DISCUSSION The Mechanical Code of the City of Fort Worth (Ordinance No. 8907, as amended) regulates the installation of heating, ventilation, air conditioning, and refri- yeration (HVACR) systems. The Mechanical Code is modeled from the Uniform Mechanical Code published by the International Conference of Building Officials (ICBO). Ordinance No. 8907 adopted the 1982 edition of the Uniform Mechanical Code with certain local amend- ments. The U.M.C. is updated every three years, and the Mechanical Board with the City staff reviews each new edition. The 1985 edition of the U.M.C. has been reviewed to determine what changes should be incorporated into the Fort Worth Mechanical Code. For the most part, the changes are editorial but some changes involve new materials and products being anufactured as high energy efficient equipment. To keep the Fort Worth Code up o date with the new products, some of the 1985 U.M.C. changes are necessary. City staff recommends that these changes be incorporated into the Mechanical Code by amending Ordinance No. 8907 rather than adopting the 1985 U.M.C. The Mechanical Board of Appeals has reviewed these changes and recommends that hey be adopted.
