The unit is equipped with a frost protection system that activates the boiler in heating mode
when the system flow water temperature falls below 6°C. The device is not active if the
power and/or gas supply to the unit is turned off. If necessary, to protect the system use a
suitable antifreeze liquid that meets the above requirements and provided for by UNI 8065.
In the presence of adequate chemical/physical system and feed water treatments and re-
lated high cyclicity controls able to ensure the required parameters, for industrial process
applications the product can be installed in open-vessel systems with vessel hydrostatic
height able to ensure compliance with the minimum operating pressure indicated in the
product technical specifications.
The presence of deposits on the boiler exchange surfaces due to non-compliance
with the above requirements will involve non-recognition of the warranty.
