Combustion air supply

Thermo 50
8 Combustion air supply
Under no circumstances may the combustion air be taken from areas
occupied by people. The combustion air intake opening must not point
in the direction of travel. It must be located so that it cannot become
clogged with dirt or snow and cannot suck in splashing water.
The combustion air intake line can be routed with several bends
(270° altogether, minimum bending radius 50 mm).
The maximum line length equals 1000 mm.
A combustion air intake line is required.
The combustion air intake must not be routed above the exhaust outlet.
If the heater is installed in a common installation space near the vehicle
tank, the combustion air must be taken in from the outside and the
exhaust gas discharged into the atmosphere. The openings must be
splash-proof.

A ventilation opening measuring at least 3 cm is required if the heater
is installed in an enclosed box. The size of the ventilation opening must
be increased subject to consultation with Webasto if the temperature in
the box exceeds the permitted ambient temperature of the heater
(see Technical data).
