Exhaust Duct; Permissible Duct Lengths; Interior Installation Using The Wall Cowl Kit; Assembly Of Wall Cowl - Truma Trumatic E 2400 Gebrauchsanweisung

Cowls must always be fitted to prevent any waste gases en-
tering the inside of the vehicle. The waste gas must always be
guided to at least a side wall.
The wall cowl must be at-
tached so that no tank sup-
ports or tank ventilation
openings are found within
500 mm (R). In addition, no
air discharge apertures for the
living area or window open-
ings may be located with
300 mm (R) of it.
When fitting the cowl
within the marked area
below or next to a window
that must be open, an
electrical window switch
(part no. 34000-85800) must
be installed. The gas unit must
automatically switch itself off
using the Truma automatic
shut-off facility if the window
is opened (Accessories,
part no. 39050-00800).

Exhaust duct

With the Trumatic E 2400 only use the Truma exhaust duct
AA 24 (part no. 39420-00) for the installation with wall cowl,
and for boats use the Truma stainless steel exhaust duct
AEM 24 (part no. 39430-00) 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 dismantling
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
ascending duct in any way required, or descending by
max. 30 cm.
– Duct lengths from 70 cm to max. 150 cm must be
routed as ascending duct with an ascending angle of
min. 45°.

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).

300 mm
Press end of ex-haust duct (1) together so that winding
touches winding, slide over the O-ring (2a) on the connection
fitting (2) up to the collar (3 – cowl bend pointing upward) and
tighten clamp (4) in such a way that the knurled edge of the
clamp encloses the collar.
Coat serrated connection fitting (9) with plastic body seal-
ant – do not use silicone! – and slide over combustion air sup-
ply duct (5).
Fasten cowl inner part (11) with 3 screws (12 – observe instal-
lation position! The Truma lettering must be at the bottom).
Mount cowl outer part (13) and screw on with 2 screws (14).

Fastening the appliance

Depending on the installation position, bolt on the appliance
using fastening strap (a) or mounting brackets (b). Fasten
exhaust double duct to the wall using duct clamp ZR 24 (c), if
necessary (parts to be found in enclosed kit).
