Regulations

Guarantee claims, warranty claims and acceptance 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
– Failure to use original Truma parts as replacement parts and
accessories
– Failure to follow the installation and operating instructions.
This may also invalidate the device operating permit, which in
many countries also denotes cancellation of the vehicle oper-
ating permit.
The year when the equipment was first taken into opera-
tion must be indicated with a cross on the type plate (66).
The installation of the device in vehicles must comply with
the technical and administrative regulations of the respective
country of use (e.g. EN 1949). The national legislation and
regulations (e.g. DVGW Work Sheet G 607 in Germany) must
be observed.
More information about the regulations in the relevant desti-
nation countries can be requested from our foreign represent-
atives (see www.truma.com).

Special information for installation

The device and its exhaust duct must always be installed so
that they are easy to access at all times for service work, and
also easy to remove and install.

Location of the heater

The driver must not come into contact with the heater from
his seat. The heater must not be installed directly behind the
driver's seat.
Using the installation template, check whether the floor cut-
out for the combustion air intake should be on the left or the
right. The combustion air must not be taken from the
vehicle interior. The combustion air must always be
supplied from outside. The combustion air intake must
not be subjected to wheel spray, otherwise fit a spray
guard.
The floor cut-out for the device must be installed so that
no contaminated air (exhaust fumes, petrol vapour or
oil vapour) can penetrate the interior of the vehicle.
There must not be any heat-sensitive materials be-
neath the device (cut out the carpet floor). On PVC
floors, discolouration may occur due to heating of the heater
base. There must also be no flammable / heat-sensitive mate-
rials on the vehicle underbody close to the combustion air
infeed.
If the heater is installed on a floor base, false floor or the
like, it is essential to use the air intake extension (part
no.30030-04800, length 50 cm). The air intake extension must
protrude into the air flow approx 5 to 10 cm below the lowest
part of the vehicle (pay attention to ground clearance of the
vehicle). 2 air intake extensions are required for the S 5004.
The floor base or false floor must be sealed off from the ve-
hicle interior and made from non-combustible material, or
have an inner lining made from sheet metal. To prevent the
accumulation of unburnt gas, the floor base must have
a vent of at least 2cm² at the lowest point or be open at the
bottom.

Location of the roof cowl

The heater must always be operated with a roof cowl.
This must always be installed vertically or with a maxi-
mum incline of 15 degrees!
The location of the roof cowl must be chosen so that it is in
the air flow at all times during heater operation. Roof struc-
tures may interfere with the function of the heater.
The manufacturer of the vehicle or heater installer must deter-
mine a combination of cowl top / extension depending on the
installation situation in the vehicle by means of test drives and
coordinate this with Truma if necessary. Depending on the ve-
hicle model and the roof structures, a T2 (part no. 30700-02) or
T3 (part no. 30700-03) cowl top may be required. The T3 cowl
top has been specially developed for motor homes.
If necessary, an AKV cowl extension (part no. 30010-20800)
must also be installed. This must be secured with a screw.
An open roof window / sun roof in the vicinity of the
roof cowl may allow exhaust gas to penetrate the interi-
or of the vehicle. The cowl must therefore never be positioned
near this opening. If this is not completely possible, the heater
must not be used when the roof window / sun roof is open. In
order to make this clear, the installer must also affix a sticker
(part no. 30090-37100) to the roof window / sun roof in a
clearly visible location.

Electrical connection (optional)

A 12 V power supply is not required to operate an S 3004
heater with piezo ignitor (S 3004 P) or auto ignitor (1.5 V).
12 V connection
If a Truma TEB-3 fan or lighting for the control panels is in-
stalled, a 12 V mains supply is required (alternating current
ripple is < 1.2 Vpp).
The heater must be connected to the fuse-protected on-board
power supply (5 A).
230 V connection ~, 50 Hz
When using a Truma TN-3 fan, a connection to the 230 V AC
supply and an external control panel are needed.
Safety instructions
The unit must only be installed and repaired by an expert.
Make sure that the power supply is disconnected! Pull out the
mains plug!
In-vehicle installations must comply with the technical and
administrative regulations of the respective country of use
(e.g. EN 1648, VDE 0100-721). National regulations and rules
must be followed.
