How To Install Your Intumescent Fire Grilles

- Suitable for fitting up to 1,000mm (1m) from floor level. The top of the grille should not be higher than 1000mm from the floor.
- For block work installation, block work should be a minimum of 75mm thick and with a suitable lintel above the grille so that the grille is non-load bearing.
