Safety instructions
The use of upright gas cylinders from which gas is taken in
the gas phase is mandatory for the operation of gas regu-
lators, 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.
If the gas system is leaking or if there is a smell of gas:
– extinguish all flames
– do not smoke
– switch off the appliances
– shut off the gas cylinder
– open windows and door
– do not actuate any electrical switches
– have the entire system checked by an expert!
Repairs may only be carried out by an expert!
A new O-ring must always be installed after dismantling the
exhaust duct!
Guarantee claims, warranty claims and acceptance of liability
will be ruled out in the event of the following:
– modifications to the unit (including accessories),
– modifications to the exhaust duct and the cowl,
– failure to use original Truma parts as replacement parts and
accessories,
– failure to follow the installation and operating instructions.
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 (2.75 kPa) must be the
same as the unit´s operating pressure (see type plate).
LPG Systems and pressure regulators must comply with
the technical and administrative regulations of the country
in which the appliance is used. For your own safety it is
absolutely necessary to have the complete gas installation
regularly checked by an expert (at least every 2 years).
The vehicle owner is always responsible for arranging
the gas inspection.
Pressure regulating equipment and hoses must be replaced
with new ones no more than 10 years after the date of
manufacture. This is the responsibility of the operator.
Liquid gas equipment must not be used when refuelling, 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.
This will be remedied by running the heater and ensuring ade-
quate room ventilation.
If the burner makes an unusual noise, it is likely that the
gas pressure regulator is faulty and it is essential to have it
checked.
Do not place articles on or against this appliance.
Do not use or store flammable materials near this appliance.
Do not spray aerosols in the vicinity of this appliance while it
is in operation.
For the gas supply, only a pressure regulator with a fixed de-
livery pressure of 2.75 kPa may be used.
The flow rate of the pressure control device must correspond
to at least the maximum consumption of all devices installed
by the system manufacturer.
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 regular-
ly for brittleness. Winter-proof special hoses must always be
used if the equipment is operated during the winter.
Important operating notes
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 conducting exhaust gas and sup-
plying combustion air, free from contamination (slush, leaves
etc.).
The installed temperature limiter shuts off the gas supply if
the appliance becomes too hot. Therefore do not shut the
warm air outlets and the opening for the returning circulating
air.
The cabin air flow through the heater must not be restricted in
any way. Do not use any after market air filters or air grills.
The use of such components may cause the unit to over heat.
Warning: Air from the discharge vent may be hot. Do not
place combustible materials directly in front of the discharge
vent. Keep curtains, bedding and other flammable materials
away from the vent.
Always use original Truma parts for maintenance and repair
work!

4
Always observe the operating instructions and “Impor-
tant 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 ap-
pliance, 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.

Adjust desired room temperature at rotary knob.
Switching the heating on:
Set the rotary switch to (d).
Switching on the Ventilation
Set the rotary switch to (b).
Switching off
Set the rotary switch (a) to the centre (c). If the appliance is
switched off after a heating phase, the fan can continue run-
ning in order to make use of the residual heat.
If the appliance is not used for a prolonged period of time,
close quick-acting valve in the gas supply line and turn off
gas cylinder.
Green LED “Operation”
(under rotary control knob)
When the appliance is switched on (heating or ventilation)
the green LED must be illuminated (the fan is running). If the
LED is not illuminated, possibly check the (main) switch. For
this purpose observe respective instructions of the vehicle
manufacturer.
During the heating operation, while the flame is burning, the
green LED lights up with twice the intensity. This also makes
it possible to determine the instantaneous switching point of
the room temperature.
Operating instructions Fuses
The device and control panel fuses are on the electronic con-
trol unit on the device.
Device fuse (F1):
3.15 AT – slow –
Control panel fuse (F3):
1.6 AT – slow –
The fine-wire fuse must only be replaced by a fuse of the
same design.
Red LED “Failure”
Should a failure occur, the red LED is illuminated permanently.
Possible causes for the failure can be e.g. no gas, insufficient
combustion air, heavily soiled fan, defective fuse etc.. Deacti-
vate by switching off and then switching on again.
Flash operation indicates that the operating voltage is
too low (charge battery, if necessary) or too high for the
appliance.
Maintenance
The unit must be checked annually for contamination (dust,
dirt, debris) by an expert and cleaned if necessary.
Servicing shall be carried out only by authorised
personnel.

