Installing The Wall Cowl; Connecting The Exhaust Double Duct To The Device; Warm Air Distribution - Truma VarioHeat Series Einbauanweisung

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 silicon .
– 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).

– Secure the cowl inner part (11) with 3 screws (12) (pay at-
tention 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 device

– 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 con-
nection (6) and secure with the clamp (7) 3 Nm.

Warm air distribution

The heater routes the warm air either directly or via flexible
ducts in the floor living compartment (warm air distribution).
For the warm air distribution, use only pressure-safe ducts in
compliance with Truma quality requirements. Other ducts that
do not meet our quality standard (particularly crown pressure
resistance, duct diameter and number of grooves) must not
be used.
