COLEMAN <CLN> SEES 1ST QTR CHARGE Coleman Co said it expects a first-quarter charge against earnings of 1.6 mln dlrs, or 23 cts a share, as a result of its voluntary program to replace condensing heat exchangers in its early Model 90 series high-efficiency residential gas furnaces. The company said extensive testing indicates a problem found in the furnaces is not safety related. Coleman said it noted an increasing number of heat exchangers in certain furnaces made from March 1984 through December 1985 were returned because of corrosion.
