Air Parking Heater Introduction
Arrangement of the Heater
– 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 fire-proof materials or heat plates are used.
– The heater must not be mounted in the passenger compartment of vehicles in class M2 and M3 .
But a heater in a hermetically sealed enclosure which otherwise complies with the conditions stated above may be used.
– 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.
Fuel Supply
– The fuel intake connection must not be located in the passenger compartment and must be sealed with a properly closing lid to prevent any fuel leaks.
– 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 connection 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.
