Air Top 2000 S
If the heater is installed in an installation box, it may be installed on the
exterior of the vehicle and operate in air circulation mode. The
installation box must be purchased from Webasto or its design must be
approved by Webasto.
The openings for the combustion air inlet port, the exhaust outlet port
and the fuel pipe must be sealed splashing water if the heater is installed
in the interior. The seal designed and supplied for this purpose must be
used (see Figure 4). This seal must be replaced each time the heater
is installed.

The M6 nuts must be tightened with a torque of 6 Nm +1 Nm for installing
the Air Top 2000 S heater.
The installation dimensions and space requirement for service access
are shown in the installation drawing (Figure 1). The specified horizontal

We recommend that petrol heaters be installed with the exhaust port
pointing vertically downwards.
