Securing the appliance
Check whether the vehicle has a load-bearing floor, double
floor or false floor for securing the heater. If the floor is unsuit-
able, create a load-bearing surface beforehand by gluing a
plywood board to the floor, for example.
Screw the heater to vehicle floor, double floor or false floor us-
ing four B 5.5 x 25 screws (included in scope of delivery). De-
pending on the installation situation, it may also be possible
to secure the heater with three screws. In this case, always
screw the aluminiumfeet (a) and optionally one of the plastic
feet (b) to the vehicle floor.

The heater must be screwed to the floor, double
floor or false floor of the vehicle in order to pre-
vent the gas system from becoming damaged because
of movement while driving!
Exhaust gas system
Fire hazard from overheating and/or danger of suffoca-
tion from exhaust fumes if installed incorrectly or if
parts other than original Truma parts are used for the exhaust
gas system.
– Use only original Truma parts for the exhaust gas system.
– Follow the installation instructions when installing the ex-
haust gas system.
Only the Truma exhaust duct AA 3 (part no. 39320-00), com-
bustion air intake duct ZR 80 (part no. 39580-00) and the sup-
plied clamps (part no. 34020-14200) may be used. The appli-
ance is only tested and approved with these components.
Do not crush or kink ducts during installation.
The distance between the exhaust gas system and adja-
cent heat-sensitive parts must be at least 10 mm.
The roof cowl is available as an accessory to the heater
– the roof cowl comes with installation instructions.
Installing the wall cowl
Permissible duct lengths
The length information relates to the combustion 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 in-
stalled rising.

Figure 6
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 the rubber seal (8 –
smooth side towards cowl, seal-
ing lips towards wall)
onto the cowl inner part (9).
Compress the beginning of the exhaust duct (1) (approx. 2 cm
thereof) so that the coils are lying against each other.
Slide the clamp (2 – claws facing the cowl) over the
exhaust duct (1).
Slide the exhaust duct (1) onto connection as far as it will go
(11 – bend facing upwards).
Slide the clamp (2) as far as it will go (end position must be
between claws of clamp) and screw in place.
Slide the combustion air intake duct (5) onto the serrated con-
nection (12).
Attach the cowl inner part (9) with six screws (13), fit the
cowl outer part (14) and screw on with two screws (15)
(screws B 3.5 x 25, included with delivery).
Use the clamp (7) to attach the combustion air intake duct to
the connection (12) from inside and (if the length is greater
than 60 cm) attach to the wall with at least one clamp ZRS
(16 – part no. 39590-00).
