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 heat-
ing, the installation of the ap-
pliance should be as much in
the centre of the vehicle as
possible (or under the vehi-
cle), 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 exhaust gas
cannot find its way into the
vehicle interior.
Fig. A1: The wall cowl is to
be fitted in such a way that
no tank nozzles or tank ven-
tilation 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 (R) of
it. If the cowl is fitted directly
beneath a window which
is to be opened, the device
must be fitted with an auto-
matic disconnection device.
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 1, page B):
– Duct lengths up to max.
30 cm can be laid horizon-
tally 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 2, page B):
– 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 (see instal-
lation variant 5, page B):
– Duct lengths of up to
30 cm can be laid horizon-
tally or with a downward
slope of up to 5 cm. Ducts
must also be protected
against damage from
flying stones.
Inside installation
with wall cowl set
See installation variant Fig. 1
(page B)
Installation of wall cowl
Fig. A2: Choose a wall
which is as straight as pos-
sible and which is well
exposed to wind from all
directions. Drill an opening of
83 mm diame ter (pack wood
into any hol low spaces in the
area of the cowl opening).
Use the en closed rubber seal
(8) for sealing. In the event of
structured surfaces coat with
plastic body sealant – do not
use silicone!
Slide clamp (7) over the
ducts prior to passing the
exhaust double duct through
the opening.
Slide rubber seal (8 – smooth
side toward cowl, sealing
lips toward wall) and clip
(4) onto inner section of cowl
(9). Press together end of ex-
haust duct (1) so that winding
touches winding, and slide
over O-ring (10) onto the
connection fitting (11 – bend
pointing up).
Slide holes of clip (4) onto
pins of muff (11 – screw fac-
ing downwards) and screw
in place. Slide combustion
air intake duct (5) on the ser-
rated connection fitting (12).
Fasten cowl inner part (9)
with 6 self-tapping screws
(14), mount cowl outer part
(15) and fasten with 2 screws
(16).
Fasten combustion air intake
duct with clamp (7), from the
inside, on the connection
fitting (12).
Fasten cowl double duct to
the wall with at least one
clamp ZRS (17).
Double cowl duct
connection to the
heating appliance
Fig. A4: Slide clip (7) over
the pipes. First compress the
exhaust duct (1) so that the
coil windings are pressed
against each other. Slide the
clamp (4) over the exhaust
duct (1). Slide the exhaust
duct onto the connection
fitting (2) over the O-ring. En-
gage the clamp (4) and screw
tight. Secure the air intake
duct (5) on the connection
fitting (6) with clamp (7).
Inside installation
with roof cowl set
See installation variant Fig. 2
(page B).
Install roof cowl on a surface
which is as straight as pos-
sible, with wind flow from all
sides. From the appliance to
the cowl it must be possible
to have a direct duct route
rising over the entire duct
length (max. 2 m)!
Assembling the
condensate trap
A condensate trap has to be
installed between the heater
and the double duct to allow
condensation water and rain
water to drain away.
The exhaust gas double
duct must not sag – the
condensate trap must be the
lowest point!
Fig. A3: Fully open the
clamp (4) and slide over the
O-ring onto the exhaust gas
connection fitting (2). Slide
the exhaust coupling (17)
over the O-ring onto the ex-
haust gas connection fitting
(2 – if the condensate trap is
installed on a level with the
heater, the drain (18) must
be facing down). Engage the
clamp (4) and screw tight.
Tighten the drain (18).
Assembling the
roof cowl
Fig. A3: Drill a hole (8) with
diameter 83 mm (any hollow
compartments in the vicinity
of the cowl hole should be
lined with wood). Seal with
rubber seal supplied (22).
Coat textured surfaces with
a plastic coachwork sealing
agent (not silicon).
If the roof cowl is relatively
thick, first connect the ex-
haust gas double duct from
the outside onto the cowl.
Slide the rubber seal (22) and
clamp (4) onto the inner cowl
section (23). First compress
the exhaust duct (1) so that
the coil windings are pressed
against each other, then slide
over the O-ring onto the con-
nection fitting (24). Engage
the clamp (4) and screw
tight.
Slide the air intake duct (5)
onto the serrated connection
fitting and secure with the
black screw (25).
Fasten the cowl section (23)
with 6 bolts (26). Mount cowl
roof (27) and secure using
2 bolts (28).
The exhaust vents in
the cowl roof must face
at right-angles to the
direction of travel.
Always keep the cap (29)
on when the heater is not
operating.
Double duct
connection to the
heating appliance
Fig. A3: Press end of ex-
haust duct (1) together so
that winding touches wind-
ing. Slide clamp (4) over
exhaust duct (1). Pass the
exhaust duct (1) via the
O-ring and fit it to the ex-
haust coupling (17). Engage
the exhaust duct tightener
(4) onto the exhaust coupling
(17) and secure. Take the
connection fitting (19) with
the wide side over the ex-
haust duct and slide it firmly
onto the air connection fit-
ting (6) on the heating unit.
Line up the opening in the
connection fitting (19) with
the drain (18). Screw in and
tighten connection fitting
(20).
Slide the air intake duct (5)
firmly onto the connection
fitting (19) and fasten with
duct clamp (7).
Drill a 10 mm diameter open-
ing in the vehicle floor for
the condensate hose (21).
Fasten the condensate hose
onto the connection fitting
(20) and pass it through the
opening.
Due to the risk of frost
in winter, the hose
should not project more than
2 cm below the vehicle floor!
