Disclosed is an apparatus for safely and effectively facilitating the ignition of logs positioned on a grate within a fireplace. It includes an elongated open top container and a base for support. The open top of the container maintains a flame sustained by the combustion of vaporized fuel. Once combustion of the fuel is initiated, the container walls defining this opening receive and conduct heat to the fuel reservoir to vaporize more fuel and thereby sustain combustion. Combustion may be initiated by a combustible wick. The upper section of the windward wall of the container slopes downwardly and outwardly from the opening at the top of the container and this surface cooperates with the surface formed by the bottom of the grate and its contents. Together, these surfaces restrict the natural draft underneath the grate producing somewhat of a venturi effect thereby increasing the velocity of the draft. Under the venturi influence, the draft trails the flame maintained at the top of the container beneath a greater depth of logs than it would otherwise contact, spreading the flame laterally as it stretches out. The combination of these effects maximizes the flane-to-log interface. The preferred configuration of the base allows the device to be prepared in an accessible position in front of the grate. The device may then be slid into position upon runners extended from the base.
