Bottled gas operation
When heating using bottled gas, the bottled gas valve
must be open.
Heating using the immersion heater requires a 230 V
supply.
Electrical operation
The boiler’s immersion heater is connected to the 230 V
circuit and separately protected by a 16 A circuit breaker.
The boiler’s immersion heater has three power modes.
Higher power means faster heating, but requires more
current . Thus, it must be ensured that the connected
power cable can handle this (otherwise, the circuit breaker
will trip).
Power mode: 1 kW
Required fuse: 6 A
2 kW 10 A
3 kW 16 A
The boiler takes its combustion air via a suction pipe and
releases the exhaust via the chimney on the roof. Com-
bustion is thus entirely screened from the motorhome’s
interior.
The boiler has a flame failure safety device that automa -
tically cuts off the gas supply if, for any reason, the flame
goes out.
Descriptions – Heating system
The boiler’s bottled gas mode turns off when the engine is
started.
Certain motorhomes (certain models) have a crash sensor
in the bottled gas system. This enables bottled gas opera-
tion while travelling. The boiler’s bottled gas mode conti -
nues when the engine is started.
The crash sensor prevents gas leaks in the event of col
-
lision or similar.
The boiler’s bottled gas mode always turns off when the
motorhome’s engine is turned off. Bottled gas operation
restarts after around 15 minutes.
