4.3.2.1

Air connectors are limited-use, flexible air ducts that shall not be required to conform to the provisions forair 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 inaccordance 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 of121°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 tohave 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 thenconnected to another air connector on the other side when penetrating (a) a floor or (b) a wall, partition orenclosure 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.

UL 2846 is an ANSI standard that includes a test method for determining valuesof flame propagation distance and optical smoke density for individual pairs of plastic plumbing pipesfor distribution of potable water that can be installed in ducts, plenums, and other spaces used forenvironmental air. The scope of this standard can be viewed at http://ulstandards.ul.com/standard/?id=2846. The acceptance criteria specified (peak optical density not greater than 0.50, an averageoptical density not greater than 0.15, and a flame spread distance not greater than 5 feet) isconsistent with values in Sections 4.3.11.5.5.1 through 4.3.11.5.5.4.

4.3.11.6.2

Foam plastic insulation shall not be used as wall or ceiling finish in plenums unless the insulation meetsany one of the criteria shown in 4.3.11.6.2.1,through 4.3.11.6.2.2 , or 4. 3.11.6.2.3.

4.3.11.6.2.1

The foam plastic insulation material shall exhibit a flame spread index of 25 or less and a smoke developedindex of 50 or less when tested in accordance with ASTM E 84 E84 , Standard Test Method for SurfaceBurning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test for Surface BurningCharacteristics of Building Materials, at the maximum thickness intended for use, and shall also complywith the following criteria, when tested in accordance with NFPA 286, Standard Methods of Fire Tests forEvaluating Contribution of Wall and Ceiling Interior Finish to Room Fire Growth ( where the testng shall beperformed on the finished foam plastic assembly related to the actual end-use configuration and on themaximum thickness intended for use) :

(1) Flame does not spread to the ceiling during the 40 kW exposure.

(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.

(5) The total smoke release does not exceed 1000 m2 (1196 yd2) when tested in accordance with NFPA286, Standard Methods of Fire Tests for Evaluating Contribution of Wall and Ceiling Interior Finish toRoom Fire Growth (where the testing shall be performed on the finished foam plastic assemblyrelated to the actual end-use configuration and on the maximum thickness intended for use) .

4.3.11.6.2.2

The foam plastic insulation material shall be covered by corrosion-resistant steel having a base metalthickness of not less than 0.4 mm (0.0160 in.) and shall exhibit a flame spread index of 75 or less and asmoke developed index of 450 or less when tested in accordance with ASTM E 84 E84 , Standard TestMethod for Surface Burning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test forSurface Burning Characteristics of Building Materials, at the maximum thickness intended for use.

4.3.11.6.2.3

The foam plastic insulation material shall be separated from the plenum by an approved thermal barrierconsisting of 12.7 mm (0.5 in.) gypsum wallboard or a material that is tested in accordance with and meetsthe acceptance criteria of both the temperature transmission fire test and the integrity fire test of NFPA 275,Standard Method of Fire Tests for the Evaluation of Thermal Barriers Used Over Foam Plastic Insulation,and shall exhibit a flame spread index of 75 or less and a smoke developed index of 450 or less whentested in accordance with ASTM E 84 E84 , Standard Test Method for Surface Burning Characteristics ofBuilding Materials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of BuildingMaterials, at the maximum thickness intended for use.

4.3.11.6.2.4

The foam plastic insulation material shall be separated from the plenum by not less than 25.4 mm (1.0 in.)of masonry or concrete and shall exhibit a flame spread index of 75 or less and a smoke developed indexof 450 or less when tested in accordance with ASTM E84, Standard Test Method for Surface BurningCharacteristics of Building Materials , or ANSI/UL 723, Standard for Test for Surface BurningCharacteristics of Building Materials , at the maximum thickness intended for use.


This public input does three things.

1. It clarifies that it is unnecessary to test a barrier that is masonry or concrete at 1 inch or more in thickness to

assess whether it complies with NFPA 275. Clearly such a thickness of concrete will be at least as good a thermal barrier as 1/2 inch gypsum board. Some users were demanding NFPA 275 testing.

2. The reference to NFPA 286 is being moved to where it belongs, in the charging paragraph, because items 1 through 5 are based on testing to NFPA 286 and not testing to ASTM E84.

3. The criteria for flashover need to be those from NFPA 286.

Public Input No. 28-NFPA 90A-2015 [ Section No. 5.4.5.4 [Excluding any Sub-Sections] ]

Dampers Where an air handling system is designed to operate during a fire event, dampers shall closeagainst the maximum calculated airflow of that portion of the air duct system in which they are installed.


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.

6.4.3.1

Smoke detectors provided as required by 6.4.2 shall automatically stop and instantaneously stop theirrespective 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.

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.

A.7.2

See NFPA 105, Standard for Smoke Door Assemblies and Other Opening Protectives, for testingrequirements for smoke dampers and combination fire and smoke dampers. See NFPA 80, Standard forFire Doors and Other Opening Protectives, for testing requirements for fire dampers. AMCA International’sGuide for Commissioning and Periodic Performance Testing of Fire, Smoke and Other Life Safety RelatedDampers provides guidelines from damper manufacturers on how to test dampers for acceptance testingand for follow-up periodic testing. The testing should be performed under normal conditions therefore therequirement has been added to test them via any access doors to ensure that they are truly accessible forservice.
