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 the heater off on the control panel.
– Make sure that units definitely cannot be
switched on via the Truma App.
– If the cowl has been placed near or directly
beneath an opening window, the device
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
installation 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 infeed 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 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.
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.
– 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.
– For vehicles, we recommend the
Truma MonoControl CS gas pressure regulation system and the Truma DuoComfort /
DuoControl CS gas pressure regulation system for two-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 may be used by children from
8 years old and by persons with disabilities
or with a lack of experience if they are supervised or have been instructed in the safe use
of the appliance and 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 liquid gas
heater may be used while driving (according
to the directive UN ECE R 122) if the system
includes a gas pressure regulation system
with an appropriately configured gas instal
lation. 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
appliance.
– Danger of fire / explosion if you attempt to
use an appliance that has been damaged by
flooding or if the vehicle has been involved in
an accident. A damaged appliance 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 operating instructions.
– Following a deflagration (backfire), have the
appliance and the exhaust duct checked by
an expert.
Maintenance / Repairs / Cleaning
– The unit may only be repaired and cleaned
by an expert.
– Maintenance, repairs and cleaning must not
be done by children.
– Guarantee claims, warranty claims and ac-
ceptance of liability will be ruled out in the
event of the following:
– Modifications to the device (including
accessories),
– Modifications to the exhaust duct and the
cowl,
– Use of replacement and accessory parts
other than original Truma parts,
– Failure to follow the installation and
operating instructions.
The device’s operating permit, and consequently also the vehicle’s operating permit in
some countries, are also rendered void.

Function description
VarioHeat is s warm air heater for air circulation to heat camping vehicles quickly. The burner is fan-assisted, which ensures
that operation is problem-free, even when on the move.
The unit automatically selects the required operating level according to the temperature difference between the setting on
the control panel and the current room temperature.
A boost function for quick heating and a night function for
low-noise operation are also available. The various fan settings allow air circulation mode without heating.
The digital control panel can be used to select other functions such as time switch or operation of a Truma air conditioning system. Information on this can be found under
TrumaCPplus VarioHeat digital control panel
This unit always starts up at the lowest setting. If this is not
sufficient to achieve the desired temperature inside the vehicle, the unit switches to a higher operating level within a
few minutes.
Operating instructions
Always observe the operating instructions and the “Important operating notes” prior to starting! The vehicle
owner is responsible for correct operation of the appliance.
The installer or vehicle owner must affix the yellow sticker
with the warning information, which is enclosed with the appliance, 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.
