VEHICLE INSTALLATION REQUIREMENTS
Subject to paragraph 2.1.2 / 5.3.1.2 combustion heaters shall be installed
according to the requirements of this Annex. (Requirements from
2001/56/EG Annex VII 2.1.1 and ECE R122 Part I 5.3.1.1)
Vehicles of category O (i.e. trailers including semi-trailers) having liquid fuel

(Requirements from 2001/56/EG Annex VII 2.1.2 and ECE R122 Part I
5.3.1.2)
POSITIONING OF HEATER AND INSTALLATION LOCATION
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
contamination. (Requirements from 2001/56/EG Annex VII 2.2.1 and ECE
R122 Part I 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
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. (Requirements from 2001/56/EG Annex VII 2.2.2 and ECE R122 Part I
5.3.2.2)
In the case of M2 and M3 vehicles (i.e. power-driven buses having at least
four wheels and used for carriage of passengers), the heater must not be
positioned in the passenger compartment. However, an installation in an
effectively sealed envelope may be used. (Requirements from 2001/56/EG
