714.1 Scope.
The provisions of this section shall govern the materials and methods of construction used to protect through-penetrations and membrane-penetrations of horizontal assemblies and fire-resistance-rated wall assemblies.
714.1.1 Ducts and air transfer openings.
Penetrations of fire-resistance-rated walls by ducts that are not protected with dampers shall comply with Sections 714.2 through 714.3.3. Penetrations of horizontal assemblies not protected with a shaft as permitted by Section 717.6, and not required to be protected with fire dampers by other sections of this code, shall comply with Sections 714.4 through 714.5.2. Ducts and air transfer openings that are protected with dampers shall comply with Section 717.
714.1.2 Special inspection.
All through-penetration and membrane-penetration firestop systems shall comply with the special inspection requirements of Chapter 17.
714.2 Installation details.
Where sleeves are used, they shall be securely fastened to the assembly penetrated. The space between the item contained in the sleeve and the sleeve itself and any space between the sleeve and the assembly penetrated shall be protected in accordance with this section. Insulation and coverings on or in the penetrating item shall not penetrate the assembly unless the specific material used has been tested as part of the assembly in accordance with this section.
714.3 Fire-resistance-rated walls.
Penetrations into or through fire walls, fire barriers, smoke barrier walls and fire partitions shall comply with Sections 714.3.1 through 714.3.3. Penetrations in smoke barrier walls shall also comply with Section 714.4.3.
714.3.1 Through-penetrations.
Through-penetrations of fire-resistance-rated walls shall comply with Section 714.3.1.1 or 714.3.1.2.
Exception: Where the penetrating items are steel, ferrous or copper pipes, tubes or conduits, the annular space between the penetrating item and the fire-resistance-rated wall is permitted to be protected by either of the following measures:
1. In concrete or masonry walls where the penetrating item is a maximum 6-inch (152.4 mm) nominal diameter and the area of the opening through the wall does not exceed 144 square inches (92 903 mm
2
), concrete, grout or mortar is permitted where installed the full thickness of the wall or the thickness required to maintain the fire-resistance rating.
2. The material used to fill the annular space shall prevent the passage of flame and hot gases sufficient to ignite cotton waste where subjected to ASTM E 119 or UL 263 time-temperature fire conditions under a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water at the location of the penetration for the time period equivalent to the fire-resistance rating of the construction penetrated.
714.3.1.1 Fire-resistance-rated assemblies.
Penetrations shall be installed as tested in an approved fire-resistance-rated assembly.
714.3.1.2. Through-penetration firestop system.
Through-penetrations shall be protected by an approved penetration firestop system installed as tested in accordance with ASTM E 814 or UL 1479, with a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water and shall have an F rating of not less than the required fire-resistance rating of the wall penetrated.
