Air Top 2000
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.

To install the heater
The M6 nuts must be tightened with a torque of 6 Nm +1 Nm for installing
the Air Top 2000 heater.
The installation dimensions and space requirement for service access
are shown in the installation drawing (Figure 1). The specified horizontal
and axial angles must not be exceeded (Figure 2).
We recommend that petrol heaters be installed with the exhaust port
pointing vertically downwards.
NOTE:
Other installation positions may cause the burner to suffer increased
wear.

Seal
A seal (Figure 4) must be fitted between the heater and the vehicle body.
This seal must be replaced each time the heater is installed. The
support area for the heater foot must be flat. A special tool can be
purchased from the manufacturer to drill the holes and, if necessary,
smooth the support area. The seal can compensate for unevenness of
max. 1 mm.
