if the window is opened
(special accessory Part no.
34000-80800).
Exhaust duct
For the Trumatic C only use
the Truma exhaust duct AA 3
(Part no. 39320-00) or, for
boat installation, the Truma
stainless steel exhaust duct
AEM 3 (Part no. 39360-00)
and the combustion air
sup ply duct ZR (Part no.
39580-00), as the appliance
has only been tested and
approved with these ducts.
The length specifi-
cations refer to the
combusti on air intake duct.
Cut ducts to lengths so that
these project out of the
opening for the cowl during
installation. Cut the exhaust
duct (Fig. E: 1) so that it is
10 cm longer. This avoids
elongation and a tension load
on the exhaust duct.
Always install a new
O-ring following any
disassembly.
Permissible duct
lengths
Fig. A 1:
For the wall cowl
the duct lengths can be rout-
ed from min. 70 cm to max.
100 cm as ascending duct in
whichever way required, or
descending by max. 5 cm.
Duct lengths of min. 100 cm
to max. 150 cm must be
ascending at an angle of at
least 45°.
Fig. A 2:
Roof cowl duct
lengths of up to max. 230 cm
must be ascending at an an-
gle of at least 45°.
Connection of the
exhaust double duct
to the appliance
Fig. D:
Press end of exhaust
duct (1) together so that win-
ding touches winding. Slide
clamp (4) onto connecting
piece (3) and engage. Slide
clamp (7) over the combus-
tion air supply tube (5). Slide
flue gas pipe (1) over the
O-ring (2) and below the
clamp (4), and tighten clamp
(4). Slide combustion air
supply duct (5) onto the
connecting piece (6) and
secure with clamp (7).
Assembly of wall cowl
Fig. E:
Choose a wall which
is as straight as possible
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 exhaust duct (1) so
that winding touches wind-
ing, 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).
Assembly of the
roof cowl
Fig. F:
Select a part of the
roof which is as straight as
possible and which is well
exposed to wind from all di-
rections. Drill an opening of
83 mm diameter at a center
distance of at least 65 mm
to the side walls (pack wood
into any hol low spaces in the
area of the cowl opening).
Sealing is carried out with
the enclosed rubber seal (20)
without further sealing
compound.
Slide rubber seal (20) on the
cowl part (21). Pass cowl
from above through the roof
and secure with retention
ring (22).
Mount cowl cover (23) and
secure with two screws (24).
The exhaust out lets
(25) must be positioned
crosswise to the direction of
travel, the label
„FRONT“
(26) must be facing in the
direction of travel!
Slide clamp (7) over the
combustion air supply tube
(5). Press together end of ex-
haust duct (1) so that win ding
touches winding. Slide clamp
(4) onto connecting piece (28)
and engage. Slide flue gas
pipe (1) over the O-ring (27)
and below the clamp (4), and
tighten clamp (4). Slide com-
bustion air supply duct (5) on-
to the connecting piece (29)
and secure with clamp (7).
Fasten cowl double duct
to the wall with at least
3 clamps ZRS (17).
Fastening the
appliance
The heater should be
firmly secured to the
vehicle in order to prevent
damage to the gas sys-
tem caused by movement
while driving!
This can be done by screw-
ing the heater to the floor us-
ing all three of the provided
B 5.5 x 25 screws or, should
this prove to be unsuitable,
by providing a load-bearing
surface beforehand (such as
plywood glued to the floor)
to which the heater can be
screwed.
Warm air distri bu tion
and circulating air
return
Heating air intake vents must
be arranged in such a way
that under normal operating
conditions exhaust gas from
the vehicle engine and heater
appliance cannot enter the
inside of the vehicle. 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, 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 or from
the vicinity of the exhaust
or the exhaust outlet of the
heater.)
Warm air distribution
Most of the warm air is led
into the floor area of the liv-
ing compartment via flexible
warm air ducts.
The 4 connecting pieces on
the unit are designed for the
65 mm diameter ÜR duct
(Part no. 40230-00). Only
pressure-proof air ducts that
comply with the Truma qual-
ity standard must be used.
Other ducts that do not meet
our quality standard (particu-
larly with regard to crown
pressure resistance, ducts
diameter and number of
grooves) must not be used.
Trumatic C 6002:
In order to prevent heat
accumulation when
using the Trumatic C 6002,
all 4 warm air connecting
pieces must be attached.
The cross-section of the
hot air pipes must not be
reduced by pipe connections
or the like.
If an EN end outlet that
can be closed off is in-
stalled in one of the Trumatic
C 6002 warm air ducts (e.g.
in the bathroom), a second
outlet that cannot be closed
off must be installed in the
warm air duct.
Trumatic C 4002:
All
four
or just three of the
warm air outlets of the
Trumatic C 4002 may be oc-
cupied (for the best possible
warm air distribution Truma
recommends that you should
always use all four warm air
outlets!). The unassigned
hot air outlet is closed off by
means of the closure cover
VD (Part no. 40353-01).
When 4 warm air out-
lets are being used,
an EN end piece that can
be closed off may only be
installed in
one
Trumatic
C 4002 warm air duct. If just
3 warm air outlets are being
used, it must be noted that a
second nozzle that cannot be
closed off must be installed
in the warm air duct if an end
piece that can be closed off
is being used (e.g. in the
bathroom).
The warm air system is de-
signed for each type of vehi-
cle individually, on a modular
basis. There is an exten-
sive accessories program
available (refer here to our
brochure). You can obtain
diagrams free of charge from
the Truma Service Centre,
