3 Installation location and installation position
Body sections and any other components in the vicinity of the heater must
be protected from excessive heat and the possibility of fuel or oil contami-
nation. (Requirement from 2001/56/EC, Appendix VII, Point 2.2.1. and ECE
R122, Point 5.3.2.1.).
The combustion heater shall not constitute a risk of fire, even in the case of
overheating. This requirement shall be deemed to be fulfilled if the instal-
lation 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 2001/56/EC, Appendix VII, Point 2.2.2. and ECE R122, Point 5.3.2.2.).
The heater is preferably installed in the engine compartment, i.e. in the area
between the wheel well and the front bumper.
Installation should be carried out as low as possible to ensure automatic
bleeding of the heater and circulation pump.
The openings of the heat exchanger may not face downward in
any installation position.
Fig. 1 shows the permissible installation position of the heater.
For the position of the heat exchanger opening of the heater, see fig. 2.
