A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs an excess fuel containment compartment (24) which receives any excess fuel which might be fed to the fuel supply chamber (40) . The excess fuel causes a receptacle (20) in the compartment to move downwardly. Through a rod (30) and balance arm (18), such movement communicates with an automatic wick extinguisher (42) to extinguish the wick flame immediately in response to the excess fuel condition. Also the mechanism prevents re-ignition of the wick (54) until the danger of flareup is removed. This safety device also alerts the user of the liquid fuel burner to dangerous conditions by a mechanism comprising a highly visible warning gauge needle (34) . In addition, this safety device can be easily reset if accidentally triggered when overflow conditions do not exist, and the burner can be readily serviced and restored to operation should an excess fuel malfunction occur.
An apparatus for preventing flare-up in a liquid fuel burner of the type comprising a liquid fuel removable tank, a fuel chamber, and a combustion chamber having a wick, where said fuel chamber carries liquid fuel from said removable tank to said wick of said combustion chamber, comprising:
