INSTALLATION

asrto_strip_06If the fire doors or door frames have not been previously rebated, check the manufacturer’s specifications in order to match the size and quantity of required intumescent sealing product.

The width of the rebate must take account of the margin due to the shrinkage of wood or paint layer, and therefore it is recommended to use a cutter about 3% wider than the size of the seal. It is recommended that the gap between the door and door frame is not be greater than 4 mm.

In order to fit the seal, remove the protective paper from the adhesive tape and press the seal carefully into a rebate over the entire length. For alternative methods of installation, use firestop acrylic mastic Astro Intumescent Mastic or steel pins.

Carefully move the door to the installation site and remove the redundant edges using a suitable saw or a plane. Cut the profile and the seal to the size matching the door edges. Remove sharp edges with a file or sandpaper, remove the old seal.

Fix the profile using 12 1-inch screws included in the kit.

Tear off the self-adhesive backing tape and attach the seal to the edge of the door by pressing it firmly. Make sure the seal adheres properly.

Hang the door on its hinges.
