refueling, in multi-storey car parks, in garages, 
or on ferries.
During the initial operation of a brand new 
appliance (or after it has not been used for 
some time), a slight amount of fumes and 
smell may be noticed for a short while. It is a 
good idea to heat the device up several times 
in summer operation (60° C) and to make sure 
that the area is well ventilated.
Heat-sensitive objects such as spray cans 

or flammable liquids may not be stored in 

the same compartment where the heater is 
installed because, under certain conditions, this 
area may be subject to elevated temperatures.
Only pressure regulating equipment that 

complies with EN 12864 (in vehicles) with fixed 

output pressure of 30 mbar may be used for 

the gas system. The flow rate of the pressure 

control device must correspond to at least the 
maximum consumption of all devices installed 
by the system manufacturer.
For vehicles, we recommend Truma’s 

SecuMotion gas pressure regulator; for the 

two-cylinder gas system we also recommend 
the Truma DuoComfort changeover valve.
At temperatures below 5° C, the gas pressure 
regulator or the changeover valve should be 
used with EisEx regulator heating.
Controller connecting hoses that meet national 
regulations must always be used in the 

respective country for which the equipment 
is destined. These hoses must be checked 
regularly for brittleness. Winter-proof special 
hoses must always be used if the equipment is 
operated during the winter.
Pressure regulating equipment and hoses 
must be replaced with new ones no more 
than 10 years after the date of manufacture 
(every 8 years if used commercially). This is the 
responsibility of the operator.

do not use the boiler water as drinking water!

Important operating notes

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.
The integrity and tight fit of the exhaust gas 
double duct must be checked regularly, 
particularly at the end of long trips. Also check 
the mounting of the appliance and the cowl. 
Following a blow-back (misfire) always have the 
exhaust gas system checked by an expert!
Always keep the cowl for the exhaust duct and 
combustion air intake free of contamination 
(slush, ice, leaves etc.). The warm air outlets 
and the openings for circulation air return must 
be unobstructed so the unit will not overheat. 
The integrated temperature limiter blocks the 

gas supply when the unit becomes too hot.
Directive 2004/78/EC stipulates that a safety 
shut-off device is required if motor homes are 
being heated while driving.

The Truma SecuMotion gas pressure regulator 

meets this requirement.

note: If the truma Secumotion gas pressure 
regulator is not installed, the gas cylinder 
must be closed while driving and warning 
signs must be in place in the gas cylinder 
protection box and near the control panel.

The safety shut-off device is also recommended 
for safety reasons if motorhomes are being 
heated while driving.

operating Instructions

Always observe the operating instructions and 
‘Important operating notes’ prior to starting! 
The vehicle owner is responsible for the correct 
operation of the appliance.
The installer or vehicle owner must apply the 
yellow sticker with the warning information, 
which is enclosed with the appliance, to a place 
in the vehicle where it is clearly visible to all 
users (e.g. on the wardrobe door)! Ask Truma to 
send you stickers, if necessary.

Before using for the first time, it is essential 
to flush the entire water supply through with 

clean warm water. If the heater is not being

function description

The liquid gas heater ‘Truma Combi’ is a 
warm-air heater with integrated hot water boiler 
(10 litre volume). The burner operates fan-
supported, which ensures trouble-free function 
even when on the move.
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.
– In summer operation, the water contents 
are heated in the smallest burner stage. Once 
the water temperature is reached, the burner 
switches off.
– 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 temperature depends on the selected 
operational mode and the heater output.
At a temperature of approximately 3° C at the 
automatic FrostControl safety/drain valve, the 
valve will open and drain the boiler.

The unit is not suitable for use as a flow heater.

Safety instructions

If the gas system is leaking or if there is a  
smell of gas:

– extinguish all open flames

– open windows and door 
– close all quick-acting valves and gas cylinders 
– do not smoke 
– do not activate any electric switches 
– ask an expert to inspect the entire system!

repairs may only be carried out by an 
expert!

Any modifications to the unit, including 
accessories, exhaust duct, and cowl, or the 
use of spare parts and accessories that are 
important to the operation of the system that 
are not original Truma parts and failure to follow 
the installation and operating instructions will 
cancel the warranty and indemnify Truma from 
any liability claims. It also becomes illegal to 
use the appliance, and in some countries this 
even makes it illegal to use the vehicle.
The gas supply’s operating pressure (30 mbar) 
must be the same as the unit’s operating 
pressure (see type plate).
The vehicle owner is always responsible for 
arranging the inspection.
Liquid gas equipment may not be used when
