Assembly of the roof
cowl
Fig. G: Select a part of the
roof which is as straight as
possible and which is well
exposed to wind from all
directions. 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
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).
Attention: The exhaust
outlets (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
exhaust 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). Engage 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
disassembly.

Fastening the
appliance
Bring appliance into
installation position and bolt
to the floor using the 3
fastening bolts.
If necessary, fasten
attachment strap at the top,
on the appliance, and bolt to
a stable furniture bracket.

Warm air distribution
and circulating air
return
Warm air distribution
The warm air system is
designed for each type of
vehicle 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
optimal installation
suggestions for warm air
systems in all current-type
caravans and mobile homes.
In the Trumatic C 6000 the
duct UR with 65 mm
diameter (Art. no. 40230-
00) must be connected at
all 4 warm air outlets.
In the Trumatic C 3400
either all four or just three
warm air outlets can be _
used. However, the duct UR
65 mm diameter with
several air outlets, must be
connected to at least one
warm air outlet on each
side. Close the warm air
outlets not being used with
caps VD (Art. no. 40352-
00).
Note: By using the 72 mm
diameter VR duct up to the
respective first air outlet,
the amount of noise is
reduced. For connecting this
duct, first remove the
reducing sleeve from the air
outlet connection fitting.
Circulating air return
The circulating air is sucked
back into the appliance,
either directly via an approx.
150 cm? opening (in the
C 6000) or 100 cm?
opening (in the C 3400)
from the living area into the
installation area or via
several smaller openings
with the same overall
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
connection fitting on the
appliance is not to be
shortened or bent.
Prior to connecting the
appliance 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 removed again for
servicing.
Keep the number of parting
connections in the gas
supply line in rooms
frequented by people to a
technically feasible
minimum.
In Germany the gas system
must comply with the
DVGW form G 607 or 608.
In other countries always
observe the respectively
valid technical and
administrative regulations.

Water connection
For the connection at the
water heater and the
electrical safety/drain valve
use hoses with a 10 mm
inside diameter.
Attention: Route water
hoses as short as possible
and free of kinks. All hose
connections must be
secured with hose clamps
(also cold water hoses!)
The thermal expansion of
the water can cause
pressures of up to 3.5 bar
before the overpressure
safety device in the
safety/drain valve reacts
(also in submergible pumps).
For fastening the hoses to
the wall or floor we
recommend using the hose
clips (Art. no. 40710-00),
which also permit frost-
proof routing of water hoses
on the hot air distributor
pipes of the heater.
Attention: Route all water
lines in descending manner
to the safety/drain valve so
that they can be completely
drained if there is a risk of
frost!
Installation of the
electrical safety/drain
valve
Fig. E: Install the valve (34)
in the direct vicinity of the
appliance in the heated area,
at a place which is easily
accessible to the user. Drill
an opening of 18 mm
diameter and pass through
discharge socket with hose.
Fasten valve with 2 screws.
The draining is to be directly
to the outside.
Routing of water
pipes
Fig. E: Connect the cold
water supply (33) to the
safety/drain valve (34). The
direction of flow is of no
significance.
With submergible pumps
install the Truma non-return
valve (35) between the
pump and the first branch
(arrow indicates flow
direction). This is not
necessary with pressure
pumps which already have a
non-return valve installed.
Provide hose connection
(36) for cold water supply
between safety/drain valve
and supply on water heater.
Route the hot water supply
line (37) from the elbow
connection with integrated
vent valve (38) to the hot
water consumers. The
elbow connection (38) must
be pointing downward and
can be swivelled to both
sides by max. 60°. Route
the 11 mm diameter hose
(40) from the nozzle of the
vent valve (39) to the
outside, do not make the
radius in the upper bend
smaller than 40 mm.
