Application Instructions

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 & 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
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.
