Abstract: Modular chimney components are arranged for interengaging relative to one another, wherein each component includes a base member having a support plate receiving four inner flanges at four corners of the support plate, with second outer flanges projecting upwardly of the inner flanges to mount a continuous mesh fence thereabout, wherein the mesh fence is arranged to receive a mortar layer thereon to an interior surface thereof, with the mortar layer projecting through the mesh fence securing a matrix of work plates continuously to an exterior surface of the fence. The modular components are arranged for interengagement relative to one another to provide for a chimney covering arrangement about a flue.
