If the cowl is being installed directly underneath a window
that will be opened, installation of an electric
window switch (part no. 34000-85800) is mandatory.
Information about roof windows
In the case of roof windows (pop-out), the cowl top needs to
protrude at least 10 cm above the opened window. If the cowl is
next to the window, steps must be taken to ensure that, depending
on where it is installed (opened on the right or left), no exhaust air
can enter the open window (e.g. via wind) and that the cowl has a
good supply of incoming air.

Gas Installations, for location
requirements of the flue terminal.
Securing the device
Check whether the vehicle has a load-bearing floor or false floor for
securing the heater. If the floor is unsuitable, create a load-bearing
surface beforehand by gluing a plywood board to the floor, for
example.
Screw
heater to vehicle floor or false floor using four B 5.5 x 25
screws (included in scope of delivery). Depending on the situation, it
may be possible to secure the heater with three screws; in this case,
always screw aluminum feet (a) and selectively one of the plastic
feet (b) to the vehicle floor.
Fig. 13
The heater must be screwed to the floor of the vehicle or
the false floor in order to prevent the
gas system from becoming damaged because of movement while
driving!
Exhaust gas removal
Only Truma exhaust duct AA 3 (part no. 39320-00) and combustion
air infeed ZR (part no. 39580-00) may be used for the Truma Combi
2 E / 4 E (Australia) heater because the unit was tested and
approved only with these ducts.
Do not crush or kink these ducts during installation.
The roof cowl is available as an accessory to the heating
device
–
assembly instructions are enclosed with the delivery.
Installing the wall cowl
Permissible duct lengths
The length specific ations refer to the combusti on air intake duct.
Ducts with a length of at least 60 cm to a maximum of 100 cm can
be routed with any amount of rising for the wall cowl, or with a
maximum fall of 20 cm.
Duct lengths from 100 cm to max. 200 cm may only be installed
rising.
Fig. 14
The ducts must be cut to length so that they protrude from the hole
for the cowl after installation. The exhaust duct (1) must be 10 %
longer than the combustion air intake duct (5). This avoids exhaust
duct expansion and tensile load.

Installing the wall cowl
Install wall cowl (arrow pointing up) on an even surface around
which wind can flow from all sides. Drill opening with a diameter of
83 mm (duct hole must be lined with wood in cavities). Seal with
provided rubber seal (8). Use flexible body sealant on textured
surfaces
–
do not use silicone!
Before pushing the exhaust double duct through the hole, slide
clamp (7) over duct.
Slide rubber seal (8
–
smooth side towards cowl, sealing lips
towards wall)
onto inner part of cowl (9).
Compress beginning of exhaust duct (1) (approx. 2 cm thereof) so
that the coils are lying against each other.
Slide clip (2 - claws facing cowl) over exhaust duct (1).
Slide exhaust duct (1) onto connection as far as it will go (11
–
bend facing upwards).
Slide on clip (2) as far as it will go (end position must be between
claws of clip) and screw in place.
Slide combustion air intake duct (5) onto toothed connecting piece
(12).
Attach cowl inner part (9) with six screws (13), fit outer part of
cowl (14) and screw on with two screws (15) (screws B 3.5 x 25,
included with delivery).
Use clip (7) to attach combustion air intake duct to connection (12)
from inside and (if length greater than 60 cm) attach to wall with at
least one clip ZRS (16 - part no. 39590-00).
