Composition:

The CFC Ceiling Fan Cuffs consist of a continuous pressed stainless steel flexible shell containing a high performance graphite based intumescent material which reacts under the influence of heat to exert pressure on the duct as it softens to form a carbonaceous char which provides an effective insulation plug thus preventing fire passing through to the adjoining compartment. The CFC has built in spring clips which hold it to the plasterboard ceiling.

The CFC has been tested in the scenario shown on the specific manufacturers’ fan units. The customer/installer should satisfy themselves, or consult a fire engineer that the product, test data available, standards to which the product is tested, fan units and ducting, floor/ceiling construction is applicable and satisfactory for their specific scenario as Quelfire are not able to comment on each and every scenario.

The CFC Ceiling Fan Cuff has been tested generally in accordance with BS EN 1364-2 Fire Resistance Tests for non-loadbearing elements – Part 2: Ceilings and additional guidance from BS EN 1366-3. (Test Report WF424611 and WF510322)

1. Cut the plasterboard aperture to Ø135mm around the Ø100mm PVC duct spigot.
2. Centralise the PVC duct spigot within the hole.
3. From the underside push the Quelfire CFC up into the aperture around the PVC duct ensuring the spring clip clamps fully back onto the plasterboard and that the Quelfire CFC is clamped tight in position.
4. Make sure the gap between the CFC and the plasterboard is clean of any debris and remove dust from all edges.
5. Seal the small gap between the CFC and the plasterboard and around the power cable with QuelStop Intumescent Acrylic Sealant.
6. Install the ceiling fan to the plasterboard with correct screw fixings in accordance with the ceiling fan manufacturers requirements.
