fILLInG THE WATER HEATER
1. Close electrical safety/drain valve at the
control knob by lifting up (position m).
At temperatures of around 8°C and less,
switch on the heater or water heater first,
to make sure the valve does not open
again!
2. Switch on power for water pump (main
switch or pump switch).
3. Open hot water taps in kitchen and
bathroom, (set preselecting mixing taps
or single-lever fittings to ‘hot’). Leave taps
open until the water heater has forced out
air and filled up with water and water is
flowing out of the taps.
If just the cold water system is being operated,
without using the water heater, the heater
tank also fills up with water. In order to avoid
damage by frost, the water contents must be
drained by operating the safety/drain valve,
also when the water heater has not been used.
As an alternative, two shutoff valves, resistant
to hot water, can be fitted in front of the cold
and hot water connection.
When connecting to a central water
supply (rural or city mains), a pressure
reduction valve must always be installed
to prevent pressures above 2.8 bar from
developing in the water heater.
DRAInInG THE WATER HEATER
1. Interrupt power for water pump (main
switch or pump switch).
2. Open hot water taps in kitchen
and bathroom.
3. Open electrical safety/ drain valve at
control knob by pressing in (position n).
The water heater content is now emptied
to the outside through the safety/drain
valve. Place a bucket beneath the outlet
to check whether the water content has
completely drained away (12 litres). There
shall be no claims under guarantee for
damage caused by frost!
GAS oPERATIon (HEATInG AnD

a = Rotary switch for room temperature (1 – 9)
b = Green ‘Operation’ monitor lamp
c = Summer operation (water temperature
40°C or 60°C)
d = Winter operation (heating without water
temperature monitoring or with drained
water system)
e = Winter operation (heating with water
temperature monitoring)
f = Rotary ‘Off’ switch
g = Yellow ‘Boiler heating phase’ monitor lamp
h = Red ‘Fault’ monitor lamp
When using vehicle-specific switches: refer to
operating instructions of vehicle manufacturer.
RooM THERMoSTAT
i = Room temperature sensor
To measure the room temperature, an
external room temperature sensor (i) is located
in the vehicle. The location of the sensor
is determined individually by the vehicle
manufacturer, depending on the vehicle type;
consult the operating instructions for your
vehicle for further details.
The thermostat setting on the control panel
(1 – 9) must be determined individually
depending on the heating requirement and
the type of vehicle. For an average room
temperature of about 23°C, we recommend a
thermostat setting of about 6 – 8.
TAKInG InTo oPERATIon
1. Check that the cowl is not obstructed.
Always remove any covers, open deck cowl
on boats.
In winter, if a roof cowl is fitted, it is
recommended that a cowl extension be
fitted (see Accessories). This must be
removed when the vehicle is on the move.
To run the cowl through the roof on a
caravan, a cowl extension piece is likewise
used, which must be fixed to the roof with
clamp rings (see Accessories).
2. Turn on gas cylinder and open quick-acting
valve in the gas supply line.
Heating operation is basically possible
without restriction with or without
water content.
SUMMER oPERATIon (HoT WATER onLY)
Set the rotary switch to Summer operation (c),
40°C or 60°C.
Once the water temperature which has been
set (40°C or 60°C) has been reached, the
burner will switch off and the yellow monitor
lamp (g) will go out.
WInTER oPERATIon (HEATInG WITH
WATER TEMPERATURE MonIToRInG)
1. Set the rotary switch to the operational
setting ‘e’.
2. Set the rotary switch (a) to the desired
thermostat setting (1 – 9). The green
indicator lamp (b) illuminates and indicates
the room temperature setting.
The device automatically selects the setting
that is required in accordance with the
difference between the temperature setting
and the current room temperature.
Once the room temperature set on the control
panel has been reached, the burner switches
back to the lowest stage, and heats the water
content to 60°C. The yellow monitor lamp (g)
indicates the heating-up phase is in progress,
and goes out once the appropriate water
temperature has been reached.
HEATInG WITHoUT WATER
TEMPERATURE MonIToRInG
1. Set the rotary switch to the operational
setting ‘d’.
2. Turn the rotary switch (a) to the desired
thermostat setting (1 – 9). The green
indicator lamp (b) illuminates and indicates
the room temperature setting.
The device automatically selects the setting
that is required in accordance with the
difference between the temperature setting
and the current room temperature. Once the
room temperature set on the control panel has
been reached, the heating will switch off.
If the boiler is filled, the water will
automatically be heated at the same time.
The water temperature is then dependent
on the heating output being given off, and
the duration of heating required to reach the
desired room temperature.
In this operational mode, the yellow monitor
lamp (g – boiler heat-up phase) only lights up if
the water temperature is below 5°C!
Heating operation is basically possible
without restriction with or without
water content.
HEATInG WITH DRAInED WATER SYSTEM
1. Set the rotary switch to the operational
setting ‘d’.
2. Turn the rotary switch (a) to the desired
thermostat setting (1 – 9). The green
indicator lamp (b) illuminates and indicates
the room temperature setting.
The device automatically selects the setting
that is required in accordance with the
difference between the temperature setting
and the current room temperature.
