- Intumescent paper cools the lock, hinges, and screws and protects them from overheating in the event of a fire
- Self-closing hinges can be individually adjusted, for example to have more tension, or to allow for buckled door tops

HINGE, LOCK AND DOOR CLOSER PROTECTION:
HINGES: Remove hinges from both door and frame, cut the cut the Envirograf® intumescent paper to size to size, sandwich it between hinge and rebate on both door and frame then screw the hinges back.
LOCK AND KEEP: Remove lock, cut the Envirograf® intumescent paper to size, wrap it around the lock and sandwich it
between the lock and door as you replace the lock. Place paper under the keep plate as well.
DOOR CLOSER: Before fitting a door closer sandwich pre-cut cut the Envirograf® intumescent paper between the closer
and the door face then fasten the closer to the door. When ordering state the size of intumescent paper required for your door closer.
SELF CLOSING HINGES: DO NOT peel off the grey intumescent paper on the back of the hinges: it is an essential part
of the fire protection product! Ensure there is a gap of 3½ – 4mm at the head and closing side and a 1mm gap on the hinge
side. Fit the hinges to the door and frame and see whether the door closes without adjustment If adjustment is required, then adjust the top and bottom hinges with the larger Allen key to close the door fully onto the seals without slamming. Then insert the grub screw into the threaded hole and tighten fully with the smaller Allen key. Adjust the centre hinge slightly tighter than the other two hinges to latch.
Allen keys and screws are supplied with the set of three hinges.
