The Feuerhand Baby Special 276's cold air system works by supplying fresh air through a targeted tube system, providing the flame with oxygen while simultaneously protecting the glass from heat. For optimal light output, the wick should be adjusted so that the flame reaches a diameter of 1.5 to 2 cm, and any charred bits should be regularly trimmed. Additionally, the glass should be cleaned of soot after use, if necessary. The chimney can be pulled upwards to access the glass for cleaning.
