DOMESTIC HOT WATER (only for KC model)
DHW flow and water mains inlet pipes are to be connected to the relevant 1/”
CWI
and
DHW
couplings on the boiler (pic. 5).
Hardness of water supplied to the boiler may increase the plate heat exchanger cleaning/replacement frequency.
All DHW circuits, connections, fittings, etc. should be fully in accordance with relevant standards and water supply regulations.
Depending on hardness level of the water supplied, it might be necessary installing a suitable water treatment device
for domestic use and in compliance with applicable laws and standards.
Water treatment is always advisable when water supplied to the boiler is more than 20°F hard.
Water treated by commonly marketed water softeners, due to PH level induced in water, may not be compatible with
some components in system.
CONDENSATE DRAIN
Comply with condensate drain laws and standards applicable in the country of installation and which are considered herein integrally
transcribed.
When the law is not stating differently, the condensate produced by combustion, is to be routed (via the condensate drain S in pic. 5)
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 adequate condensate resistant material.
Manufacturer shall not be held responsible for any damage to people, animals or objects, resulting as failure in observing the above
mentioned technical precaution.
