What must I do if I smell gas?
– Avoid ignition sources, e.g. extinguish all
naked flames, do not actuate any electrical
switches or use any mobile phones or radios
in the vehicle, do not start the vehicle’s en-
gine, do not operate any appliances, do not
smoke.
– Open windows and doors
– Evacuate all persons from the vehicle.
– Shut off gas cylinders and/or shut off the gas
supply from the outside.
– Have the entire gas system inspected and
repaired by qualified experts.
– Do not put the gas system back into opera-
tion until after it has been inspected and
repaired.
A safe operating environment
The appliance may be operated only
with appropriate 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 vehi-
cle 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 the appliances definitely
cannot be switched on via the Truma App.
Danger of fire / explosion during refuel-
ling. The appliance must not be operated
during refuelling:
– the vehicle,
– the caravan’s towing vehicle or
– other appliances.
Switch off the LP gas appliance at the control
panel. Shut off the gas supply to the LP gas
appliance. Make sure that the LP gas appli-
ance can definitely not be switched on under
any circumstances.
If the cowl has been placed near or di-
rectly beneath a window that can be
opened, the appliance must be equipped with
an automatic shut-off device in order to pre-
vent operation with the window open.
Never use objects (e.g. spray cans, can-
dles) or flammable materials, liquids,
gaseous substances or vapours in the vicinity
of the appliance, in the installation compart-
ment or in the appliance itself.
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 appliance must be kept free
of obstacles so that the appliance does not
overheat.
Keep the cowl for the exhaust duct and
combustion air infeed free of contamina-
tion (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.

4
Obligations of the operator / vehicle owner
The vehicle owner is responsible for cor-
rect operation of the appliance.
The installer or vehicle owner must affix
the yellow warning information sticker
that is provided with the appliance to the ve-
hicle in a location that is clearly visible to all
users. Missing stickers can be requested from
Truma.
The appliance, the gas system and the
exhaust duct for the combustion prod-
ucts must be inspected by a recognised expert
in accordance with the national regulations
(e.g. DVGW Worksheet G 607 in Germany) or,
if there are no such regulations, at least every
two years.
– A recognised specialist must carry out a leak
test after changes have been made to the
liquid gas system.
– The vehicle owner is responsible for having
the check carried out.
Pressure regulating devices and hoses
must be replaced with new ones no
more than 10 years after their date of manu-
facture (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 tak-
en in the liquid phase (e. g. for fork lifts) must
not be used, since they would result in dam-
age 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 appliances installed by the
system manufacturer.
For vehicles, we recommend the Truma
MonoControl CS gas pressure regula-
tion system and the Truma DuoComfort /
DuoControl CS gas pressure regulation sys-
tem for two-cylinder gas systems.
At temperatures of around 0 °C and be-
low, the gas pressure regulation system
or the changeover valve should be operated
with the EisEx regulator heater.
Suitable hoses that meet national regula-
tions must always be used in the respec-
tive destination country.
During the initial start-up of a brand new
appliance, small quantities of fumes and
a slight odour may briefly occur. When the ap-
pliance is started up after a particularly long
period of non-use, there may be some smoke
and/or smell due to dust or dirt. It is a good
idea to allow the appliance to run at maximum
output for a few minutes for the purpose of
self-cleaning and to ensure that the area is
well ventilated.
This appliance may be used by children
from 8 years old and by persons with
reduced physical, sensory or mental capabili-
ties or with a lack of experience only 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 appliance and the cowl.
To prevent damage to the appliance
from spray water, such as when cleaning
the vehicle, do not spray water directly into
the cowl.

