Installation instructions

Collar installation using dowels / screws:

Pursuant to Section 4 of the Technical Approval document, use of steel expansion anchors and M6 screws, FLAMRO Art No. 17305, is required. For penetrations through lightweight partitions, continuous threaded rods M6 must be used, FLAMRO Art. No. 17300 (if desired, they can also be used for solid building components).

Installation procedure:

Bend the metal straps outside, fasten the collar slipped onto the pipe with the clamp, move the assembly to the building component, mark the position of the boreholes, then drill the required holes for the dowels. After inserting the drop-in anchor, screw on the collar with the metal straps using washers and nuts. In case of continuous threaded rods being used, two opposite straps must be screwed with each other.

Collar installation using mortar:

If firestop collar Variant “PLUS” is used, first surround the pipe with the sound insulation strip and secure the strip with adhesive tape (leave out this step if you use the collar without sound insulation properties). Then insert the collar into the through-penetration opening to the level of the label’s edge, and seal with cement mortar or a mineral building material falling into building materials class DIN 4102-A (the label must remain fully visible after collar insertion and application of mortar). For installation of pipe bends, please see the additional information provided in Sections 3.3 and 4.2.6 of the Technical Approval document (perhaps use of the FLAMRO Variant special collar). A maximum of 3 pipes with an outside diameter of up to 50 mm each may be routed through the installed collars, or 2 pipes with an outside diameter of up to 63 mm each. The pipe penetration seal must be permanently labelled by the installation company. The label has to be affixed to the building component next to the pipe penetration seal. (Information on approved pipe materials, pipe diameters and pipe wall thicknesses is provided in Section 3.2 of Technical Approval document Z 19.17-1269.)
