Fitting Instructions
These seals are rebated into the edges of double-acting, double leaf pivot or hinge fire doors. It is essential that the correct width of rebate is cut as remrdial work can cost time and money. Norseal recommend that the groove be routed to give a ‘light press fit’ for the extrusion. The seal should finish flush with the timber.
Seal | Extrusion Width | Extrusion Depth |
---|---|---|
IMN | 20.5 mm | 6.0 mm |
IMP | 20.5 mm | 6.0 mm |
The recommended door-to-door gap and door-to-frame gap is 3 mm.
Fitting IMN/IMP
- On double leaf swing doors IMN is fitted into the edge of one meeting stile
- It is also fitted into the head rails and hanging stiles of both doors
- Alternatively, IMN may be fitted into the head and jambs of the door frame
- IMP is fitted into the opposing meeting stiles of the second door
- NOTE: At the meeting stiles the IMN blade insert must only make contact with the curved face of IMP and not with the door edge
