ANNEX VII
REQUIREMENTS FOR COMBUSTION HEATERS AND THEIR
INSTALLATION
1. GENERAL REQUIREMENTS
1.7.1. A clearly visible tell-tale in the operator's field of view shall
inform when the combustion heater is switched on or off.
2. VEHICLE INSTALLATION REQUIREMENTS
2.1. Scope
2.1.1. Subject to paragraph 2.1.2, combustion heaters shall be
installed according to the requirements of this Annex.
2.1.2. Vehicles of category O having liquid fuel heaters are
deemed to comply with the requirements of this Annex.
2.2. Positioning of heater
2.2.1. 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.
2.2.2. 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.
2.2.3. In the case of M2 and M3 vehicles, the heater must not be
positioned in the passenger compartment. However, an
installation in an effectively sealed envelope which also complies
with the conditions in paragraph 2.2.2 may be used.
2.2.4. The label
(see chapter 7, "Identification plate")
referred to
in paragraph 1.4, or a duplicate, must be positioned so that it can
be easily read when the heater is installed in the vehicle.
2.2.5. Every reasonable precaution should be taken in positioning
the heater to minimise the risk of injury and damage to personal
property.
2.3. Fuel supply
2.3.1. The fuel filler must not be situated in the passenger
compartment and must be provided with an effective cap to
prevent fuel spillage
2.3.2. In the case of liquid fuel heaters, where a supply separate
to that of the vehicle is provided, the type of fuel and its filler point
must be clearly labelled.
2.3.3. A notice, indicating that the heater must be shut down
before refuelling, must be affixed to the fuelling point. In addition
a suitable instruction must be included in the manufacturer's
operating manual.
2.4. Exhaust system
2.4.1. The exhaust outlet must be located so as to prevent
emissions from entering the vehicle through ventilators, heated air
inlets or opening windows.
2.5. Combustion air inlet
2.5.1. The air for the combustion chamber of the heater must not
be drawn from the passenger compartment of the vehicle.
2.5.2. The air inlet must be so positioned or guarded that blocking
by rubbish or luggage is unlikely.
