™ For uPVC pipe over 160mm: Use Fire Collar

- Make measuring points according to pipe size

- Cut fire collar at marked measuring points according to pipe size

- Ben the intumescent side of the collar until it snap

- Shape the collar to fit the pipe and bevel intumescent edge for close fit

- Wrap the collar around the pipe and clip the first bracket into slots on both ends

- Complete other brackets and fit the collar onto wall/slab