Installation instructions Choice of location
Always install the appliance and its exhaust duct in such a
way that it is always easily accessible for service work and
can be removed and installed easily.
This appliance can be installed without any clearance to com-
bustible materials providing the surrounding materials will
withstand temperatures of up to 85 °C. The flue and warm air
ducts can also be installed without clearance providing only
Truma components supplied with the appliance are fitted.
Make sure that there is at least 10 mm clearance to com-
bustible materials around the warm air discharge vent and
500 mm in front of the vent. Locate the vent so that curtains,
bedding, etc. cannot be blown directly in front of or in contact
with the warm air vent.
Steps must be taken to ensure that the warm air outlet of the
heating system is never obstructed (see warm air distribution).
The installation space must have appropriate openings for the
circulating air return (see circulating air return).
Locate the heater in such a way that the cowl can be mount-
ed on the outside on a surface which is as straight and
smooth as possible.
For evenly distributed heating, the installation of the appliance
should be as much in the centre of the vehicle as possible,
and in such a way that the air distribution ducts can be routed
with approximately the same length.
The cowl must be placed in such a way that the exhaust gas
cannot find its way into the vehicle interior. The exhaust gas
cowl can only be installed through a vertical wall to the
outside, never through a horizontal surface.
The flue cowl must always vent to outdoors and
not into any annex or other enclosed area.
This outside surface must be exposed to wind from all
directions and, if possible, there should be no trim strips or
covers in this area, mount heater on an appropriate base,
if necessary.
The wall cowl is to be fitted in such a way that no tank nozzles
or tank ventilation apertures are located within 500 mm (R) of
it. In addition, no air discharge apertures for the living area or
window openings may be located with 300 mm of it.
300 mm
300 mm
R
If installing the cowl directly underneath a window
that will be opened, installation of an electric window
switch (part no. 34000-85800) is mandatory. The gas unit
must automatically switch itself off using the Truma automatic
shut-off facility if the window is opened (Accessories, part no.
39050-00800).
Refer to AS 5601/2004 – Gas Installations, for location re-
quirements of the flue terminal.

8
Exhaust duct
With the Trumatic E 2400 (Australia) only use the Truma ex-
haust duct AA 24 (part no. 39420-00) with wall cowl and the
combustion air supply duct ZR 24 (part no. 39440-00) for the
installation, as the appliance has only been tested and ap-
proved with these ducts.
A new O-ring must always be installed after dismantling
the exhaust duct!
Permissible duct lengths
Interior installation with wall cowl
(refer to installation variant 1, page 2):
– Duct lengths of up to max. 70 cm can be routed as
ascending duct in any way required, or descending by max.
30 cm.
– Duct lengths from 30 cm to max. 100 cm must be rout-
ed as ascending duct with an ascending angle of min. 45°.
Interior installation using the wall cowl
kit
Refer to installation variant, Fig 1 (page 2).
Assembly of wall cowl
Assemble wall cowl on a surface which is as flat as possible
and which is exposed to wind from all directions. Drill an
opening (8) measuring 70 mm in diameter (pack wood into
hollow spaces in the area of the cowl opening). Use the pro-
vided rubber seal (10) for sealing. In the event of structured
surfaces, coat with plastic body sealant – do not use silicone.
In the event of a greater wall thickness, first connect the
exhaust double duct to the cowl from the outside.
Slide rubber seal (10) and clamp (4) onto the cowl inner
part (11).

duct (5) on the connection fitting (6) using clamp (7).
Always install a new O-ring following any disassembly!

