Note:
By using the 72 mm
diameter VR duct up to the re-
spective first air outlet, the
amount of noise is reduced. For
connecting this duct, first re-
move the reducing sleeve from
the air outlet connection fitting.
Circulating air return
The circulating air is sucked in
again by the device, either
directly via an aperture mea-
suring about 150 cm
2
from
the living room to the instal-
lation room, or via several
smaller apertures with the
same surface area.

Gas connection
The gas supply line, diameter
8 mm, is connected to the
connection fitting with olive
couplings. Carefully hold in
place with a second wrench
when tightening!
Attention:
The gas connecti-
on fitting on the appliance is
not to be shortened or bent.
Prior to connecting the appli-
ance make sure that the gas
lines are free from dirt, chips
and such!
Route the pipes in such a way
that the appliance can be re-
moved again for servicing.
Keep the number of parting
connections in the gas supply
line in rooms frequented by
people to a technically feasi-
ble minimum. The gas system
must comply with the techni-
cal and administrative rules
and regulations of the respec-
tive country of destination.

Water connection
For operating the water
heater it is possible to use all
pressure pumps and sub-
mergible pumps up to 2.8 bar,
also all mixing taps with or
without electrical switch.
Fig. H:
When using immer-
sion pumps, a non-return
valve (33 - not included in the
scope of supply) must be fit-
ted between the pump and
the first branch point (arrow
points in direction of flow).
Fig. J:
When using pressure
pumps with high switching
hysteresis, hot water may
flow back through the cold
water tap. To prevent the
backflow, we recommend
that a non-return valve (34 -
not included in the scope of
supply) be fitted between the
outlet to the hot water tap
and the drain valve.

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 struc-
tured surfaces coat with plas-
tic 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) and
clamp (4) on the cowl inner
part (9). Press together end of
exhaust duct (1) so that wind-
ing touches winding, and
slide over O-ring (10) onto the
connection fitting (11) (bend
pointing up).
Engage clamp (4) with hole
on the upper pin (screw
pointing down) and tighten.
Slide combustion air intake
duct (5) on the serrated con-
nection 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 fit-
ting (12).
Fasten cowl double duct to
the wall with at least one
clamp ZRS (17).
Attention:
Always install a
new O-ring following any dis-
assembly.
5
Assembly of the
roof cowl
Fig. F:
Select a part of the
roof which is as straight as
possible and which is well ex-
posed to wind from all direc-
tions. Drill an opening of
83 mm diameter at a center
distance of at least 65 mm to
the side walls (pack hollow
cavities in the area of the
cowl opening with wood).
Sealing is carried out with the
enclosed rubber seal (20)
without further sealing com-
pound.
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).
Attention: The exhaust
outlets (25) must be posi-
tioned crosswise to the di-
rection of travel, the label
„FRONT“ (26) must be fac-
ing in the direction of trav-
el.
Slide clamp (7) over the ex-
haust gas double duct.
Press together end of exhaust
duct (1) so that winding
touches winding and slide
over the O-ring (27) onto the
connection fitting (28). En-
gage clamp (4) and tighten.
Slide combustion air intake
duct (5) onto the connection
fitting (29) and secure with
clamp (7).
Fasten cowl double duct to the
wall with at least 3 clamps
ZRS (17).
Attention:
Always install a
new O-ring following any dis-
assembly.

Fastening the
appliance
Bring appliance into installa-
tion position and, using the
three provided fastening bolts
B 5.5 x 25, ensure the appli-
ance is firmly connected to a
suitable base (sawn wooden
board, laminated wooden
battens or metal base).

Warm air distribu-
tion and circulating
air return
Warm air distribution
The warm air system is de-
signed for each type of vehi-
cle individually, on a modular
basis. There is an extensive
accessories program available
(refer here to our brochure).
You can obtain diagrams free
of charge from the Truma
Service Centre, showing opti-
mal installation suggestions
for warm air systems in all
current-type caravans and
mobile homes.
In the Trumatic C 6002 the
duct ÜR with 65 mm dia-
meter (Art.-no. 40230-00)
must be connected at all
4 warm air outlets.
With the Trumatic C 3402, all
four or only three of the hot
air outlets can be assigned.
The unassigned hot air outlet
is closed off by means of the
closure cover VD (Art.-no.
40352-00).
2
Exhaust duct
For the Trumatic C only use
the Truma exhaust duct AA-3
(Art.-no. 39320-00) or, for
boat installation, the Truma
stainless steel exhaust duct
AEM 3 (Art.-no. 39360-00)
and the combustion air supply
duct ZR (Art.-no. 39580-00),
as the appliance has only
been tested and approved
with these ducts.
Attention:
The length specifi-
cations refer to the combusti-
on air intake duct (Ref. no. 5).
Cut ducts to lengths so that
these project out of the open-
ing for the cowl during instal-
lation. Cut the exhaust duct
(1) so that it is 10 cm longer
(5 cm longer for shorter ex-
haust ducts measuring up to
70 cm). This avoids elonga-
tion and a tension load on the
exhaust duct.
Permissible duct
lengths
Fig. A:
For the wall cowl the
duct lengths can be routed
from min. 50 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. B:
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) over the exhaust
duct (1) and slide clamp (7)
over combustion air supply
duct (5). Slide exhaust duct
over the O-ring (2) onto the
connection fitting (3). Engage
clamp (4) and screw on. Slide
combustion air supply duct
(5) onto connection fitting (6)
and fasten with clamp (7).
Attention:
Always install a
new O-ring following any dis-
assembly.
