door heights less than 1200mm the quantity of hinges may be reduced to 2No. For door heights over 2300mm an
additional hinge is required.
It is recommended that the door leaf (leaves) are used as the template for the installation of the frame. The operating
gaps between the door and the frame should comply with BS4787. Under door gaps for installed doorsets should
comply with BS4787 OR, if smoke sealed, by reference to the appropriate sections of BS5588. Notwithstanding this,
the maximum approved operating gaps for these doorset designs for fire door applications are:
Stiles, (including meeting stiles) and Head = 4mm.
Threshold up to 10mm to allow for floor coverings.
Door leaves may be reduced in height and width by up to 5mm at the time of installation. However, door leaf stile and
head dimensions should not be reduced below the minimum recommended by reference to the minimum
dimensions described for each design in this manual.
Doorsets should be installed into a suitable structure in accordance with guidance to be found by reference to
BS8214 : 1990 'Code of Practice for Fire Door Assemblies with non-metallic leaves'. The supporting construction
must be capable of staying in place and intact for the full period of fire resistance required for the doorset. The frame
jambs are to be fixed to the supporting structure using steel fixings at max. 600mm centres. The fixings must be of an
appropriate type for use with the supporting construction and must penetrate to a minimum depth of 40mm. The use
of an addition fixing through the frame head is recommended where the doorset width exceeds 1000mm.
Care should be taken to ensure that frame fixing positions do not conflict with ironmongery positions

advantages are:
� Operating gaps (which may contain edge seals) can
be maintained.
� Doors are delivered when site conditions are suitable.
Using the ‘first-fix’ method, doorframes are built in

Architectural & Specialist Door Manufacturers Association
6.1.2 Hinges
Hinges must be able to support loads imposed by
the door leaf and hardware functions such as selfclosing
and back check.
Consult the hardware supplier if necessary.
� Use 3 hinges per door leaf for all fire doors above
1200mm in height unless otherwise specified.
� When door leaves exceed 2250mm in height or
160kgs (weight), consult the hardware supplier. One
or more additional hinges may be required.
Note: Hinges should be located to conform to the hinge
manufacturers recommended position. In the absence of
such guidance it is recommended that the top hinge
should be located to centre not more than 200mm from the
top of the door. The bottom hinge should be centred not
more than 250mm from the bottom of the frame jamb (this
will clear most kick plate requirements). The third hinge
may be centred between the top and bottom hinge (if
required by reference to fire test / assessment data) OR
approx. 200mm below the top hinge.
6.2 Installation second fix
6.2.1 Packing
� Pack between the doorframe and the prepared
opening immediately above each fixing position.
Ensure that the door assembly, when in position is
perfectly plumb and square. The best practice is to use
the hung door leaf as the fixing template. Avoid later
shrinkage by using packing that is durable, hard and
stable. The use of proprietary ‘trouser leg’ packers is
recommended. Alternatives are offcuts of laminate, or
plywood.
� Ensure that jambs are straight, operating gaps are
even and within tolerance and that fixing screws
cannot distort the frame when tightened.
Trouser leg packer
Note: The lateral force at the bottom hinge position can
compress packings and metal studs causing the leading
edge to drop. Before installing, ensure that studs are
secure and that fillings are dry.
� Re-hang door leaves.
Check and adjust for correct
gaps and operation of seals.
Compression seals should be
50% compressed along their
entire length. Blade and
brush contact seals should
overlap the opposing face by

Appendix 1
50%
compression
Note: Adjustment to the fit of
door leaves at the installation
stage should be deferred until
the site is completely dry when
the need for adjustment will be fully apparent and can be
remedied in a single operation:
- Adjustments made too early can result in excessive gaps
as the building dries.
- If possible, carry out adjustments by reducing or
increasing packing. Alternatively, pack out behind hinges
or recess them further.
- Only as a last resort should door leaf edges be trimmed,
this may necessitate replacement of seals and
repositioning of hardware affecting the quality and
integrity of the door.
6.2.3 Doorstops
� Fix loose doorstops after all adjustment. Fit to suit the
shape of the door leaf, permit an easy latching action
and ensure any seals are in correct contact with the door
face.
6.2.4 Stopping the fitting in gap
� Fill the fitting-in gap to suit fire, smoke or acoustic
requirements before fitting architraves or installing the
second half of split frames with integral architraves.
Architraves alone may fire stop gaps for FD30 doors but
do not prevent the leakage of cold smoke.

8 Specialist services
Because door installation and maintenance is a
specialised trade, it may be considered
advantageous to employ a specialist contractor to
carry out a planned routine combining the
inspection and corrective action procedures.
10.1 Protective measures
Planning the operation and protection of doors will
play an important part in the avoidance of damage
to the door installation. The following measures
will reduce the more predictable causes of
damage:
9 Priority actions
Priority should be given to:
� The continued correct operation of the doors.
� The preservation of operating gap sizes within the
range described in test or assessment reports relating
to the installed fire doors.
� The preservation or replacement of elements of the
door that may be subject to degradation through wear
or damage e.g.:
- Glass and hardware.
- Intumescent, acoustic and smoke seals.
- Applied finishes.
9.1 Pre-emptive inspection programme
The objective must be to pre-empt malfunction
and defects helped by a planned programme of
inspection.

11 Troubleshooting door malfunction
Malfunctions arise from a variety of causes. It is important that these be corrected promptly to minimise
damage and avoid any compromising of safety.
11.1 Binding
The most common malfunction is a loss of operating gaps that result in door leaves sticking or failing to close
correctly. It may be that the leading edge binds on the doorframe or at meeting edges of double leaf doors.
Often the bottom edge of a door will bind on the floor.
The causes of and suggested remedies for this can be:
