Assembly instructions for permanently
mounted trunk compartment heating systems
Please observe the Truma assembly instructions "Additional
truck heating systems" and "Trunk compartment heating sys-
tem E 4000 A" when using as a truck compartment heating
system.
In the case of vehicles used for commercial purposes, the
respective accident prevention regulations issued by the pro-
fessional associations are to be adhered to (e.g. for Germany
BGV D 34).
The assembly instructions "Trunk compartment heating sys-
tem E 4000 A" includes a form for the required "Confirmation
of installation by a specialist company".
Notes on installation in boats
Installation in boats must comply with the legal provisions of
the country of use (e.g. EN ISO 10239). National specifica-
tions and regulations (in Germany, for example, DVGW Work-
sheet G 608) must be respected.
The "Guidelines for the Construction, Installation, Testing and
Operation of Liquid Gas Systems for Household Purposes
on Inland Waterways" (BGR 146) must be complied with in
Germany. According to these guidelines the liquid gas system
must be installed by an engineer who has been approved by
the inland waterways employer's liability associations and
tested by experts belonging to these employer's liability insur-
ance associations.
In other countries always observe the respectively valid
regulations.
For further notes on installation, refer to the assembly instruc-
tions for the Trumatic E boat heater.
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.
For evenly distributed heating, the installation of the appliance
should be as much in the centre of the vehicle as possible
(or under the vehicle), and in such a way that the air distribu-
tion ducts can be routed with approximately the same length.
Cowls must always be fitted to prevent any waste gases en-
tering the inside of the vehicle. The waste gas must always be
guided to at least a side wall.

The wall cowl must be attached
so that no tank supports or tank
ventilation openings are found
within 500 mm (R). In addition,
no air discharge apertures
for the living area or window
openings may be located with
300 mm (R) of it.

When fitting the cowl within the
marked area below or next to
a window that must be open, an
electrical window switch
(part no. 34000-85800) must
be installed. 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).
Notes on skylights
With skylights (opening) the cowl top must project at least
10 cm above the opened window. If the cowl is located beside
the window, it is important to ensure that, depending on the
installation position (opening to the right or to the left), no
exhaust gases can enter the open window (e.g. through wind)
and that the cowl has sufficient draught air.
If the cowl is installed in the vicinity of the skylight, the instal-
lation of an electric window switch is compulsory (part no.
34000-85800). 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).
Notes on water supply
When installing a water supply into the vehicle, please ensure
that there is an adequate distance between the water hoses
and the heat source (e.g. heater, warm air duct).
A water hose may only be fitted at a clearance of 1.5 m to the
heater on the warm air duct. The Truma hose clip SC (part no.
40712-01) can be used if this distance is observed. In the case
of parallel installations, e.g. openings through a wall, a spacer
element should also be attached (e.g. insulation) to prevent
contact.
Exhaust duct
Trumatic E 4000 (A) heaters with wall or roof cowl must be
installed only with Truma exhaust duct AA 3 (part no. 39320-00) –
or Truma high-quality steel exhaust duct AEM 3 (part no.
39360-00) for boats – and air intake duct ZR (part no. 39580-00),
because the appliances have only been tested and approved
with these ducts.
New O-rings must installed each time the appliance has
been dismantled.
Permitted duct lengths
1. Inside installation with wall cowl
(see installation variant 2, page 2):
– Duct lengths up to max. 30 cm can be laid horizontally
or with a downward slope up to 5 cm.
– Duct lengths of up to max. 100 cm must be laid with an
upward slope of at east 5 cm to the wall cowl.
2. Inside installation with roof cowl
(see installation variant 3, page 2):
– Duct lengths of up to max. 200 cm must be routed
upwards at an angle of at least 45 degrees.
3. Under floor installation with wall cowl
R
(see installation variant 5, page 2):
– Duct lengths of up to 30 cm can be laid horizontally
or with a downward slope of up to 5 cm. Ducts must also
