CARRABINE JOINERY LTD (FIREDOORS)

1. SURROUNDING STRUCTURE

Frame, support wall construction

The frames must be fixed back to stud partitions, blockwork, brickwork or concrete Walls, at centres not exceeding 500mm. And penetrate to a minimum depth of 40mm Timber sub frames may be incorporated as a solid packer between the opening in the Supporting constructions and the rear face of the frame member of the door set. The sub Frame must cover the full surface of the rear of frame member, and be continuous for the full door set height/width. The timber shall be of the same density and structural quality as that specified for the frame itself. The gap between sub frame/ finished opening plus frame, not to exceed 10mm, should be filled with non-combustible material and capped off with intumescent mastic or the inclusion of an intumescent strip on the reverse of the frame. 2. TIMBER FRAME (see note on back page) Frames and stops can be softwood or hardwood for FD30. Frames and stops must be hardwood for FD60. Specification can be south from our office. The rear of the frame has to be protected. Where sub frames/ extension linings are used, the joint between the main frame and the sub frame must not intrude into the plane of the door set height/ width. Where an integral architrave is used, the face of the door must not protrude beyond the face of the wall. Usually the rear of the frame is protected by the adjacent wall, without excessive gaps, and the frame does not project out from the wall. If not, special assessment will need to be sought. Stops Stops to be minimum 12mm wide, machined from solid or planted, pinned only, using 40mm steel pins. Head/Jamb Joint Mortise and Tenon, Butt Jointed or Mitred, head twice screwed to jambs. Architraves Architraves are optional and have no performance requirements.

Stops

Stops to be minimum 12mm wide, machined from solid or planted, pinned only, using 40mm steel pins.

Head/Jamb

Joint Mortise and Tenon, Butt Jointed or Mitred, head twice screwed to jambs.

Architraves

Architraves are optional and have no performance requirements.

3. HANGING LEAVES

Gaps

Doors should be hung to give and equal gap across the head and down both jambs, the gap not to exceed 4mm. The gap between the door and the frame should not exceed 4mm; the gap at the meeting stile should not exceed 4mm and the doors should not be proud of the frame reveal by more than 1mm. Smoke seals which require a larger gap should remain within tested tolerances.

4. GLAZING

On site cutting of apertures is NOT permissible. (Only by Carrabine Joinery)

5. IRONMONGERY (See also Note On Back Page) Large lock for ends and bolts require to be bedded on low pressure intumescent. Door closers should be supplied with intumescent gaskets, wherever applicable.

Take care with ironmongery as certain items and their fixings may not be compatible with Carrabine Joinery or other timber cored door constructions.

6. PRE INSTALLATION HANDLING & STORAGE

If storing finished doors, door sets and door kits, they should be protected from rain and sun, preferably in a ventilated building. Fire doors are for internal installation and should also be protected from exposure to excessive moisture and splashing by corrosive or staining materials. Store horizontally on 3 or more equally spaced bearers, away from floor or ground. Keep in wrappings as long as possible. Site environmental conditions should be within the following parameters: 40% to 60% RH and13°C to 21°C.

Protect Glazed Doors 

Use spacers between stored doors to prevent glazing beads from damage. 

Unlaquered Doors 

Should have a coat of seal applied as soon as possible. 

Laminate Faced Doors 

Refer to manufacturers guide on care and maintenance. 

Protect Facings 

Door assembly timber components that are to receive a clear finish, or veneered surfaces, should not be exposed to strong lights, daylight or uneven light during storage as this can cause differential fading. Cleaning Veneered Doors 

Clean veneered doors and panels by wiping with a damp cloth. Do 

………………Column Break………………not use abrasive or chemical cleaners if necessary, use a mild deter- gent solution. Smoke And Heat Activated Seals Heat activated seals and smoke seals can easily be damaged. When supplied separately, for fixing after installation of the door assembly, they should be kept wrapped in a dry, ventilated environment and be clearly identified. 

 7. METAL FRAMES 

Enquiries regarding aluminium frames may be addressed to Tech- nical Support by fax or Email at the contact numbers shown. Fixing & Sealing To Structural Openings Guidance for fixing door sets, and methods of providing an adequate fire resistant seal to the structural opening, is documented in BS8214: 1990 Code of practice for Fire door assemblies with non metallic leaves”. This 

should be referred to where necessary. 

8. Post installation 

Once the doorset has been securely fixed it should be checked for operation by opening and closing the door ensuring that it does not hit the frame at any point. It should be possible to secure the door by the latch with only a light pressure. The top and bottom compression bolts will be activated and en- gage when the lever handle is lifted. It should be possible to activate the centre deadbolt with the key. If the operation is not smooth then the fixings should be loosened and the 

frame adjusted re-secured and checked once more. Important: Any gaps between the frame and the wall must be seal as per overleaf 

9. Maintainace 

Fire doors are an important safety feature of any building in which people work or visit, as they offer resistance to the spread of fire and smoke limiting its effect. They are particu- larly important elements of fire protection on escape routes and as such, the Heads of Departments are to ensure regular checks of the fire doors on a premises and monitoring their condition for effective operation 

On Site Instructions 

These on site instructions refer only to fire doors manu- factured by Carrabine Joinery Fire doors. Otherwise, gen- eral application must comply with test requirements of individual suppliers. 

Handling and storage of Doors 

When you have made a selection of Carrabine Joinery Doors we are very keen that you then get the most value and benefit from our products. We take every care and attention to ensure that you receive our goods in perfect condition. However, as with most timber prod- ucts and furniture, care and attention need be exercised in on site storage and handling. To ensure that our products are in as good of condition on handover as the day they were delivered, we have pre- pared some points and guidelines which we hope you find of some assistance. 

• Doors should be stacked flat, raised off the floor on not less than three bearers on a level surface and protected by waterproof coverings on all sides. 
• Veneered doors should be stored so as no part is exposed to the light as this would result in fading and discoloration. 
• Doors for polishing should be handled carefully to avoid soil- ing. They should receive a first coat as soon as possible. 

• Doors should be handled using clean gloves to avoid finger marks. 
• On leaving our workshop, doors have a moisture content of between 8%-14%. This should suit the intended eventual use and all precautions to ensure that this remains the case should be taken. 
• As timber doors are hygroscopic they will absorb or lose mois- ture after leaving the factory if not properly protected. Care should be taken to ensure a relative humidity of between 40%-60%, and that the doors are maintained in a clean and dry environment while in storage, during installation and thereafter. Any variation of the above will cause the door to absorb or lose moisture – which will result in core telegraphing and shadowing. Furthermore, if moisture is not equal on each face of the door, it will cause distortion. 
• Doors should be ordered so that the period of storage on site before erection is kept to a minimum. The building program should be planned so that the period between the fitting of the door and occupation of the building is kept to a minimum. 
• Ensure that doors are not taken on site before the building is roofed and glazed. 

• If heating is to be introduced, it should be gradual and equal to all surfaces of the doors, otherwise serious distortion of the leaves can result. 

………………Column Break………………Heating should be switched on initially at low levels and gradually raised to the desired level over a period of time.
