Safety
Always wear the proper protective clothing and shoes when
servicing the water heater. Wearing jewelry and loose clothing
can contribute to unsafe situations.
In order to keep the R18 in a safe working condition, the water
heater should be inspected and serviced at least once every
year and cleaned if necessary.
Frost protection
When water heater is not in operation for a long period of time,
the heat exchanger should be protected against frost. This can
be achieved by draining water from the heat exchanger.
Inspecting the draught diverter
The draught diverter and heat exchanger can be inspected and
cleaned with the minimum on tools and time. Place yourself in
the draught diverter and execute the following:
