Instruction Manual
INSTALLATION INSTRUCTIONS
This installation guide is intended for general information only and all details should be checked against relevant supporting test evidence and certification.
Quelfire QRS Fire Sleeves are lifesaving products designed to prevent the
spread of fire where plastic vent ducts penetrate fire compartment walls. It
is therefore essential that they are fitted in a responsible and workmanlike
manner.
QRS Fire Sleeves are suitable for use in various wall constructions including
solid concrete masonry/block walls and flexible fire rated plasterboard
partitions with and without the QuelStop Fire Batt system. Fire ratings vary
depending on the substrate and services so refer to the technical data and
installation details for full details.
Apertures for the QRS should be cut or drilled as tight as practically
possible to suit the external dimensions of the QRS Fire Sleeve. Suggested
aperture sizes are provided in the table below and we would always recommend
carrying out a trial on site:
Product Code| Duct Size (mm)| Approx. space needed around ductto
fit QRS Fire Sleeve (mm)| Recommended approx. aperture (mm)
---|---|---|---
QRS110/54| 110 x 54| 13| 135 x 78
QRS205/60| 205 x 60| 13| 230 x 85
QRS220/90| 220 x 90| 22| 262 x 132
QRS75| 75 Ø semi-rigid| 8| 90 Ø
QRS90| 90 Ø semi-rigid| 13| 116 Ø
QRS110| 100 Ø| 18| 135 Ø
QRS130*| 125 Ø| 23| 170 Ø
QRS110/54SS| 110 x 54| 8| 126 x 70
QRS204/60SS| 204 x 60| 8| 219 x 75
QRS220/90SS| 220 x 90| 12| 244 x 114
*QRS90, QRS130 and QRS110 are not currently CE Marked
Gaps around the installed QRS Fire Sleeve should not exceed 5mm and can
therefore be sealed with QuelStop Intumescent Acrylic Sealant.
The QRS can be retrofitted but is dependent on being able to cut the right
size aperture within the wall substrate which may be easier to achieve without
the duct in position.
The normal and easier installation is to build the wall around the QRS Fire
Sleeve and duct.
Installation principles of the Quelfire QRS Fire Sleeve
- Once the correct diameter hole or aperture has been achieved within the wall and the correct QRS Fire Sleeve has been identified, check the duct and penetration are clean of debris and there are no obstructions that would prevent the QRS being slid into position.
- Hinge open the QRS Fire Sleeve and wrap tight around the plastic vent duct.
- Secure the lid of the QRS shut with the self-adhesive tape fitted to the rectangular versions (or the self tapping screw supplied with circular versions).
- The QRS Fire Sleeve can then be slid along the duct into the substrate.
- Ensure that the QRS Fire Sleeve is centrally positioned within the wall and that the face of the QRS is either flush or
- protruding from the substrate in accordance with the specific installation detail – check both sides. Seal around the perimeter of the QRS where it meets the substrate with QuelStop Intumescent Acrylic Sealant.
- Where the duct is required to be insulated, this can now be butted up to the QRS Fire Sleeve and sealed in accordance with
manufacturer’s recommendations.
Example Installation 1 – Direct to flexible or rigid walls
Drill or cut the hole in accordance with the details provided in the table
above then install as described above ensuring the minimum required protrusion
is achieved on both sides of the wall and finally seal both sides of the wall
with QuelStop Intumescent Acrylic Sealant.
Example Installation 2 – Multiple (stacked/side-by-side/cluster) ducts
Multiple ducts/QRS can be installed as a cluster and the QRS should be
installed in accordance with the details given above.
Once finally positioned, the QRS should be touching, 0mm between each, and
sealed around the perimeter. If the QRS are not touching then they need to be
far enough apart so as to be able to practically and robustly install and seal
the sleeve in the original wall construction or QuelStop Fire Batt. 50mm is
usually regarded as an absolute minimum space, but 100mm is much more
practical.
Example Installation 3 – In conjunction with QuelStop Fire Batt
In the case of oversized holes or formed letterboxes, depending on the
services, it may be possible to use the QRS Fire Sleeve in conjunction with a
single or double layer of QuelStop Fire Batt.
In these cases, the QRS should be installed first as described above and then
during final positioning and before sealing in place, the QuelStop Fire Batt
should be installed in accordance with separate supporting documentation.
Packaging & Storage:
Quelfire QRS Fire Sleeves are supplied individually to suit specific vent duct
sizes and may be packaged in cardboard boxes for shipping purposes and should
be stored in a cool, dry location.
Health & Safety:
QRS CE Marked Fire Sleeves consist of a pressed stainless steel shell
containing graphite in a synthetic compound with the addition of filters and
process oils.
The steel shells can have sharp edges, always wear gloves when handling.
