Exhaust gas system

Fire hazard from overheating and/or danger of suffo-
cation 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 24 (part no. 39420-00), the
combustion air intake duct ZR 24 (part no. 39440-00) and the
supplied clamps ÜS (part no. 40241-01) may be used for the
appliance. The appliance is only tested and approved with
these components.
Possible risk of cut injuries from sharp edges on the ex-
haust duct. Wear protective gloves during installation.

Permissible duct lengths

Duct lengths of 30 cm up to max. 150 cm
(see page 2 for installation options)
Do not crush or kink ducts during installation.
Secure the ducts with a clamp (15) every 50 cm (Figure 13).

Installing the wall cowl

Fit wall cowl to a surface that is as flat as possible so that air
can flow around at all sides.
– Drill opening (8) with a diameter of 70 mm (duct hole must
be lined with wood in cavities).
– Seal with provided rubber seal (10). Use flexible body seal-
ant on textured surfaces – do not use silicone.
– Slide the rubber seal (10 – smooth side to the wall) and
clamp (4) onto the inner part of cowl (11).
– Before pushing the exhaust double duct through the hole,
slide clamp (7) over duct.

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.
– Compress the beginning of the exhaust duct (1) (approx.
2 cm thereof) so that the coils are lying against each other.

– Push the exhaust duct (1) over the O-ring (2a) and onto the
connection (2) as far as the collar (3) (the wall cowl angle
faces upwards).
– Position the clamp (4) so that the flanged rim of the clamp
is gripping the collar.
– Securely screw the clamp (4) into place (tightening torque
1 Nm).
Figure 14
– Secure the cowl inner part (11 / 16) with the screws (12)
(pay attention to the installation position – the Truma logo
must be at the bottom).
– Fit outer part of cowl (13) and screw it on with 2 screws (14).
– Slide the combustion air intake duct (5) onto serrated con-
nection (9) and secure with clamp (7) (3 Nm).
A new O-ring (2a) must be fitted after every removal.
Connecting the exhaust double duct to the
appliance
– Push the clamp (7) over the ducts.
– Compress the exhaust duct (1) at its beginning so that the
coils are lying against each other.
– Slide the clamp (4) over the exhaust duct (1).
– Slide the exhaust duct (1) over the O-ring (2a) on the con-
nection (2) as far as the collar (3).
– Hook in the clamp (4) and screw it securely into place, 1 Nm.
Slide the combustion air intake duct (5) onto the connec-
tion (6) and secure with the clamp (7), 3 Nm.

Warm air distribution

14
The heater routes the warm air either directly or via flexible
ducts in the floor living compartment (warm air distribution).
Fire hazard or risk of malfunction if installed incorrectly
or if parts other than original Truma parts are used for
the warm air distribution.
– Use only original Truma parts for the warm air distribu-
tion. The heater is only tested and approved with these
components.
– Follow the installation instructions when installing the
warm air distributor.
The warm air system for the heater is designed individually for
each vehicle type using the modular design principle. A wide
range of accessories is available from Truma for this purpose.
