Exhaust duct
With the Trumatic E 2400 E only use the Truma exhaust duct
AA 24 (part no. 39420-00) for the installation with wall cowl
and the combustion air supply duct ZR 24 (part no. 39440-
00) as the appliance has only been tested and approved with
these ducts.
A new O-ring must always be installed after disman-
tling the exhaust duct!
Permissible duct lengths
1. Interior installation with wall cowl (refer to installation
variant 1, page 2):
– Duct lengths of up to max. 70 cm can be routed as as-
cending duct in any way required, or descending by max.
30 cm.
– Duct lengths from 70 cm to max. 150 cm must be rout-
ed as ascending duct with an ascending angle of min. 45°.
2. Under-floor assembly with wall cowl (refer to installation
variant 2, page 2):
Cowl double duct length max. 70 cm, routed as ascend-
ing duct in any way required or descending by up to 30 cm.
Interior installation using the wall cowl kit
Refer to installation variant, Fig 1 (page 2).
Assembly of wall cowl
Assemble wall cowl on a surface which is as flat as possible
and which is exposed to wind from all directions. Drill an
opening (8) measuring 70 mm in diameter (pack wood into
hollow spaces in the area of the cowl opening). Use the pro-
vided rubber seal (10) for sealing. In the event of structured
surfaces, coat with plastic body sealant – do not use silicone.
In the event of a greater wall thickness, first connect the
exhaust double duct to the cowl from the outside.
Slide rubber seal (10) and clamp (4) onto the cowl inner part (11).
Coat serrated connection fitting (9) with plastic body sealant
– do not use silicone! – and slide over combustion air supply
duct (5).

Double cowl duct connection to the
heating appliance
Press end of ex haust duct (1) together so that winding touch-
es winding. Slide clamp (4) over exhaust duct (1). Slide ex-
haust duct over O-ring on the connection fitting (2) up to the
collar (3). Attach with clamp (4) in such a way that the knurled
edge of the clamp encloses the collar. Fasten combustion air
supply duct (5) on the connection fitting (6) using clamp (7).
Always install a new O-ring following any dis-assembly!
Under-floor assembly with wall cowl kit
Refer to installation variant fig. 2 (page 2).
Install wall cowl on as flat a surface as possible on an outside
wall (vehicle apron, refer to "Interior installation using the wall
cowl kit").
If the wall cowl is fitted with fixing brackets or similar
below the floor, the vehicle floor must be airtight and
the waste gas must always be guided up to the side wall (see
„Choosing the installation place").
Fastening the appliance
Screw the 3 fastening strips (1, 2 + 3) to the appli-ance. Screw
appliance to vehicle floor with the strips 1 + 2. Fasten assem-
bly bracket (4 – special equipment Part. no. 39050-74000) to-
gether with strip (3) and screws (5). Place lock washers under
all screw heads and nuts.
