Approval, official regulations, general

1. For vehicles reg istered in West Germ any (subject to the road traffic

regulations StVZO), the heaters are a pproved by the Federal Motor
Vehicle Office and receive an official test symbol (131 L ~ S 133, D1
L A V S 146) indicate d on the name plate).
The year of first operation is a requirement of German approval not

representing a model number.

2.If the heater is installed in special-purpose vehicles (e. g. vehicles

transporting dangerous cargoes), the regulations applicable to such
vehicles must be observed.

3. The heater must not be operated in closed rooms, e.g. garages.

The heater must always be switched off when the petrol tank is to
be filled.

4. The heaters must be installed by a workshop approved by the

manufacturer and in compliance with the installation instructions.

5. The heaters may only be used for the purpose specified by the

manufacturer and in compliance with the operating instructions
supplied with every heater.
Operating the heater is not permitted where inflammable vapours or
dust can build up (e.g. near fuel, coal or sawdust stores, grain silos
etc.).
Spray cans and gas cartridges in the vehicle must be kept out of the
heating air current.

6. The proposed installations in the installation instructions are only
examples. Other installation locations are also permissible, provided
they comply with the general installation requirements: the
manufacturer should be consulted if necessary- In all other respects,
differences from the installation instructions, particularly with regard
to wiring (wiring diagrams), fuel supply, combustion air and exhaust
ducts, and use of operating and control elements not supplied by the
manufacturer, are only permissible with the written approval of the
manufacturer. Failing that, the manufacturer's warranty is null and
void for the entire heater system, as is the general operating permit.

7. Every combustion process generates exhaust gas, which has toxic
constituents. Because of this and the high temperatures generated,
the exhaust duct must comply without fail with the installation
instructions. Failure to comply with the instructions or operation of
the heater in closed rooms (garages) harbours the risk of poisoning.

8. When the heater or the heating system is damaged, an authorized
workshop must be called in to repair the damage in an expert
manner and using genuine spare parts.
Makeshift repairs (on one's own initiative) or the use of non-genuine
spare parts are dangerous, and therefore not permitted. When
carried out in cars, they invalidate the general design approval of the
heater and consequently the general permit of the vehicle.

9. The warranty conditions are set forth in the heater booklet given to
you by the after-sales service workshop when the heater is installed.
Only our warranty c onditions shall app ly.

Installation Instructions

The suggestions put forward in these installation instructions are only examples. Possibilities other than those illustrated (e. g.
with regard to the choice of installation location, means of running air) ar e a lso permissible, provided they meet the requirements
of the West German road traffic regulations (StVZO), and if necessary after consultation with the manufacturer.

Installing the heate r

The B 3 L and D 3 L heaters are suitable and approved for
installation in vehicle areas used by passengers.
In the case of installation in passe nger a re as, the exha u st,
combustion air and fuel lines in these areas must no t have
any detachable connections and must be splash-water-tight
at the penetrations to the outside.

For this reason, the heater must be mounted by its base on
an outside panel of the vehicle or on its floor, using the seal
seated on the base.

The factory plate must be clearly visible even when
installed.
If necessary a second fa ctory plate (duplicate) may b e
affixed, with the same information as the original, to a place
on the heater clearly visible after installation, or to a cover
placed in front of the heat er. A second plate is not if the
original is visible after removal of a cover without the
necessary, aid of tools.
