Function description

The liquid gas heater Combi E is a warm-air heater with inte-
grated 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. The unit is unsuitable for use as an instantaneous
water heater.
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.
At a temperature of approximately 3° C at the automatic
FrostControl safety/drain valve, the valve will open and drain
the boiler.
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
– or gas and electrical operation – mixed 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 tempera-
ture 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.
If more output is required (e.g. heating up or low outside
temperatures) gas or mixed operation should be selected so
that enough heating power is always available.
With mixed operation, 230 V electrical operation is preferred
if the power requirement is low (e.g. for maintaining the room
temperature). The gas burner is not enabled until the power
requirement is higher, and is the first to switch off during
heat-up operations.
Summer operation
(boiler operation only)
Gas operation or 230 V electrical operation is used for hot
water preparation. The water temperature can be set to 40° C
or 60° C.
With gas operation the water is heated at the lowest burner
setting. Once the water temperature is reached, the burner
switches off.
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.
Mixed operation is not possible. With this setting the
unit automatically selects electrical operation. The gas
burner is not enabled.