5
Operation while driving
For heating while driving, the UN ECE regula-
tion 122 stipulates a safety shut-off device to
prevent the uncontrolled escape of gas in the
event of an accident. The Truma MonoControl
CS gas pressure regulation system fulfils this
requirement. National regulations and rules
must be followed.
If no safety shut-off device (e.g. no
MonoControl CS) is installed, the gas cylin-
der must be closed while driving and notices
must be attached in accordance with the
valid regulations.
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 dam-
aged 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 with-
out delay.
Only carry out repairs yourself if the so-
lution is described in the troubleshooting
guide of this operating instructions.
Following a deflagration (backfire), have
the appliance and the exhaust gas sys-
tem checked by an expert.
Maintenance / Repairs / Cleaning
The appliance may only be maintained,
repaired and cleaned by an expert.
Maintenance, repairs and cleaning must
not be done by children.
It is prohibited to use products contain-
ing chlorine on and inside the appliance.

6
Read the safety instructions and operating instructions
carefully before starting the appliance. 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 ap-
pliance, in a location in the vehicle where it is clearly visible to
all users. Missing stickers can be requested from Truma.
Function description
VarioHeat is a warm air heater for air circulation to heat camp-
ing vehicles quickly. The burner is fan-assisted, which ensures
that operation is problem-free, even when on the move.
The appliance automatically selects the required operating
level according to the temperature difference between the set-
ting 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 set-
tings 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 Truma CP plus
VarioHeat digital control panel
This appliance always starts up at the lowest setting. If this is
not sufficient to achieve the desired temperature inside the
vehicle, the appliance switches to a higher operating level af-
ter about 5 minutes.
Start-up
– Remove the cowl cover.
– Open the gas cylinder and the quick-acting valve in the gas
supply line.
– Switch on the heater, see.
Truma CP plus VarioHeat digital control panel or
Truma CP classic VarioHeat analogue control panel
If the appliance is not used for a long period, place on the
cowl cover and close the quick-acting valve in the gas supply
line and the gas cylinder.
Room temperature sensor
To measure the room temperature, an external room tempera-
ture sensor is located in the vehicle. The position of the sensor
is determined by the vehicle manufacturer depending on the
vehicle model. More information can be found in the operat-
ing instructions for your vehicle.
Figure 1
The temperature setting on the control panel depends on per-
sonal heating requirements and the design of the vehicle, and
must be determined individually.

In the event of a fault, the Truma CPplus VarioHeat control panel
immediately jumps to the “Fault” menu level and displays the
fault code of the fault. The cause of the fault can be deter-
mined and remedied with the aid of the troubleshooting guide
(from page 15 and ff).

E = Error
2 = Fault code
H = Appliance
H = Heater
A = Air conditioning system
Cause eliminated / return to the setting level
– Tap the rotary push button.
– The respective appliance is restarted.
This can take several minutes because of internal after-
runs of connected appliances.
If the cause has not been remedied, the fault will occur again
and the control panel will jump to the “Fault” menu level
again.
Cause not eliminated / return to the setting level
– Press the Back button.
In this case, the fault in the Truma CPplus VarioHeat
control panel is not acknowledged and the warning sym-
bol remains. The appliance remains in fault state. Other con-
nected appliances can be operated.