9
Warm air distribution and circulating air
return with interior installation
Warm air distribution
Hot air suction apertures must be arranged in such a way that
no exhaust gases from the engine or the heating device can
be drawn in. It must be ensured by means of construction
design that the heating air introduced into the vehicle is not
polluted (e.g. by oil vapour). This is achieved, for example,
with air heaters with circulating air operation.
Only use original Truma parts for ducting, outlets, fit-
tings and accessories, supplied by Dometic or Truma.
Do not use any other parts.
The warm air (W) is blown out from the appliance, either
directly or using a warm air duct VR 80 (80 mm diameter).
Remove grating from warm air outlet of the appliance. Con-
nect duct VR 80 (80 mm diameter). By positioning a manifold
section, the ducts VR 72 (72 mm diameter), ÜR (65 mm dia-
meter) or ZR 18 (49 mm diameter) can also be added on.
Use the following table to determine the number of required
air openings in the warm air duct.
Duct length* Number of air openings
up to and
including 1 m at least 1 air opening
over 1 m
up to 5 m at least 2 air openings (the first air opening after max. 1 m)
5 m a more at least 3 air openings
(the first air opening after max. 1 m)
* In the case of duct branches, the sum of the installed warm
air ducts.
In order to avoid overheating, there must be at least
one air passage which is always open (swivel
nozzle SCW 2).
Secure all duct connections with self-tapping screws. Fasten
ducts with clamps.
The hot air system is individually designed for each vehicle
model using a modular principle. A wide range of accessories
is available for this purpose.
Circulating air return
The circulating air (U) is sucked back into the appliance, either
directly or via a duct piece VR 80 (80 mm diameter).
1. Direct intake: If the appliance is installed in a storage
compartment or such, drill two holes measuring 75 mm in
diameter into it, or make a corresponding opening for the
circulating air return.
Do not obstruct the air passage to the appliance!
2. Circulating air outside the storage area can be drawn in via
a duct piece VR 80 (1) 80 mm diameter (max. 100 cm in
length) and returned to the appliance. The storage compart-
ment can then be used to the full.
Remove protective grating from the connection fitting (3).
Insert duct piece (1) into the grating connection fitting and
fasten using the available screws. Attach swivel nozzle SCW 2
to the duct end (4).

Fitting the control panel
Any modification made to the Truma components
pertaining to this will lead to the cancellation of the
guarantee and to the exclusion of any claims for liability.
The installer (manufacturer) is responsible for providing oper-
ating instructions for the user as well as for the labelling of
the control panels!
When selecting the location, take note that the control panels
must not be subjected to any direct radiant heat. Length of
the connection cable 4 m or 10 m.
Selecting the position of the thermostat is very impor-
tant, the reading of the air temperature is taken by the
thermostat, therefore the position of the thermostat needs
to be considered. The thermostat must be placed in an area
away from sunlight or any external source of heat. The posi-
tion should be chosen to represent the average air tempera-
ture experienced inside the vehicle.
If installation is only possible behind curtains or in similar
locations with temperature fluctuations, a remote sensor for
the ambient temperature must be used (Accessories).
Installing the control panel with rotary switch
If flush mounting is not possible, Truma will supply an
on-surface frame (1 – part no. 40000-52600) as an ac-
cessory on request.
Drill a hole Ø 55 mm in diameter.
Plug the control panel cable (2) into the control panel (3) and
then fit the rear cover cap (4) as a stress-relieving device.
Push the cable through to the rear and lay it to the electronic
control unit.
Secure the control panel with four screws (5) and fit the cover
frame (6) in place.
Truma offers side parts (7) in eight different colors for
finishing the cover frames (6) in a visually pleasing way.
Please ask your dealer.

Fitting the electronic control units
Unscrew the cover of the control units (A and B).
The plugs on the electronic control units should only be
withdrawn or plugged in if the supply voltage had been
disconnected beforehand. Pull the plug out straight!
Insert the plug on the control panel cable (1) as shown in the
diagram onto the red terminal strip of the control unit (A).
Insert plug (2) – 20-pin – in the grey terminal strip on the
control unit (A).
Insert plug (3) – 10-pin – in the red terminal strip on the
control unit (B).
If a timer switch or a remote sensor is fitted, its plug
is to be inserted on the black terminal strip (control
unit – A). If several accessory components are being used at
the same time, connection is effected via the multiple box
(Accessories).
Secure the lower parts with two screws at an easily accessi-
ble location, protected against moisture (must not be heated
to above 65 °C).
Screw the cover of the control units into place.
Electrical connection 12 V
Electric cables, switching units and control units for heaters
must be arranged in the vehicle in such a way that their satis-
factory operation cannot be adversely affected under normal
operating conditions. All cables leading to the outside must
be splash proof at the leadthrough opening.
Prior to working on electric components the appliance
must be disconnected from the power supply. Switch-
ing off at the control panel is not sufficient!
When carrying out electric welding work on the body the
appliance connection must be disconnected from the vehicle
electrical system.
If the connections are transposed there is a risk of cable
burning. This also rules out any guarantee or liability
claims!
The red cable is positive, the blue cable is negative!
Connect the appliance to the fused vehicle electrical system
(central electrical system 5 – 10 A) using the 2 x 1.5 mm2
cable, for lengths over 6 m use 2 x 2.5 mm2cable. Negative
cable to central ground. For direct connection to the battery
the positive and negative cable must be fused. Connections in
Faston terminals, fully insulated (motor vehicle flat connector
