NOTE
• Switch off the heating system's main switch when
the vehicle is not used.

chimney and the inlet and discharge valves are
kept free of snow and ice.
• You can heat the heating system without having
filled the hot water boiler with fresh water.
• You can operate the gas boiler and the electric
heater at the same time.
• Always drain the fresh water from the hot water
boiler when there is a risk of freezing and the
vehicle is not used.
• The liquefied gas heater must not be in operation
when you refuel the vehicle within a garage or
similar environment.

without glycol solution.
