2 - APPROPRIATE USE OF APPLIANCE
The FIREX
appliance 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 intended to operate in hot air circulation heating systems. Any other use must be considered
improper.
Firex shall not be held liable for any damage resulting from improper use; in this case the user is fully
responsible for the risk.
Use according to the intended purposes also includes careful compliance with the instructions in this manual.
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.
