QWR CE Marked Fire Collars should be used where a plastic pipe penetrates a fire rated wall or floor. For vertical pipework, one unit should be installed to the underside of the floor. For horizontal pipework one unit should be fitted to each side of the wall.
The soffit of the floor or the face of the wall must be smooth and where there are irregularities in the surface, the space between the flange of the unit and floor or the wall should be made good using QSS QuelStop CE Marked Intumescent Acoustic Acrylic Sealant.
The QWR CE Marked Fire Collar should be fed around the plastic pipe, securing the ends together by passing the tongues on one end through the slots on the other end. The tongues should then be bent back and the unit secured to the structure using the integral fixing lugs.
The QWR CE Marked Fire Collar must be secured to concrete and masonry construction using steel sleeve anchors. Where fitting to a plasterboard partition wall one QWR CE Marked Fire Collar should be installed on either side of the partition and fixed using through-bolts or steel hollow wall sleeve anchors.
QWR CE Marked Fire Collars can also be installed in conjunction with the QB50 QuelStop Ablative Coated Mineral Wool Fire Batt. Please refer to Quelfire Technical department for details.
Quelfire QWR Fire Collars have also been tested generally in accordance with the BS EN 1366-3: 2009 fitted to plasterboard ceilings, please contact Quelfire technical department to discuss your application.
