Air Top 2000

Metal lines must be used. These may not heat to more

than 110 °C should there be the possibility of contact

within the room interior. Protective devices against con-

tact may be fitted.

Should exhaust pipes be routed through rooms accom-

modating persons, these pipes shall be renewed after 10

years using genuine spare parts.

Combustion Air Inlet and Exhaust Outlet

During installations these ports for combustion air entry

and exhaust fume exit must be of such type, that a ball

with a diameter of 16 mm cannot be inserted.Electrical

lines, switch gear and control gear of the heater must be

located in the vehicle so that their proper function cannot

be impaired under normal operating conditions.

For the routing of fuel lines and the installation of addi-

tional fuel tanks §§ 45 and 46 of the StVZO are to be

adhered to.

The most important regulations are: Fuel lines are to be

designed in such a way that they remain unaffected by

torsional stresses in the vehicle, engine movement and

the like. They must be protected against mechanical

damage.

Fuel-carrying parts are to be protected against ex-

cessive heat and are to be arranged so that any dripping

or evaporating fuel can neither accumulate nor be ig-

nited by hot components or electrical equipment.

In busses, fuel lines and fuel tanks may be located

neither in the passenger area nor in the driver's compart-

ment. In these type of vehicles the fuel tanks must be lo-

cated such that they do not pose a direct hazard to the

exits in the event of a fire. Fuel supply must not be by

means of gravity or pressurization of the fuel tank.

Installation Rules for Webasto Fuel Tanks for the

Fuel Supply of Heaters in Vehicles

In busses the installation is not permitted in the pas-

senger or driver compartment.

The fuel fill neck must in no vehicle be located within any

of these compartments.

Fuel containers for carburettor fuel must not be located

immediately behind the front panelling of the vehicle.

They must be sparate from the engine so that even in

case of an accident the inflammation of fuel is unlikely to

be expected. This does not apply for towing vehicles

with an open cockpit.

The operational state of the heater, i.e. an indication "on"

or "off", must be easily and clearly visible.
