Parts of the structure and other components near the heater
must be protected from excess heat exposure and possible
contamination from fuel or oil.
The heater must not pose a fire hazard even when it
overheats.
– This requirement is deemed to be fulfilled when
adequate clearance to all parts is observed during
installation, sufficient ventilation is provided and fireproof
materials or heat plates are used.
The heater must not be located in the passenger compartment.
A unit may however be used in a hermetically sealed housing
which also corresponds to the conditions stated above.
The factory nameplate or duplicate must be affixed so that it
can still be easily read when the heater is installed in the
vehicle.
All appropriate precautions must be taken when
arranging the heater to minimise the risk of injuries
to persons or damage to other property.
