Fire Rated Designs including Firestop 3M Intertek-Listed Components
Annular Spacing - Where annular spacing is specified in these listings for through-penetration type systems it refers to the clearance between the penetration and the opening. Where a specific distance is stated and not identified as "minimum", the penetration is centered in the opening; where a distance is specified as "minimum", the maximum spacing is governed by the maximum opening size; where a range is stated, the penetration may be offset in the opening within the clearance limitations of the spacing range given.
These systems are intended for use in the types of separations for which they are qualified in the listed design. The separations themselves should be rated for the period required per ASTM-E119, CAN/ULC-S101 or equivalent.
Systems are installed, unless otherwise noted, in accordance with the Manufacturer's Installation Instructions or Design Manual.
Penetrating items must be supported as required by applicable codes on both sides of the fire barrier. Listed Firestop systems that include support for the penetrating item indicate the supporting element in the listing. Such items are not evaluated for their load carrying capacity during the fire resistance test.
Certified Products can be identified by the Warnock Hersey (WH), or ETL Certification Mark
Manufacturers of listed components subscribe to an Intertek follow-up factory inspection and certification program.
