Securing The Device; Exhaust Gas Removal; Installing The Wall Cowl - Truma Combi E CP plus ready Einbauanweisung

Securing the device

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 heater to vehicle floor, double 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 alu-
minium feet (a) and selectively 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 removal

Only Truma exhaust duct AA 3 (part no. 39320-00), combus-
tion air intake duct ZR (part no. 39580-00) and the supplied
clamps (part no. 34020-14200) may be used. The appliance is
only tested and approved with these components.
Do not crush or kink ducts during installation.
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
installed rising.

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 silicon!
b
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).
