Installation Instructions

Legal Provisions for Installation

For testing the heater in accordance with §§ 19, 20 or 21
StVZO (German Road Licensing Regulations) the follow-
ing regulations are primarily to be observed (§ 22 a
StVZO):
NOTE:
These provisions are binding within the scope of the
StVZO and should also be observed in countries
where no special regulations are in effect!
Within the scope of the StVZO (German Road Licensing
Regulations) "General Design Certifications" have been
granted by the Federal Office for Motor Traffic for the Air
Top 3500/5000 air heaters with the following design appro-
val numbers:
~ S 305 Air Top 3500 B
~ S 306 Air Top 3500 D
~ S 304 Air Top 5000 B
~ S 303 Air Top 5000 D
The installation of the heaters must be performed in ac-
cordance with these Installation Instructions. The installa-
tion must be checked
a) upon the homologation of the vehicles in accordance
with § 20 StVZO
b) upon any individual test in accordance with
§ 21 StVZO, or
c) upon any examination in accordance with
§ 19 StVZO by a registered expert or examiner for
motor traffic, an expert for automotive vehicles,
or any other authorised official, in accordance with
paragraph 7.4 a of Appendix VIII to the StVZO
and in the case of item c) the proper installation must be
certified on the approval certificate contained on the de-
sign certification stating the following:
- vehicle manufacturer
- vehicle type and
- vehicle identification number
The effectiveness of the design certification (homologa-
tion) is dependent on this certificate. The approval certifica-
tion is to be kept in the vehicle.
The year of the initial operation must be durably marked
on the type plate of the heater by the installer by removing
the years that do not apply.
The heat exchanger of the air heater is not to be used
for longer than ten years and must thereafter be re-
placed by the manufacturer or one of its authorised
dealers with a genuine replacement part.
If exhaust pipes lead through passenger areas, these
pipes must also be replaced with genuine replacement
parts after ten years.
Whenever the heater is removed it is imperative that
the gasket located underneath be replaced.
The heaters are approved for heating the passenger com-
partment and the driver's cabin, not however, the cargo
space for the transport of hazardous materials.
When using the heater in special vehicles (e.g. "TRS" ve-
hicles for the transport of hazardous materials) or in ve-
hicles not subject to StVZO regulations (e.g. ships) all regu-
lations that may be locally applicable are to be complied
with.

When installing the heater in ve-
hicles for the transport of hazardous materials the require-
ments laid down in TRS 002 and TRS 003 (Technical Gui-
delines relating to the ordinance of transporting hazardous
materials on the road) must be fulfilled in addition to those
of the StVZO.
"Heating air system":
Heating air intake openings must
be so arranged that the possibility of exhaust fumes from
the vehicle engine and the heater being drawn in is remote
under normal operating conditions.

Extracting the combustion air from the interior of the ve-
hicle is not permissible.
"Combustion air pipe: The combustion air required
must be drawn in from the outside of the vehicle.
Inside passenger areas the combustion air lines are per-
mitted to have a maximum of four joints and must be pro-
vided with a splash-proof opening leading through the out-
side wall. These joints must be so sealed that a total leak-
age rate of 200 l/h at an overpressure of 0.5 mbar is not ex-
ceeded.
The pipe including lead-through, joints, material and type
of construction must be specified in the installation instruc-
tions.
Mounting and removal of the pipe must be possible with
tools only, the pipe must be protected against damage and
be permanently vibration-proof.
"Exhaust gas pipe":
The heaters must be so designed
that the exhaust fumes are discharged to the atmosphere.
Exhaust pipes must be so routed that the possibility of ex-
haust gases penetrating the interior of the vehicle is
remote. The functioning of any parts of the vehicle essen-
tial for its operation must not be impaired. Any condensate
or water that may have entered must not be able to collect
in the exhaust gas line. Drain holes are permissible; these
must discharge the liquid to the atmosphere via lines that
are leakproof in relation to the interior of the vehicle.
The discharge opening of the exhaust pipe is to point up-
ward, sideways or, in the case of routing the exhaust pipes
on the underside of the bottom of the vehicle, it must be po-
sitioned near the lateral or rear edge of the driver's cab or
vehicle.
Inside areas where people are present, exhaust pipes may
have a maximum of one joint, and their lead-through
through the outer wall/bottom of the vehicle must be
splash-proof. It is permissible to connect a drain pipe pro-
vided with a leak-proof metal joint to discharge the water
penetrated into the exhaust pipe. The drain pipe is to be
passed through the outside wall or the bottom of the ve-
