Factory piping installed, within HVAC equipment. 2. Piping at temperatures between 65°F and 120°F. 3. Piping installed under slabs, in basements, cellars or unventilated crawl .spaces with insulated walls in one and two- family dwellings. (b) Other Pipe Insulation Thicknesses. Insulation thicknesses in Table 25-G are based on insulation having thermal resistances in the range of 4.0 to 4.6 per inch of thickness on a flat surface at a mean temperature of 75°. Minimum insulation thickness shall be increased for materials having R values less than 4.0 or may be reduced for materials having R values greater than 4.6 per inch of thickness. 1. For materials with thermal resistance greater than R - 4.6, the minimum insulation thickness may be reduced as follows: 4.6 X Table 25-G Thickness = New Minimum Thickness Actual R 2. For materials with thermal resistance Iess than R = 4.0, the minimum insulation thickness shall be increased as follows: 4_ 0 X Table 25-G Thickness New Minimum Thickness Actual R (c) Vapor Barrier. Chilled water, refrigerant, and brine lines shall be insulated with a material which will have a continuous vapor barrier, to eliminate condensation in an ambient air temperature of 90°F, 80 percent relative humidity in zero air velocity. Barrier shall not be penetrated by pipe supports. 1. Except as otherwise noted, underground piping conveying a vapor or fluid which will be used to provide heating or cooling shall be insulated, vapor sealed and water-proofed. 2.

Apply with spray, glove or brush. After four hours, apply a second coat at the same rate --and embed a layer of glass fabric into the mastic. After 3-4 hours, a final coating of mastic shall be applied at the same rate to completely cover the glass fabric. (d) Condensate Drain Pipes. Condensate drain lines shall be insulated with a minimum of 3/8 inch thickness of foamed plastic, rubber based foam or other approved insulation which shall be installed on ~7iping material without longitudinal cuts. Circular joints shall be sealed with an approved adhesive. (e) Humidifier Water Lines.

DISCUSSION: Attached is the proposed ordinance adopting the 1991 Uniform Mechanical Code. This is in keeping with the policy of regularly updating the Mechanical Cade of the City of Fort Worth.. The Mechanical Board .has revised the ordinance to include changes primarily for the purpose of clarification and,to gain a closer uniformity with the Uniform Mechanical Code. All during their review of the UMC, the Board considered each item in the basic code to insure: a) that requirements are necessary to provide a minimal level of safety, and b) the most economical way to ach ieve the minimal level of safety was reached, and c) consideration was given to optimize the desires of Council to encourage development and construction. A Public Hearing was held by the Mechanical Board of Appeals on Tuesday, January 12, 1993. No one appeared in apposition to the proposed ordinance, therefore, the Mechanical Board recommends City Council adoption. MG:z QFFlCIAI RECORD C1~Y SF,CR~TARY ~'. WORTN, ~E~.
