Abstract
A gas burner assembly for a fireplace is shown. The assembly is operative to produce a flickering yellow flame pattern which closely resembles to that produced by a natural wood log fire, yet there is virtually no formation of carbon monoxide gas in the ignition. The assembly generally comprises four artificial logs arranged in a predetermined spaced relationship to a gas burner. The gas burner consists of a rectangular opened top casing having distribution means for emitting a gas and air mixture through its top. The artificial log comprises a flexible metal tube wrapped with a ceramic fibre blanked which is impregnated with a colloidal compound and thermally cured. The surface of the log is textured and painted to simulate the appearance of a natural wood log. Flame deflectors are provided either above or in the burner to baffle direct flame impingement on the logs so that the flames rise to a relatively high level above the logs to provide a full visibility of the flame in the fireplace.
