The KON boiler has been built according to the current level of engineering and acknowledged 

technical safety rules. 

Nonetheless, if improperly used, dangers could arise for the safety and life of the user and 

other persons or damage to the equipment or other objects. 

The appliance is designed to work in heating systems, with hot water circulation, for the pro

-

duction of domestic hot water.

Any other use is considered improper. 

UNICAL AG S.p.A. will not be held liable for any damage resulting from improper use.

Use according to the intended purposes also includes strict compliance with the instructions 

in this manual.

The user must be instructed concerning the use and operation of the heating system, in particular: 

•  Deliver these instructions to the user, as well as other documents concerning the appliance 

inserted in the envelope inside the packaging. The user must keep this documentation safe 

for future consultation. 

•  Inform the user about the importance of the air vents and the flue gas exhaust system, high

-

lighting their essential features and the absolute prohibition of modifying them. 

•  Inform the user concerning controlling the system's water pressure as well as operations to 

restore it. 

•  Inform the user concerning correct temperature control, control units/thermostats and radiators 

for saving energy.

•  Remember that the system must receive regular maintenance at least once a year and com

-

bustion analysis must be performed every two years (as per national law).

•  Should the appliance be sold or transferred to a new owner or if you move and leave the

  BY THE INSTALLATION/MAINTENANCE TECHNICIAN

3 - WATER TREATMENT

•  The hardness of the feed water conditions the frequency at which the domestic hot water 

exchanger must be cleaned.

•  If the water has a hardness greater than 15°f, we recommend using water softeners, chosen 

according to the characteristics of the water.

•  In order to improve scaling resistance, it is recommended to adjust the domestic hot water at 

a temperature very close to that actually used.

•  It is recommended to verify the cleanliness of the domestic hot water exchanger at the end 

of the first year, and then according to the level of scaling found; the period can be extended 

to two years.

Pay special attention when reading this manual to the parts marked by the symbols:  

Provisions for proper disposal of the product in accordance with Directive 2002/96/EC 

At the end of its life cycle the product must not be disposed of as urban waste. It can be taken to 

a special recycling centre managed by the local authorities, or to a dealer who offers this service.  

Separate disposal of a domestic appliance avoids possible negative consequences for the environment 

and human health deriving from inappropriate waste handling and allows the recovery of the materials 

of which it is made, in order to obtain significant energy and resource savings.
