The device and its exhaust duct must always be installed so
that they are easy to access at all times for service work, and
are also easy to remove and install.
The distance between the heater and surrounding furniture
items or vehicle components must be at least 6 mm on all
sides.
Depending on the installation situation, additional space must
be provided for connections (gas, exhaust duct, warm air and
circulating air ducts).
The scope of delivery includes a second type plate (duplicate)
with removable bar code.
If the type plate on the heater is not visible after the heater
has been installed, the second type plate (duplicate) must be
affixed to the unit in a clearly visible location.
The duplicate must only be used in conjunction with the original.
In order to heat the vehicle evenly, the heater must be in-
stalled in a location in the vehicle that is as central in the ve-
hicle as possible, so that the air distribution ducts can be rout-
ed with approximately equal lengths. Appropriate openings
must be present in the installation compartment so that air
can be drawn in – see relevant sections concerning circulated
air intake and warm air distribution.
The operation of important vehicle components must not be
adversely affected.
In order to prevent damage to components inside the appli-
ance, no cables or water lines may be attached to the appli-
ance's housing.
The wall cowl must be attached so that there is no fuel tank
filler neck or fuel tank breather opening within 500 mm (R).
There must also be no living area ventilation openings or win-
dow openings within 300 mm (R).

If the cowl is being installed in the shaded area under-
neath or next to a window that will be opened, an elec-
tric window switch (part no. 34000-85800) must be installed.

Attaching the heater

Check whether the vehicle has a load-bearing floor, double
floor or false floor for securing the heater. If the floor is un-
suitable, create a load-bearing surface beforehand by gluing a
plywood board to the floor, for example.
Depending on the installation position, securely screw the
heater into place with the supplied fastening bows or brackets.

Screw the supplied PT screws for securing the mounting
bracket to the housing with a torque of 1.5 Nm. Securely
screw the appliance in place using the mounting brackets and
the supplied screws B 5.5 x 25.
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 duct

Only Truma exhaust duct AA 24 (part no. 39420-00) and
combustion air intake duct ZR24 (part no. 39440-00) may be
used for the Truma VarioHeat eco / Truma VarioHeat comfort
for installation with wall cowl, because the heaters have been
tested and approved only with these ducts.

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 12).
