1.1.14. ANTI-FREEZE PROTECTION
The boiler is protected against freezing using the
electronic board design with a function that start
the burner and heat the water in the boiler when
their water temperature goes below the minimum
pre-set values, protecting the boiler up to an
external temperature of 14 °F (-10 °C).
The device starts when the hot water temperature
goes below 41 °F (5 °C), automatically starting the
burner until the water reaches the temperature of
86 °F (30 °C).
The system starts even if display appears “OFF”,
as long as the boiler is connected to the power (120
V) and gas supply.
For long periods of standby, please empty the
boiler and the plant.
If the temperature goes below 14 °F (-10 °C)
centigrades, please fill the plant with anti-freeze
liquid (CLEANPASS FLUIDO AG cod. 98716LA)
and insert and electrical resistances kit (cod.
82259LP).
