4 of 35 12/3/2015 7:13 AM Public Input No. 31-NFPA 90A-2015 [ Section No. 4.3.2.1 ] 4.3.2.1 Air connectors are limited-use, flexible air ducts that shall not be required to conform to the provisions for air ducts where they meet the requirements of 4.3.2.1.1 through 4.3.2.1.5 6. 4.3.2.1.1 Air connectors shall conform to the requirements for Class 0 or Class 1 connectors when tested in accordance with ANSI/UL 181, Standard for Safety Factory-Made Air Ducts and Air Connectors. 4.3.2.1.2 Class 0 or Class 1 air connectors shall not be used for ducts containing air at temperatures in excess of 121 C (250 F). 4.3.2.1.3 Air connector runs shall not exceed 4.27 m (14 ft) in length. 4.3.2.1.4 Air connectors shall not pass through any wall, partition, or enclosure of a vertical shaft that is required to have a fire resistance rating of 1 hour or more. 4.3.2.1.5 Air connectors shall not pass through floors. 4.3.2.1.6 An air connector shall not be interrupted by a short collar or any other fitting on one side and then connected to another air connector on the other side when penetrating (a) a floor or (b) a wall, partition or enclosure of a vertical shaft that is required to have a fire resistance rating of 1 hour. The requirement that Air Connectors shall not pass through any wall, partition, or enclosure of a vertical shaft that is required to have a fire resistance rating of 1 hour or more and Air Connectors shall not pass through floors is not sufficiently clear. The confusion comes in understanding exactly what is considered passing through? ASHRAE s TC 5.2 s Codes & Standards Interaction Sub-Committee extensively discussed this in meetings recently and they plan to request an interpretation from NFPA 90A & 90B about this. It is known that Air Connectors are being used to transport air up to the plane of a floor or wall, then interrupted by a short collar or other metal fitting, and then continued on the opposite side. Many inspectors consider this as not passing through and thus are allowing it to be done. This should not be acceptable to NFPA 90A or 90B. It is also known that Air Connectors are being used in basement applications where the ceiling is then finished out in gypsum board. Is this considered acceptable? In what plane is the passing through limitation considered? Can an Air Connector pass through floors in the horizontal plane? It is important that the correct information is provided to users of NFPA 90A & 90B. It seems that some clarification is needed for this important aspect of Air Connector use limitation to be properly understood and conveyed.

Exception: Plastic water distribution piping and tubing listed as having a maximum peak optical density of 0.5 or less, an average optical density of 0.15 or less, and a maximum flame spread distance of 1.5 m (5 ft) or less when tested in accordance with ANSI/UL 2846, Fire Test of Plastic Water Distribution Plumbing Pipe for Visible Flame and Smoke Characteristics, and installed in accordance with its listing, shall be permitted to be used within a raised floor plenum.

(2) Flame does not spread to the outer extremities of the sample. (3) Flashover, based on the criteria from NFPA 286, does not occur. (4) The peak heat release rate does not exceed 800 kw.

Some interpret the section to require dynamic fire dampers when an air handling system is designed to shut down during a fire event. This change will help clarify that, where a system is designed to shut down during a fire event (duct detector in discharge), no dynamic fire dampers are required. Another option would be to add an annex note if this verbiage is not acceptable. Submitter Full Name: PETER LARRIMER Organization: US DEPARTMENT OF VETERANS AFFA Submittal Date: Thu Jun 25 14:26:14 EDT 2015 Resolution: The committee finds that there is insufficient justification for this change.

7 of 35 12/3/2015 7:13 AM Public Input No. 32-NFPA 90A-2015 [ Section No. 6.4.3.1 ] 6.4.3.1 Smoke detectors provided as required by 6.4.2 shall automatically stop and instantaneously stop their respective fan(s) on detecting the presence of smoke. With the introduction of automated energy management systems it is possible to have extensive time delays inherent to shutting down air handlers. Currently there is no maximum time specified to which fans must stop upon detection of smoke. Time durations in excess of 60-90 seconds have been observed in order to have a sequential and orderly shut down for the protection of the equipment. In a fire/smoke condition the air handler is the threat and should NOT be protected at the risk of the building occupants, first responders, or the protected property itself. Perhaps the Technical Committee would be more familiar with using the term shunt rather than stop which implies instantaneous shut down. The TC may also be more comfortable adding a time limit for the shut off.

A.4.3.3.2 Aerosol duct sealants for use with sheet metal ducts are not addressed within the scope of ANSI/UL181A or ANSI/UL181B, Aerosol duct sealants intended for use with sheet metal ducts are addressed by UL1381, Outline of Investigation for Aerosol Duct Sealant. Aerosol duct sealants are intended to seal minor holes and gaps within sheet-metal air ducts fabricated and installed in accordance with ANSI/SMACNA "HVAC Duct Construction Standards - Metal and Flexible.". UL 1381, Outline of Investigation for Aerosol Duct Sealant, provides requirements to evaluate these sealants for this application, including surface burning characteristics, mold growth and humidity, erosion, interior duct burning, leakage reduction, and durability. These tests are based on requirements in ANSI/UL 181, ANSI/UL 181A, ANSI/UL 181B and ASTM E2342. UL 1381 requirements are limited to application in ducts with individual openings no greater than 5/8 in. diameter, and seam/joint openings no greater than 5/8 in. across. These sealants are not intended for use as a substitute or to supplement mechanical attachment in the sheet-metal duct systems. These sealants are not intended for use with rigid fiberglass ducts, flexible-wire helix ducts, or spirally wound metal ducts not complying with SMACNA Standards. Aerosol duct sealants are intended to be applied by trained professionals and specifically in accordance with accompanying installation instructions.
