphosphate dispenser kit (only for indoor installation). The
polyphosphate dispenser reduces the formation of lime-scale
and preserves the original heat exchange and domestic hot water
production conditions. The indoor unit is prepared for applica-
tion of the polyphosphate dispenser kit.
• Cover Kit. If installed outdoors in a partially protected place with
direct air intake, it is compulsory to mount the appropriate top
protective cover for the correct functioning of the indoor unit
and to protect it from adverse weather conditions.
• Cycloidal filter kit (on request). The magnetic cycloidal filter is
able to detect the ferrous residues present in the system's water.
Thanks to the two cocks in the kit, it facilitates maintenance by
cleaning the filter without having to empty the circuit.
The above-mentioned kits are supplied complete with instructions
for assembly and use.
