Cast In Fire Collar / Cast In Device

Composition

QuelCast Fire Collars are constructed from a robust polypropylene material and contain a high performance intumescent material which reacts under the influence of heat. This will exert pressure on the pipe as it softens, to form a carbonaceous char which provides an effective insulation plug thus preventing smoke and fire passing through to the adjoining compartment.

• Fire resistance testing to BS EN 1366-3
• Up to EI240
• Classified to EN 13501-2

The standard QuelCast is 250mm high to suit a 250mm deep concrete slab but they can be reduced or extended to suit differing slab depths – this is a service that Quelfire offer in house so that the product is delivered to site ready to install, however it can be done on site too.

For instances where the slab depth is between 250 and 150mm, the process is: Remove the cap, Cut the top off with a saw, replace the cap and finally, we recommend sealing the cap with self-adhesive tape to ensure no concrete seepage.

For instances where the slab depth is greater than 250mm the QuelCast is fitted with an extension tube. To install these the process is: Remove the cap, insert the tube over the QuelCast body pushing down until fully seated, measure up from the base, cut the extension tube with a sharp saw or knife, replace the cap and finally, we recommend sealing the cap with self-adhesive tape to ensure no seepage.

Simple installations steps:

1. Mark the formwork with a cross where the pipe is to pass through the floor
2. Position the QuelCast Cast In Fire Collar as required (the centre line marks on the QuelCast Collars and Manifold help to position in the correct location)
3. Attach to the formwork using screws or nails through the holes in the 4 corners of the unit
4. Pour the concrete to the required depth
5. On completion of concrete curing, remove all formwork and shuttering
6. Remove the cap from the top of the QuelCast Collar
7. Place the pipe through the QuelCast Collar

Additional instructions for QuelCast50:

No extra work, backfill or sealant is required where the correct diameter pipe is used in the correct QuelCast. For QuelCast50, cable bunches and where smaller diameter pipes are used inside larger collars a mineral wool smoke seal backfill is required in the top of the QuelCast.

For 110mm diameter pipes inside a QuelCast110 and 160mm in a QuelCast160, no backfill is required.

For more in depth installation information refer to the QuelCast Installation Guide.

QuelCast Manifold Recess Former

The QuelCast Manifold has been designed and developed to create a 70 mm recess in the floor slab either on the top or on the bottom of the floor slab to allow for applications where there is limited ceiling space and so the plastic pipe can be installed closer to the ceiling with the pipe connection recessed in the slab.

For example:

• Soil pipe manifolds
• Pipe connections
• Limited ceiling space

When installing a QuelCast Manifold Recess Former to the underside of the slab the process is: cut the spigot off the manifold, position the QuelCast on the manifold within the indentations, secure together using self tapping screws through each corner of the QuelCast body and then install as a whole unit using the centre line indicators on the Manifold Recess Former as a guide instead of the QuelCast.

When installing a QuelCast Manifold Recess Former on the top of the slab, the process is: remove the cap, cut/extend the QuelCast body to suit the slab depth taking into consideration the depth of the Manifold Recess Former, push the Manifold onto the QuelCast until fully seated, ensure the temporary shuttering infill is in place and sealed with tape and then install the whole unit as normal.
