Function description
The liquid gas heater Combi E is a warm-air
heater with integrated hot water boiler (10 liter
volume). The burner operates fan-supported,
which ensures trouble-free function even
when on the move. The unit also has heating
elements for electrical operation.
In winter operation the heater can be used to
heat the room and simultaneously warm water.
If only warm water is required, select summer
operation.
3 different options are available for operating
the unit.
• gas operation only Propane / Butane for
autonomous use
• electrical operation only 230 V for stationary
use on camp sites
• operation only possible in winter mode.
Winter operation
In winter operation, the unit automatically
selects the required power setting according
to the temperature difference between the
temperature set on the control panel and the
current room temperature. When the boiler
is filled, the water is automatically heated as
well. The water temperature depends on the
selected operational mode and the heater
output.
All 3 energy selection options can be used for
winter deployment.
With gas operation the unit automatically
selects the output level that is required.
Depending on the fuse protection at the
camping site, power of 900 W (3.9 A) or 1800
W (7.8 A) can be manually selected for electrical
operation.
