Truma Combination Boiler
The Truma Combination Boiler has been
designed to run on gas or electric power and
the optimum performance is obtained when
used in dual fuel mode, that is running on
gas and electric at the same time.
Running in dual fuel mode has the following
benefits:
• Fastest possible heat up time, the 2KW
gas burner combines with a 1.8KW electric
element to provide 3.8KW of energy to heat
your hot water and warm your caravan.
• The intelligent heat management system
automatically senses when the water and
room are nearing the required temperature
and then automatically turns off your gas
burner and operates solely electric power,
conserving your gas.
• As hot water is used or the room cools the
Truma combination heater will continue to
operate on electric only until a point where
the demands necessitate that additional
gas power is required. An example for
such a demand could be for instance if the
exterior door was left open and the room
temperature dropped by 10 degrees in the
space of a few minutes, in this case the
intelligent heat management system would
decide that the best way to get the room
back to the required temperature would be
to use both gas and electric at the same
time.
Operating the Truma Combination system on
electric or gas only will result in longer heat up
times for hot water and the room temperature
n comparison to operating on dual fuel.
Operating on electric only may not in all cases
maintain a comfortable room temperature
especially in colder conditions.

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
TRUMA COMBI 4E

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
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.
! WARNING: Care should be taken
to ensure adequate ventilation of the flue
at all times. It is inadvisable to inhale
exhaust fumes.
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.

Filling the water heater
Check if the rotary switch for the drain valve
(FrostControl) is set to ‘Operation’, meaning
that it is parallel to the water connection
and engaged.
When the temperature at FrostControl is below
about 7° C, first switch on the heater to warm
the installation compartment and FrostControl.
After several minutes, when the temperature at
FrostControl is above 7° C, the drain valve can
be closed.
Close the drain valve by pushing the push
button until it engages. Switch on power for
water pump (main switch or pump switch).
Open hot water taps in kitchen and bathroom,
(set preselecting mixing taps or single-lever fittings
to ‘hot’). Leave the fittings open for as long as it
takes for the boiler to displace the air and fill up,
and the water to flow without interruption.
If just the cold water system is being operated,
without using the water heater, the heater tank
also fills up with water. To avoid frost damage,
the boiler must be drained through the drain
valve, even if it was not operated. 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
Switch off power to water pump (main or
pump switch).
Open hot water taps in kitchen and bathroom.
Turn the yellow boiler drain valve to the up
position to dump the water.
The boiler is now drained directly to the
outside via the drain valve. Place a bucket
beneath the outlet to check whether the
water content has completely drained away
(10 litres). There shall be no claims under
guarantee for damage caused by frost!
Maintenance
Only original Truma parts may be used for
maintenance and repair work!
The water container used is made of stainless
steel, which is foodstuff-compatible.
Use wine vinegar for descaling the water heater,
this being introduced into the appliance via the
water supply. Allow the product to react and
then thoroughly flush out the appliance with
plenty of fresh water. For sterilization purposes
we recommend ‘Certisil-Argento’; other
products (especially those containing chlorine)
are unsuitable and may damage the unit.
To avoid microorganisms colonizing the water
in the boiler, heat the water to 70° C at regular
intervals (at least once per year).
Move the rotary switch on the control panel
to position (c – summer operation) 60° C. The
green (b) and yellow (g) LEDs light up.
Once the water in the boiler has reached a
temperature of 60° C, the burner will switch
off and the yellow LED (g) will go out. The unit
must stay switched on for at least 30 minutes
and no warm water may be removed. The
residual heat in the heat exchanger will heat
the water up to 70° C.
Fuses
The unit’s fuse is located on the electronics
under the connection cover. Replace the unit’s
fuse only with an identical fuse.
Device fuse: 10 A – slow – (T 10 A)

Troubleshooting
For troubleshooting a fault please refer to page 9
of the Truma Combi 4E Operator Manual.
Truma Heating System and Air Flow
The Swift Group undertakes considerable
testing of our products in cold chambers to
ensure they are usable in cold temperatures.
During this testing, the air flow on the blown
air outlets is defined and set by us. In some
cases, customers may wish to alter this setup
to achieve a different heating pattern (i.e. more
hot air to the rear of the vehicle or vice-versa)
and this can be achieved by placing restrictors
in the blown air system.
Customers should seek the advice of Truma or
their Dealer on how to do this.

Note: Refrigerators manufactured by
Dometic GmbH are free of CFC/HCFC
and HFC. Ammonia (a natural compound
of hydrogen and nitrogen) is used in the
cooling unit as a coolant. Non-ozonehazardous cyclopentane is used as a
propellant for manufacturing PU foam
insulation.
In order to ensure that the recyclable packaging
materials are re-used, they should be sent to
the customary local collection system.
The appliance should be transferred to a
suitable waste disposal company that will
ensure re-use of the recyclable components
and proper disposal of the rest. For ecofriendly draining of the coolant from all
absorber refrigeration units, a suitable disposal
plant should be used.
Energy-saving tips
• At an average ambient temperature of 25°C,
it is sufficient to operate the refrigerator at
middle thermostat setting.
• Where possible, always store precooled
products.
• Do not expose the refrigerator to direct
sunlight.
• Ensure that air circulation of the cooling unit
is not obstructed.
