Abstract: A modular linear fireplace gas burner system having a plurality of interconnectable pipe modules and one or more burner members of varying length, each said pipe module having a pipe segment, spuds, orifice mounting blocks and mounting brackets to retain one of more of the burner members, wherein the distance D(o) between adjacent spuds on each pipe segment is equal and for joined pipe segments the distance D(c) between the outermost spud of one pipe segment to the outermost spud of the other pipe segment is equal to D(o).
