1.1.14. ANTI-FREEZE PROTECTION
The water heater 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 water
heater 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
59 °F (15 °C).
The system starts even if display appears “OFF”,
as long as the water heater is connected to the
power (120 V) and gas supply.
For long periods of standby, please empty the
water heater and the plant.
If the temperature goes below 14 °F (-10
°C) centigrades, please insert the electrical
resistances kit (cod. 82259LP).
