(a) Thermal insulation shall be applied to piping where required to prevent freezing, to limit temperature losses in hot water piping, to prevent excessive condensation, and where surface condensation can result in damage to the building or contents, and where required to meet energy conservation requirements.
(b) Hot water storage tanks without heating capabilities shall be insulated to prevent excessive temperature loss and shall comply with all applicable energy conservation requirements.
(c) Insulation shall be applied to pipe and fittings in accordance with the manufacturer's instructions. All seams and joints shall be sealed. Insulation applied shall be for service intended.
(d) All insulation shall be jacketed to prevent damage and to restrict vapor or moisture migration. Jackets for the insulation of hot water tanks shall be corrosion-resistant metal.
(e) Where condensation may occur, hangers shall be placed outside of the insulation and shall include adequate shields or saddles to prevent damage.
(f) Insulation shall be of a thickness and have thermal "R" values appropriate for the application.
(g) Insulation shall have a flame spread of 25 or less and smoke developed of 50 or less, when tested in accordance with ASTM E84 (refer to Appendix A).
