– In heaters for liquid fuel where the heater fuel is
separate from the vehicle fuel, the type of fuel and
intake connection must be clearly identified.
– A warning sign is to be fixed to the intake connec-
tion indicating that the heater must be switched off
before refuelling.
• Exhaust system
– The exhaust outlet must be arranged so as to
prevent any penetration of exhaust fumes into the
vehicle interior through the ventilation system, warm
air intakes or open windows.
• Combustion air intake
– The air for the heater’s combustion chamber must
not be sucked in from the vehicle’s passenger compartment.
– The air intake must be arranged or protected in such
a way that it cannot be blocked by other objects.
• Hot air intake
– The heater’s air supply must consist of fresh air or
circulated air and must be sucked in from a clean
area, which cannot be contaminated by exhaust
fumes from the engine, the combustion heater or
any other source in the vehicle.
– The intake pipe must be protected by a grid or other
suitable means.
• Hot air outlet
– The hot air pipes within the vehicle must be ar-
ranged or protected in such a way that there is no
risk of injury or damage if they are touched.
– The air outlet must be arranged or protected in such
a way that it cannot be blocked by any objects.
