Under-floor
assembly with
wall cowl kit
Refer to installation variant
Fig. 5 (page B).
Install wall cowl on as flat
a surface as possible on an
outside wall (vehicle apron)
(refer to „Inside installation
with wall cowl set").
If the wall cowl is in-
stalled using mounting
brackets, or such, under the
floor, the vehicle floor must
be sealed tight (refer to
„Interior installation with
floor cowl").
Interior installation
with floor cowl
Refer to installation variant
Fig. 3 (page B).
When using the floor cowl
always observe any restric-
tions given in the country-
specific regulations.
The appliance is only to be
assembled in upright posi-
tion. In vehicles designed for
residential purposes or in ve-
hicles with areas frequented
by persons on a short-term
basis, the vehicle floor must
be sealed tight and is to have
no openings to the interior,
e.g. vent openings for re-
frigerators, unsealed pedal
openings, ventilation valves,
hollow double floors. The
ventilation opening for the
gas cylinder box is not to be
in the floor, it must be routed
to the side, directly above the
floor, through the outer wall.
The floor cowl is not to lie
within the splash range of
the wheels (apply splash
guard, if necessary) and it
must be free-standing so as
to prevent supports, axles,
cross arms and such from
impairing the correct op-
eration. In addition, at least
three sides beneath the ve-
hicle floor must be open in
order to ensure unhindered
escape of the exhaust gas.

Assembly of the
floor cowl
Fig. B1: The rectangular
opening for the exhaust gas
outlet (30) must be right-an-
gles to the direction of travel.
No modifications must
be carried out to the
floor cowl!
Drill an 83 diameter opening
in the vehicle floor. Coat the
space between the cowl and
the vehicle floor with plastic
coachwork sealing agent (31) –
do not use silicone! Secure
the floor cowl (32) with
4 screws (33).
Outside installation
with floor cowl
Refer to installation variant
Fig. 4 (page B).
The appliance is only to be
assembled with cowl con-
nec-tion fitting pointing
vertically down. The appli-
ance can be installed on the
outside of the vehicle, on a
perpendicular wall (e.g. on
the cab rear wall or on the
body fire wall of a truck). In
articulated vehicles always
pay attention to suffi-cient
spacing between the cab
rear wall and the semi-trailer
(observe rotary and
articulation movements).
Assembly of the
floor cowl
Fig. C: Slide the cowl (32)
over the O-ring onto the
exhaust gas connection fit-
ting (35) on the heating unit.
The side-facing rectangular
openings (30) must be at
right-angles to the direction
of travel. Apply four flange
borings to the heater casing,
drill through them with
a short drill 2.5 mm in
diameter and fasten the
cowl with 4 screws (33).
Fastening the
heating appliance
Inside installation with
wall cowl or roof cowl
Fig. D: Depending on the
installation site, bolt the heat-
ing appliance securely with
the fastening straps (a) or
angle pieces (b) supplied.
Inside installation
with floor cowl
Where a floor cowl is used,
place the appliance on the
cowl opening and screw
tight with 4 angle pieces
(see Fig. B2).
Outside installation
Fig. E: Assemble with the
aid of the asembly mount.
Fasten both mounts (36)
securely and firmly to the ve-
hicle with through bolts not
less than M 5 in size. Fasten
the U-beam (37) to the out-
side of the heater with the
bolts supplied (38). Fasten
the heater with 4 M 6 x 10
bolts (39) and self-locking
nuts. Fasten two protective
caps (40) to the outside of
the vehicle.
In order to drain condensa-
tion water, drill a hole 8 mm
in diameter at the lowest
point in the heater casing
some 20 mm from the edge.
Ensure that the drill does not
penetrate more than 10 mm
in order to prevent damage
to any internal components.
Fit the rubber connection
fitting supplied (it projects
about 4 cm downward –
Fig. C, D + E: d).
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 heat-
ing device can be drawn in.
It must be ensured by means
of construction design that
the heating air introduced in-
to the vehicle is not polluted
(e.g. by oil vapour). This is
achieved, for example, with
air heaters with circulating air
operation, both for interior
installations and for external
installations. (In heaters with
fresh air operation the fresh
air is not to come from the
engine compartment, from
the vicinity of the exhaust
or the exhaust outlet of the
heater.)
Fig. F: The hot air (W) is ex-
pelled from 2 vents, either
directly or via a hot air duct
VR (diameter 72 mm).
From the appliance to the
first air outlet install only VR
duct (72 mm diameter) with
a maximum length of approx.
1.5 m. To prevent overheat-
ing, the first air outlet must
be non-sealable (swivelling
vent SCW 2, end support
ENE). ÜR duct (65 mm diam-
eter) can also be laid after
the first air outlet. Hot air
ducts whose surface temper-
ature exceeds 80 degrees C
(especially as far as the first
air outlet in the case of the
E 4000) must be protected
from contact by cladding
with a duct insulator (such as
Truma l 80). Secure all duct
connections with self-tap-
ping screws. Fasten ducts
with clamps.
The warm air system is de-
signed for each type of vehi-
cle individually, on a modular
basis. There is an extensive
accessories program avail-
able (refer to brochure). You
can obtain sketch diagrams
free of charge from the
Truma Service Centre, show-
ing optimal installation sug-
gestions for warm air
systems in all current-type
caravans and mobile homes.
