FD-C Damper Installation, Operating & Maintenance Instructions
1. Storage
1.1
Dampers received on site should be stored in a purpose made storage area, where they can be protected
from moisture, dust and impact damage until required. Dampers are designed for installation within internal
normal dry filtered H&V systems.
2.
Health and Safety
2.1
Only competent personnel may carry out the work outlined in this document.
2.2
Wear appropriate Personal Protective Equipment as required for safe working conditions and as site rules
dictate.
2.3
Do not introduce fingers across the open blade or near to the spring loaded handle when releasing.
2.4
Where dampers are only accessible with the need for additional elevation, any equipment used should be done
so with due consideration to the Work at Height regulations 2005 and current site rules.
3. Important
3.1 These instructions should be read in their entirety before commencing work. The installer must be familiar with
the fire separating element construction detail that is produced by that particular manufacturer
, and the “as
tested
” damper installation method, as appropriate for that fire separation barrier.
3.2 Do not over-tighten Fusible Link (FL). Do not force handle when FL assembly is set. Refer to section s 10 and 11
for testing.
3.3 Check internally that any debris has been removed and ductwork is connected. If set and locked open before
installation, rough handling of the casing on larger sizes can cause the fusible link mechanism to actuate and
close the damper. For existing dry walls
– When cutting the opening for damper, and (partial) removal of stud is
unavoidable, ensure the structure is sufficiently supported to conform to design specification .
3.4 Dry wall openings must be lined. Please see figure 1.
3.5
Ensure that appropriate ‘fire-rated’ plasterboard is used throughout the construction of drywall partitions that
need to act as fire-barriers. Ductwork to be fitted and connected in accordance with DW 144 / DW145.
Aluminium rivets should be used (to act as breakaway-joint). If fire resisting ductwork is being fitted to the
dampers use the appropriate tested fire resisting fastenings. The use of Tec Screws is not recommended.
3.6 In accordance with TR/19 and B&ESA DW144 and DW145 access doors/panels/flexi-duct should be fitted
adjacent to the damper to allow commissioning, servicing and cleaning. Access doors should not be obstructed.
3.7 All installations are subject to local Building Control Approval (BCA). Tested Installations are detailed here in. If
the proposed installation deviates to that shown, acceptance from BCA should be sought before proceeding.
3.8 Refer to main product brochure for full details and specification.
3.9 Where more than one duct penetrates a wall or floor, adjacent fire damper a ssemblies should be separated by
a structural element with a minimum width of 200mm (to comply with BS EN1366 -2
. Sec’n 13.6), Exceptions to
this are Ablative Batt penetration installations that also allows for overlapping plates.
4. Equipment required
4.1
Equipment and tools will vary dependent upon the fire barrier construction that the damper is being installed
within. Standard equipment that are normally used for the building of the particular bar rier should suffice.
4.2
Access-equipment as necessary (steps pr platforms).
4.3
Cordless drill and various dia. drill bits / drivers to suit Installation Plate fixings, and duct connection fixings.
