To prevent damage from freezing, the Combi Boiler must be plugged into power at all times. If power is unplugged, drain the
water completely from the Combi Boiler. Then use an air compressor to remove all water from inside the unit's water piping.
It is recommended that Isolation Valves are installed on the Combi Boiler, otherwise the water connections will need to be
removed to drain the unit completely. Freeze damage due to not draining properly will not be covered under warranty.
