Preventing Damage from Freezing-2
If the Combi Boiler will not be used for a long period of time, drain the water.
CAUTION
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.
Drain the water as follows:
* Drain water into a bucket to prevent water damage.
