technical safety rules.

 

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

The appliance is intended to operate in hot air circulation heating systems. Any other use must be considered

3 -  WATER TREATMENT

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

•  We recommend checking and cleaning any installed domestic hot water exchanger at the end of the fi rst 

year of use and every two years thereafter; on this occasion, also check the state of wear of the anode.
