Abstract
Abstract A log lighter includes support structure for transversely extending front and rear logs (which may function as log rests), together with a transversely elongated gas burner carried by the support structure; flame chute structure extending generally frontwardly of the burner; and the burner having ports located in such combustible gas release relation to the chute structure as to produce full flame projection channeled for forward flow under the front log and to rise at the front of that log, as well as additional flame rising upwardly between the front and rear logs. Other flame chute structure may also produce flame projection below the rearlog to rise at the rear of that log, and a flame deflector may extend lengthwise over the burner and in predetermined relation to the chute structure.
