Intended use
The liquid gas heater Combi is a warm-air heater with integrated hot water boiler (10 litre volume). This unit was designed for installation in motor homes (vehicle class M1) and
caravans (vehicle class O).
It must not be installed in buses (vehicle classes M2 and M3)
or in vehicles for transporting hazardous goods.

Safety instructions
What must I do if I smell gas?
– Extinguish all naked flames
– Open windows and doors
– Close all quick-acting valves and gas cylinders
– Do not smoke
– Do not operate any electrical switches
– Have the entire gas system checked by an
expert.
A safe operating environment
– The unit may be operated only with appropri-
ate Truma control panels and accessories.
– Danger of toxic exhaust fumes. The heater’s
exhaust can be toxic in enclosed spaces (e.g.
garages, workshops). If the vehicle is parked
in closed rooms:
– Shut off the fuel supply to the heater
– Deactivate the time switch
– Switch off the heater at the control panel.
– If the cowl has been placed near or directly
beneath an opening window, the appliance
must be equipped with an automatic shut-off
device in order to prevent operation with the
window open.
– Heat-sensitive objects (e.g. spray cans) or
flammable materials/ liquids must not be
stored in the same compartment where the
appliance is installed because, under certain
conditions, this area may be subject to elevated temperatures.
– Keep flammable materials away from the
area in front of the warm air outlets. Never
block the warm air outlets.
– The openings for circulated air intake, the in-
stallation compartment and the space around
the unit must be kept free of obstacles so
that the unit does not overheat.
– Keep the cowl for the exhaust duct and
combustion air intake free of contamination
(slush, ice, leaves etc.) at all times.
– Danger from hot surfaces and exhaust gas.
Do not touch the area around the wall cowl
and do not lean any objects against the wall
cowl or the vehicle.
Obligations of the operator / vehicle owner
– The operator is responsible for the water
with which the Combi boiler is filled and for
its quality.
– The vehicle owner is responsible for correct
operation of the appliance.
– The installer or vehicle owner must affix the
supplied yellow sticker with the warning
information in a location in the vehicle
where it is clearly visible to all users (e.g.
the wardrobe door). Missing stickers can be
requested from Truma.
– Liquid gas systems must comply with the
technical and administrative regulations of
the respective country of use (e.g. EN 1949
for vehicles in Europe). The national legislation and regulations (e.g. DVGW Work
Sheet G 607 for vehicles in Germany) must
be observed.
– The vehicle owner must arrange for the
gas system to be tested (in Germany every
2 years) by a liquid gas expert (DVFG, TÜV,
DEKRA). The test must be confirmed on the
respective test certificate (G 607).
– Pressure regulating devices and hoses must
be replaced with new ones no more than
10 years after their date of manufacture
( every 8 years if used commercially).
– Inspect hose lines regularly and have them
replaced if they are broken.
– If the heater is not being used, always drain
off the water if there is a risk of frost. No
claims may be made under the warranty for
damage caused by frost.
Safe operation
– The use of upright gas cylinders from which
gas is taken in the gas phase is mandatory
for the operation of gas pressure regulation
systems, gas equipment and gas systems.
Gas cylinders from which gas is taken in the
liquid phase (e. g. for fork lifts) must not be
used, since they would result in damage to
the gas system.
– The operating pressure of the gas supply
(30 mbar) and of the appliance (see type
plate) must be the same.
4
– In Germany, only pressure regulating equip-
ment that complies with DIN EN 16129 (in
vehicles) with a fixed output pressure of
30 mbar may be used for the gas system.
The flow rate of the pressure regulating
equipment must correspond to at least the
maximum consumption of all devices installed by the system manufacturer.
– We recommend the Truma MonoControl CS
gas pressure regulation system for vehicles
and the Truma DuoComfort / DuoControl CS
gas pressure regulation system for dual-cylinder gas systems.
– At temperatures of around 0 °C and below,
the gas pressure regulation system or the
changeover valve should be operated with
the EisEx regulator heater.
– Suitable hoses that meet national regulations
must always be used in the respective country
for which the equipment is destined.
– Ensure that the inside of the vehicle is suf-
ficiently ventilated. When the unit is started
up, there may be some smoke and/or smell
due to dust or dirt. Especially if it has not
been used for a long time.
– This appliance can be used by children aged
8 and over, as well as by persons with reduced physical, sensory or mental capabilities or with a lack of experience and knowledge, provided that they are supervised or
have been instructed on how to use the appliance safely and that they understand the
resulting risks. Children must not be allowed
to play with the appliance.
– The integrity and tight fit of the exhaust
double duct must be checked regularly,
particularly at the end of long trips. Also
check the mounting of the unit and the cowl.
Operation while driving
– Directive UN ECE R 122 stipulates that a
safety shut-off device is required if motor
homes and caravans are heated while driving. The Truma MonoControl CS gas pressure regulation system satisfies this requirement. Throughout Europe, a type-tested
liquefied gas heating system may be used
while driving (according to the directive
UN ECE R 122) if the system includes a gas
pressure regulator with an appropriately configured gas installation. National regulations
and rules must be followed.
– If no safety shut-off device (e.g. as contained
within the Truma MonoControl CS gas pressure regulation system) has been installed,
the gas cylinder must be closed when driving and information signs must be attached in the gas cylinder protection box and
in the vicinity of the control panel.
– Liquid gas equipment must not be used
when refuelling, in multi-storey car parks, in
garages or on ferries.
– To prevent damage to the appliance from
spray water, such as when cleaning the
vehicle, do not spray water directly into the
cowl.
Troubleshooting
– If you notice unusual noises or smells, close
off the gas supply and switch off the Combi.
– Danger of fire / explosion if you attempt to
use a Combi that has been damaged by
flooding or if the vehicle has been involved
in an accident. A damaged Combi must be
repaired by an expert or be replaced.
– Have faults repaired by an expert without
delay.
– Only carry out repairs yourself if the solution
is described in the troubleshooting guide of
this manual.
– Following a deflagration (backfire), have the
appliance and the exhaust duct checked by
an expert.
