1 Introduction
Thermo Top Z/C
102
The heater must not be installed in the passenger or driver
compartments of vehicles.
At filling stations and fuel depots the heater must be
switched off as there is a potential danger of explosion.
Due to the danger of poisoning and suffocation the heater
must not be operated, not even with timer or under remote
radio control (Telestart), in enclosed areas such as
garages or workshops not equipped with an exhaust
venting facility.
In the vicinity of the heater a temperature of 120 °C
(storage temperature) must not be exceeded under any
circumstances (e.g. during body paint work). Excessive
temperatures may cause permanent damage to the
electronics.
1.5 Legal Provisions for Installation
For testing the heater in accordance with § 19, 20, or 21
of the StVZO the following regulations are to be observed
in particular (§ 22 a StVZO):
Testing is performed upon presentation of the operating
and installation instructions of the manufacturer. The year
of the initial operation must be durably marked on the
heater identification plate by the installing person.
Extracting combustion air from the vehicle interior is
prohibited.
The exhaust line outlet is to point downwards or to the
side, or in case of exhaust venting below the vehicle floor,
to be located at the nearest possible location of the
vehicle's or cockpit side or rear end.
Exhaust lines must be routed so that exhaust fumes are
unlikely to penetrate into the vehicle's interior. The
function of any part of the vehicle essential for operation
must not be impaired. Accumulations of condensate in the
exhaust line must be directly drained. A drain hole may be
provided as required.
The openings of the combustion air inlet and the exhaust
outlet must not allow a ball of 16 mm in diameter to be
inserted.
Electrical lines and switching 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
additional 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 excessive heat and
are to be arranged so that any dripping or evaporating
fuel can neither accumulate nor be ignited by hot
components or electrical equipment.
• the heater must not be located in rooms
accommodating persons.
• the heater mode of operation - at least "on" or "off" -
must be clearly visible.
The obligation to apply for a new "Operating License"
(with expertise) after heater installation does not
exist, if the installation meets entirely the
requirements of an installation instruction, for which
a special supplement exists for the "Design General
Approval". The "Design General Approval" and the
"Operating License" documentation are to be kept
with the vehicle.
• Non-approved installations will void the heater's
marks of conformity and thus the vehicle's permit of
operation. The same applies to unskilled repairs or
repairs not using original spare parts.
