Whnre zone healing and cooling are conWlled by separete zone thertnostals,means(such as limit switches,mechanical stops,or,for DDC systems,software piogramming)must be provided to prevent simultaneous heating and cooling lo tho zone. 9. Stair and eleva�or shaft venls niust be equipped vrith molonzed dampers capable of being automalically closed dunng rwrmal bwlding operation and intertocked to open as required by fire and smoke detection systems. All gravity outdoor air supply and exhaust hoods, venis,and ventilators musl be equipped with motoriznd dampers that will automatically shul when the spaces served are nol in use. Exception(s): - Ventilation systoms serving unconditioned spaces. - Graviry(non-motorized)dampers are accepta6le in buildings less than three slories in height above grade. 10. Whore a zone is served 6y a system(s)with bolh humidification and dehumidifiption capability,means(such as limit switches, mechanical stops,or softwere programming)must be provided to prevent simultaneous operation of humidification and dehumidification equipment. Exceplion(s): - Zones served by desiccant systems,used with direct evaporative cooling in series;Syslems serving zones where specific humidiry levels are roquired. 11. All freeze proteciion systems,including sell-regulating I�eat tracing,mus�inGude automatic contmis capable o(shutting oM lhe systems whun outsido air temperatures are above 40"F or when the wiWitions oF tha pfotected tluid vrill prevent froezing. Snow-and ice-mellirg syslems must indude automatic conlrols capable of shutling otf the systems when the pavement�emperalure is above 50°F and no precipitation is falling,and an automatic or manual wniml that�rill allow shutoff when the outdoor tem{w2ture is abovc 40°F. 12. Duct and pipe insulation exposed to weather must be suitabla for outdoor service:e.g..Dro�eded by aluminum,sheel metal,painled canvas,or plaslic cover. Ceilular foam insula6on must be protoded as above or painted with a coating Uiat is wa�er retardant anZ provides shieWing from solar radiation Ihat can causo degrada6on ol ihe malerial.Insulation covering chilled water piping,refrigerant suclion piping,or cooling ducls located outside the conditioned space must include a vapor retardant located outside the insulation (unless the insulalion is inherently vapor retardant),all penetrations and joints of which must be sealed. 13. Duct Soaling Requiroments: a)Pressure sensitive tape used as the primary sealanl is certifed to comply with UL-181A or UL-181B, 6)Longitudinal and transverse seamc for ducts in unconditioned spaces, c)Longitudinal and transverso seams and dud wall peneVations fc+r duds outside the building. i d)T2nsverse seams on buried ducis 74. Gutdoor air supply�nd exhaust systems must have motorized dampers that automalically shW when the systems or spaces served are not in use. Dampers must be capable of automatically shutting off durirg preocwFancy building wamrup,cool[fown,and selback, excepl when venlilaUon reduces energy cosls(e.g.,night purge)or when ventilation must be supplied to meel code requiremenis.Both outdoor air supply and exhaust air dampers must have a maximum leakage rate of 3 cfml(t2 at 7.0 In w.g.when tested in accordance with AM�A Standard.ri00.
