Any gaps betwecn the nailing flanges <br />and the traming should be saaled with nomcombustible insulation <br />or caulking. �nspect the fireplace joints for possible gaps caused <br />by shipping or rnishandling during installation. These should be <br />sealed with non�com6us�ible materiais. If [he fireplace is nount- <br />ed on a raised platform, insulate below the platform to prevent <br />ihe entry of cold air through the fireplace bottom by means of <br />conduction. The above steps are important, esper.ially if the <br />fireplace is instal�ed in cold weather climate.
