Regulations concerning installation in the vehicle
Scope

Subject to differing stipulations in the following section,
combustion heaters must be installed according to the regulations
5.3 of ECE-R122.

It is assumed that Class O vehicles with heaters for liquid fuel
conform to the regulations 5.3 of ECE-R122.
Arrangement of the heater
 Parts of the structure and other components near the heater must
be protected from excessive heat exposure and possible fuel or oil
contamination.
 The combustion heater shall not constitute a risk of fire, even in
the case of overheating. This requirement shall be deemed to be
met if the installation ensures an adequate distance to all parts
and suitable ventilation, by the use of fire resistant materials or by
the use of heat shields.
 Do not install the heater in the passenger compartment of class
M
2
and M
3
vehicles. However, a heater in a hermetically sealed
enclosure which also complies with the aforementioned conditions
may be used.
 Attach the nameplate, or a duplicate, so that it can be easily read
when the heater is installed in the vehicle.
 Take every reasonable precaution in positioning the heater to
minimize the risk of injury or damage to items carried in the
vehicle.
Fuel supply
 If a separate fuel tank is used, the fuel filler neck may not be
located in the passenger compartment and must be fitted with a
properly closing cap to prevent any fuel leaks.
 In heaters for liquid fuel where the heater fuel supply is separate
from the vehicle fuel supply, the type of fuel and filler neck must
be clearly marked.
 Attach a notice to the filler neck informing that the heater must be
switched off before refuelling.
Exhaust system
The exhaust outlet must be arranged so as to prevent any penetration
of exhaust fumes into the vehicle interior through the ventilation
system, warm air intakes or open windows.
Combustion air intake

Do not draw the air for the combustion chamber of the heater from
the passenger compartment of the vehicle.

Position or protect the air inlet so that it cannot be blocked by
objects.
Automatic control of the heating system
If the engine fails, the heating system must be switched off
automatically and the fuel supply stopped within 5 seconds. The
heater may remain in operation if a manual device has already been
activated.
Notes

The heater is not approved for installation in the driver's cab
or passenger compartment of Class M
1
vehicles (vehicles for
passenger transport / cars) and N vehicles (vehicles for the
transport of goods).

Compliance with the statutory regulations, the additional
regulations and the safety instructions is prerequisite for guarantee
and liability claims.
 Failure to comply with the statutory regulations and safety
instructions and incorrect repairs, even if original spare parts are
used, make the guarantee null and void and exclude any liability
whatsoever of Eberspächer Climate Control Systems GmbH & Co.
KG.
 The statutory regulations are binding and must also be observed in
countries which do not have any special regulations.
 Subsequent installation of this heater must comply with these
installation instructions.
 When installing the heater in vehicles not subject to the German
Road Traffic Licensing Regulations (StVZO), the respective specially
valid regulations and installation instructions must be observed.
 Installation of the heater in special vehicles must comply with the
regulations applying to such vehicles.
 Further installation requirements are printed in the relevant
sections of these installation instructions.
