Frost protection is fitted as standard on all models manufactured from 2010
onwards. Frost protection operates automatically (as required) whenever the
appliance is connected to the electric power supply.
If you live in an area prone to frost and will be away for an extended period with the power
supply disconnected, Rinnai recommend draining your appliance to prevent frost damage
(not covered by warranty).
We strongly recommend having your water heater drained b
y a plumber or gas fitter but
understand that remote locations and cost may prohibit this.