Manufacturer’s Warranty
(European Union)
1. Scope of Manufacturer’s Warranty
As the Manufacturer of the appliance, Truma undertakes a
warranty towards the Consumer that covers any material and/
or manufacturing defects of the appliance.
This Warranty is applicable in EU member states as well as in
Iceland, Norway, Switzerland and Turkey. A Consumer is the
natural person who was the first one to purchase the appliance
from the Manufacturer, OEM or dealer and who neither resold
the appliance in a commercial or self-employed professional
capacity nor installed it for a third party in such a capacity.
The Manufacturer’s Warranty covers any of the aforemen-
tioned defects that occur within 24 months upon concluding
the purchase agreement between the seller and the Con-
sumer. The Manufacturer or an authorised service partner
undertakes to remedy such defects through subsequent fulfil-
ment, i.e. at its discretion either by repairing or replacing the
defective item. Any defective parts shall become the property
of the Manufacturer or the authorised service partner. If the
appliance is no longer manufactured at the time of defect no-
tification and if replacement delivery has been opted for, then
the Manufacturer may deliver a similar product.
If the Manufacturer remedies a defect under its warranty
commitment, the term of the Warranty shall not recommence
anew with regard to the repaired or replaced parts; rather, the
original warranty period shall continue to be applicable to the
appliance. Only the Manufacturer itself and an authorised ser-
vice partner shall be entitled to conduct a warranty job. Any
costs that occur in the event of a warranty claim shall be set-
tled directly between the authorised service partner and the
Manufacturer. The Warranty does not cover additional costs
arising from complicated removal or installation jobs on the
appliance (e.g. dismantling of furnishings or parts of the vehi-
cle body), and neither does it cover travel expenses incurred
by the authorised service partner or the Manufacturer.
No further-reaching claims shall be permitted, especially dam-
age claims presented by the Consumer or third parties. This
provision shall not affect the validity of the German Product
Liability Act (Produkthaftungsgesetz).
Neither does the voluntary Manufacturer’s Warranty affect
the Consumer’s legally applicable claims for defects towards
the seller in the relevant country of purchase. In individual
countries there may be warranties that can be issued by the
relevant dealer (official distributor, Truma Partner). In such
cases the warranty can be implemented directly through the
dealer from whom the Consumer bought the appliance. The
warranty regulations of the country in which the appliance
was purchased by the Consumer for the first time shall also
be applicable.
2. Warranty exclusions
No warranty claim shall be applicable under the following
circumstances:
– Improper, unsuitable, faulty or negligent use and any use
that is not compliant with the intended purpose
– Improper installation, assembly or commissioning, contrary
to operating or installation instructions
– Improper operation or operation contrary to operating or
installation instructions, particularly any disregard for main-
tenance, care or warning notes,
– Instances where installations, repairs or any other proce-
dures have been conducted by non-authorised parties
– Consumable materials and parts which are subject to natu-
ral wear and tear
– Installation of replacement, supplementary or accessory
parts that are not original manufacturer’s parts or which have
not been approved by the manufacturer. If the appliance is
subject to networked control, this applies, in particular, if
the control units or the software have not been approved
by Truma or if the Truma control unit (e.g. Truma CP plus or
Truma iNet Box) has not been exclusively used for controlling
Truma appliances or appliances approved by Truma.
– Damage arising from foreign substances (e.g. oil or plasti-
cisers in the gas), chemical or electrochemical influences
in the water, or cases when the appliance has come into
contact with unsuitable substances (e.g. chemical products,
flammable substances or unsuitable cleaning agents)
– Damage caused by abnormal environmental or unsuitable
operating conditions
– Damage caused by force majeure or natural disasters or
any other influences not within Truma’s responsibility
– Damage resulting from improper transport
– End customer’s or third-party modifications of the appli-
ance, including any replacement, supplementary or acces-
sory parts, or installation of the same, especially concerning
the exhaust gas system or the cowl.
3. Making a warranty claim
The warranty must be claimed with an authorised service part-
ner or at the Truma Service Centre. All the relevant addresses
and phone numbers can be found at www.truma.com, in the
“Service” section.
The Manufacturer’s address is:
Truma Gerätetechnik GmbH & Co. KG
Truma Servicezentrum
Wernher-von-Braun-Straße 12
85640 Putzbrunn, Germany
To ensure a smooth procedure, we would be grateful if you
could have the following details ready before contacting us:
– Detailed description of the defect
– Serial number of the appliance
– Date of purchase
The authorised service partner or the Truma Service Centre
will then specify the further procedure. To avoid transport
damage, the affected appliance must only be shipped by prior
arrangement with the authorised service partner or the Truma
Service Centre.
If the warranty claim is recognised by the Manufacturer, then
the transport expenses shall be borne by the same. If no
warranty claim is applicable, the Consumer will be notified
accordingly and any repair and transport expenses shall then
be the Consumer’s liability. We ask you not to send in an ap-
pliance without prior arrangement.
