different operating modes, e.g., summer operation or winter
operation.

Prior to operating any equipment, reading the detailed safety
and operating instructions contained in the operating manual
of the relevant manufacturer is mandatory!
If a malfunction occurs, always check the gas bottle valve and
the quick-action valve first, ensuring that both are open. The
safety relief valve must be closed and the water level must be
sufficient.
If the flaw cannot be repaired, contact the nearest specialist a
workshop!
