Materials Identification: <br /> [ ] Materials and equipment must be installed in accordance with the manufacturer's installation instructions. <br /> [ ] Materials and equipment must be identified so that compliance can be determined. <br /> [ ] Manufacturer manuals for all installed heating and cooling equipment and service water heating <br /> equipment must be provided. <br /> [ ] Insulation R-values, glazing U-factors, and heating and cooling equipment efficiency must be clearly <br /> marked on the building plans or specifications. <br /> Duct Insulation: <br /> [ ] Ducts in unconditioned spaces must be insulated to R-5. <br /> Ducts outside the building must be insulated to R-8.0. <br /> Duct Construction: <br /> [ ] All joints, seams, and connections must be securely fastened with welds, gaskets, mastics (adhesives), <br /> mastic-plus-embedded-fabric, or tapes. Tapes and mastics must be rated UL 181A or UL 181B. <br /> Exception: Continuously welded and locking-type longitudinal joints and seams on ducts <br /> operating at less than 2 in. w.g. (500 Pa). <br /> [ ] The HVAC system must provide a means for balancing air and water systems. <br /> Temperature Controls: <br /> [ ] Thermostats are required for each separate HVAC system. A manual or automatic means to <br /> partially restrict or shut off the heating and/or cooling input to each zone or floor shall be provided. <br /> Service Water Heating: <br /> [ ] Water heaters with vertical pipe risers must have a heat trap on both the inlet and outlet unless the <br /> water heater has an integral heat trap or is part of a circulating system. <br /> [ ] Insulate circulating hot water pipes to the levels in Table 1. <br /> Circulating Hot Water Systems: <br /> [ ] Insulate circulating hot water pipes to the levels in Table 1. <br /> Swimming Pools: <br /> [ ] All heated swimming pools must have an on/offheater switch and require a cover unless over 20% <br /> of the heating energy is from non-depletable sources. Pool pumps require a time clock. <br /> Heating and Cooling Piping Insulation: <br /> [ ] HVAC piping conveying fluids above 105 °F or chilled fluids below 55 °F must be insulated to the <br /> levels in Table 2. <br />
