Instructions for the installer
3.8.2
DHW
Cold water inlet and DHW outlet shall be connected to the boiler through the dedicated fittings (see
Hydraulic connections
on page
55
).
WARNING
Depending on the hardness of the mains water supply, ascertain whether or not to install appropriate domestic water treatment
systems using water treatment products suitable for drinking water and compliant with the regulations and standards in force in
the country of installation.
Water treatment is always advisable when water supplied to the boiler is more than 20°F hard.
Water supplied by commonly marketed water softeners, due to PH level induced in water, may not be compatible with some
components in the system.
3.8.3
Solar collectors
Connection to solar collectors is made by connecting the solar flow pipe (from collectors to boiler) and solar return pipe (from boiler to
collectors) to the relevant fittings as shown in the figures in par.

3.8.4
Condensate drain
Comply with condensate drain laws and standards applicable in the country of installation, which are considered herein integrally transcribed.
Unless forbidden, the condensate produced by combustion is to be routed via the condensate drain through a discharge system connected
to the domestic sewer, which due to its basicity, counteracts flue gas condensate acidity. In order to avoid domestic sewer odour to reach the
premises, it is advisable to install an appropriate device between the discharge system and the domestic sewer. The condensate drain system
and the domestic discharge system is to be made of an adequate, condensate-resistant material.
WARNING
The manufacturer shall not be held responsible in case of damage to people, animals, or property due to failure to follow the above
mentioned instructions.
