Abstract
A kerosene heater having a vertically oriented wick (4) which is movable to an upper position to be ignited, to a lowered position to be extinguished, and to any of a range of intermediate positions for continuous combustion, incorporates an apparatus (6A) operable by actuating a lever (6) to raise the wick to the upper position and initiate ignition and to lower the wick from that position, and an apparatus coupled thereto for automatically lowering the wick to a predetermined position within the combustion range after a predetermined time interval has elapsed following the start of igniting the wick. The danger of excessive flare-up of the wick flame after ignition is thereby eliminated, without the need for observation and control of the heater by the user.
