Introduction
Advanced Air (UK) Ltd have been manufacturing a comprehensive range of fire dampers and fire smoke
dampers since 1975. We have always taken pride in our products and tested to the highest standards,
originally to BS476 and now more stringent testing to CE labelling under the Construction Product Regulation
which was introduced 1st July 2013.
All our fire, fire smoke and smoke control dampers have been tested to BS EN 1366-2 and BS EN 1366-10.
This is to cover a variety of installations used on sites today. Under CE labelling all dampers must follow the
Product Standards BS EN 15650 and BS EN 12101-8 which ensures the product is consistent and supplied to
the same specification and standard as tested. Any deviation or changes from the installations in this manual
would require the dampers to be subject to a new test or approval sought from Local Building Control.
In line with product standards we are pleased to oer this installation manual covering installation, operation
and maintenance instructions together with Health and Safety information. We have also included within this
manual an example of the Fire Damper Checklist DW145 Inspection and Handover Check Sheet which is to
be completed by the installer. A separate certificate is required per damper.
The installation contained in this manual cover most installation on site. However, there are still installation
which Advanced Air (UK) Ltd have not yet tested. We are continually reviewing requirements and continuously
developing the products. As additional installation tests are carried out and classified, installations will be
added to this manual, and the Declaration of Performance (DoP) updated accordingly.
Health and Safety
Any instruction contained within this manual must be undertaken by competent trained personnel. When
completing the installation standard PPE should be used, steel toe cap boots, hard hat, gloves, protective
eyewear along with any other specific site or material instructions.
The size and weight of dampers vary, and it may require two or more persons to safely handle and move
them. Do not lift the dampers by the blades or the actuator.
For the installation of dampers at high level, the correct lifting equipment shall be used in accordance with
the Work at Height Regulations 2005 and specific site rules.
All waste materials should be collected and disposed of defined by the suppliers.

Preparation
1 Ensure that the damper is kept
in a clean dry environment and
that there is no damage to the
damper.
2 Remove all the packaging
before installation.
3 Work out the opening size to be
cut using the adjacent table.
Installation sequence
4 The drywall will consist of two layers of 15mm plasterboard each side of steel studwork with an optional
50mm mineral wool insulation. The opening will be a letterbox construction with overlapping layers
of plasterboard with an opening clearance around the damper casing in line with the table above.
5 Two M10 drop rods shall be fitted on the side of the drywall to which the access side of the damper
will be positioned. These should be securely installed in line with the manufacturer’s fixing instructions
in a position to match the AFS rail.
6 The drop rods should have a nut screwed on for clamping the rail from above.
7 Slide the AFS rails on each side of the damper into the brackets and insert the “Z” piece into the
bracket slot pushing it up against the underside of the rail. Insert the 8mm bolt from above into the slot
through the “Z” piece fitting the nut until tight to secure the rail.
8 The damper should be mounted centrally in the opening with the access side flush with the wall, as
detailed in the drawing. The drop rods are to slide through the slots in the rail and a nut screwed on
to take the support of the damper rail. The damper must then be levelled and when in the correct
position the nut above the rail should be tightened against the rail.
9 The galvanised mild steel ductwork connecting to the damper spigots must overlap by up to 40mm,
leaving a minimum 10mm clearance for any duct expansion in a fire situation.
10 The galvanised mild steel ductwork connections must be sealed with an approved galvanised mild
steel ductwork sealer.
11 The connecting galvanised mild steel ductwork must be independently supported within one metre of
the connections and have been installed in accordance with DW144.
12 The gap between the damper and the wall opening will need filling with two layers of 50mm thick
140kg/m fire batt cut to an interference fit and pushed in to place. All cut edges must be sealed with
a fire batt sealant to BS EN 13501-2. A fire rated intumescent mastic to BS EN 13501-2 shall be applied
to each joint.
13 An access door should be fitted on the access side of the damper for inspection and maintenance of
the damper.
14 When the damper installation has been completed checks should be made to ensure the AFS rails are
secure and there is no movement, operation of the damper should be checked.

TESTED INSTALLATION METHOD SHOWN. DIFFERING INSTALLATION METHODS TO THIS MUST BE APPROVED BY THE BUILDING CONTROL AUTHORITY (BCA) BEFORE PROCEEDING.
SMOKE CONTROL  26SCD TWO HOUR REMOTE FROM WALL INLINE
Preparation
1 Work out the opening size to be cut 120mm larger than the
nominal duct width/height, at a tolerance of ±5mm (for example
a 1,000 x 1,000mm duct requires a 1,120 x 1,120mm opening).
Installation sequence
2 Drill and rivet at 150mm centres, the 50x50x5mm stiening flange
to the galvanised mild steel galvanised mild steel ductwork.
3 Pass the duct through the opening, so that the flange is
centralised in the wall.
4 Drop rod anchor points, and M10 drop rods to support the
galvanised mild steel galvanised mild steel ductwork, should be
positioned within 350mm of the wall, on both sides.
5 Install Unistrut to the drop rods with M10 fixings, and adjust to
that they fully support the weight of the galvanised mild steel
galvanised mild steel ductwork, using a spreader plate. The
position of the duct should be adjusted so that the stiening
flange is centralised in every axis.
6 Fill the wall opening around the duct with 85-115kg/m2mineral
wool insulation, on both sides of the wall.
7 Fit two layers of 200mm wide, 12.5mm thick plasterboard around
the damper, overlapping the joints, to form a pattress around
the galvanised mild steel galvanised mild steel ductwork on
both sides of the wall. The pattress must be axed with drywall
screws which bite into the steel stud channel at 150mm centres,
and sealed with a bead of intumescent acrylic sealant to BS EN
13501-2, which shall be applied to back of each pattress section
before it is fitted.
8 The damper is mounted to the duct using self tapping fixings, at
150mm centres. When the duct is slid over the damper spigot,
an overlap of up to 40mm is permitted, allowing for 10mm for
duct expansion.
9 Support the damper case using a single piece of Unistrut, hung
on M10 drop rods.
10 Galvanised mild steel ductwork and sealing of the duct should
be in accordance with DW144.
11 The damper operation should be checked to ensure that it fully
opens and closes.
12 When the damper installation has been completed, checks
should be made to ensure the installation is secure, and there is
no movement.

Installation sequence
1 Install drop rod anchor points, and M10 drop rods to support
the damper, using the AFS (Adjustable frame system). M10
drop rod lengths should be a maximum of 1,000mm in length.
Where longer lengths are required, the bottom 1,000mm of M10
drop rod should be joined to an M16 drop rod above for the
remainder of the length, using M16/M10 transition pieces.
2 Slide the AFS rails on each side of the damper into the brackets
and insert the “Z” piece into the bracket slot pushing it up against
the underside of the rail. Insert the 8mm bolt from above into the
slot through the “Z” piece fitting the nut until tight to secure the rail.
3 The drop rods are to slide through the slots in the rail and a nut
screwed on to take the support of the damper rail. The damper
must then be levelled, and when in the correct position the nut
above the rail should be tightened against the rail.
4 The damper is mounted to the duct using self tapping fixings,
at 150mm centres. When the damper is slid into the duct, an
overlap of up to 40mm is permitted, allowing for 10mm for duct
expansion.
5 The connecting galvanised mild steel ductwork must be
independently supported within one metre of the connections
and have been installed in accordance with DW144.
6 An access door should be fitted on the access side of the
damper for inspection and maintenance of the damper.
7 The damper operation should be checked to ensure that it fully
opens and closes.
8 When the damper installation has been completed checks
should be made to ensure the AFS rails are secure and there is
no movement, operation of the damper should be checked.
