Installation Techniques 1. Install 3M Fire Barrier Pillows so the 9 in. (22,8 cm) dimension travels through the wall, or floor. 2. One of the large faces of the 3M Fire Barrier Pillow shall face the framing of the penetration. 3. A mixture of following pillows may be necessary to obtain the correct compression (20% - 25% compression). FB 249: 2 in. x 4 in. x 9 in. (50,8 mm x 101,6 mm x 228,6 mm) FB 269: 2 in. x 6 in. x 9 in. (50,8 mm x 152,4 mm x 228,6 mm) FB 369: 3 in. x 6 in. x 9 in. (76,2 mm x 152,4 mm x 228,6 mm) 4. Begin by installing as many FB 369 pillows, as possible. Then install additional FB 269 and FB 249, as needed, to complete the installation. Storage The 3M Fire Barrier Pillows must be stored in a dry warehouse environment. Pallets should not be stacked. Methods: 1. Choose the appropriate firestop system in the 3M Fire Protection Products Applications and Specifiers Guide, or the UL Fire Resistance Directory. 2. Starting in the bottom corners of the penetration, install 3M Fire Barrier Pillows vertically so that the large faces of the pillows are facing the framing. See picture. 3. Fill in the space between vertical pillows with pillows installed horizontally in rows. 4. Repeat steps 2 and 3 until the penetration is completely full. See Figure 2. 5. If required, apply a minimum 1 in. (25,4 mm) depth of 3M Moldable Putty+ in all four corners between the vertical pillow and framing. 6. Check for any openings between pillows (and penetrating items) greater than 1/16 in. (1,5 mm) Fill any openings between 1/16 in. (1,5 mm) and 1-1/2 in. (38 mm) with a minimum 1 in. ( 25,4 mm) depth of 3M Moldable Putty+. L Rating: See UL Listing. Calculating Pillow Requirement: Measure the opening, in inches, and multiply the length by the width to get the total area. Estimate the area occupied by the penetrating items and subtract it from the area of the opening. This is the amount of area to be firestopped. Installation shall be in strict accordance with manufacturer's written instructions. The product shall be classified by Underwriter's Laboratory, Inc. as a Fill, Void and Cavity Material. When installed in accordance with systems outlined in the current UL Fire Resistance Directory and tested in accordance with ASTM E 814 and (UL 1479), up to a 3 hour rating is achieved. For example, an opening through a gypsum wall measures 30 in. x 18 in. (76 cm x 45 cm). The openings area 30 in. x 18 in. (76 cm x 45 cm) is 540 sq. in. (3483 sq. cm). A 24 in. x 4 in. (60,9 cm x 10 cm) cable tray which is 40% full of cables is running through the opening. The tray occupies an area 0.4 in. x 24 in. x 4 in. (10,1 mm x 60,9 cm x 10 cm) of 38.4 sq. in. (247,7 sq, cm). The amount of area to be firestopped 540 sq. in. - 38.4 sq. in. (3483 sq. cm - 247 sq. cm) is 501.6 sq. in. and three FB 249 pillows to properly firestop this penetration. After calculating the amount of area to be firestopped determine the number of each size pillow needed to firestop the penetration. In most penetrations you will need to use some of each of three sizes of pillows. Determine the number of each pillow by dividing the total area by the pillows Estimating Number and round up the nearest whole pillow. See Table1. In this example it should take approximately twenty-five FB 369 pillows, eleven FB 269 pillows, 7. Maintenance Inspection: Installations should be inspected periodically for subsequent damage. Damaged pillows shall be replaced. Pillow Size Estimating Number Example (501.6 sq. in.) (3232 sq. cm) FB 369 3 in. x 6 in. x 9 in. 20.3 501.6/20.3 = (25) pillows 49.4 501.6/49.4 = (11) pillows 172.0 501.6/172.0 = (3) pillows (76,2mm x 152,4mm x 228,6mm) FB 269 (2 in. x 6 in. x 9 in.) (50,8mm x 152,4mm x 228,6mm) FB 249 (2 in x 4 in. x 9 in.) Retrofit: Cables may be added or replaced by simply removing and replacing pillows and putty as required. 8.
