refuelling, must be affixed to the fuelling point. In addition a suitable

instruction must be included in the manufacturer's operating manual.

be drawn from a clean area not likely to be contaminated by exhaust

fumes emitted either by the propulsion engine, the combustion heater or

any other vehicle source.
