Requirements for the installation location

Body sections and any other components in the vicinity of the
heater must be protected from excessive heat and the possi-
bility of fuel or oil contamination.
(Requirement from ECE-R 122, Point 5.3.2.1.).
The 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.
(Requirement from ECE-R 122, Point 5.3.2.2.).
In the case of M2 and M3 vehicles, the heater must not be
positioned in the passenger compartment. However, an in-
stallation in an effectively sealed envelope which also com-
plies with the conditions in paragraph 5.3.2.2. may be used.
(Requirement from ECE-R 122, Point 5.3.2.3.).
Every reasonable precaution should be taken in positioning
the heater to minimize the risk of injury and damage to per-
sonal property.
(Requirement from ECE-R 122, Point 5.3.2.5.).
