The unit is equipped with a frost protection system that activates the boiler in hea-
ting mode when the system delivery 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,
for system protection use a suitable antifreeze liquid that meets the same require-
ments as set out above and provided for by Standard UNI 8065.
In the presence of adequate chemical/physical system and feed water treatments
and related high cyclicity controls able to ensure the required parameters, for in-
dustrial process applications the product can be installed in open-vessel systems
with vessel hydrostatic height able to ensure compliance with the minimum opera-
ting pressure indicated in the product technical specifications.
The presence of deposits on the boiler exchange surfaces due to non-com-
pliance with the above requirements will involve non-recognition of the
warranty.
Frost protection kit for outdoor installation (optional)
In case of installation outdoors in a partially protected place, for temperatures below -5°C and down to -15°C, the boiler
must be fitted with the special frost protection kit. For proper installation, please refer to the instructions in the kit.
