Vertical Damper Installation in  

a Masonry Wall

Actionair SmokeShield PTC - [AA/F10706]
Actionair FireShield - [AA/F10707]

Installation Method

1. 

Drill clearance holes in the damper flange at 150mm 

centres. 

2. 

Install the damper and fix through flange using fire 

rated fasteners, min ø4mm. 

3. 

Back fill between damper casing and wall, with mine

-

ral/stone wool and secure in place with angle retaining 

flanges, fixed in corners, or with Z shaped retaining 

flanges, to give the option of face fixing onto wall.  

Note: either angle or Z retaining flanges to be supplied 

by others.

4. Note: dampers supplied with cleats welded to top 

flange to assist with installation only.

5. Connecting ductwork omitted for clarity. Ductwork 

must be independently supported. There must be an 

appropriate break-away joint between the damper and 

connecting ductwork on both sides of assembly. Alu-

minium rivets or plastic cleats, clips, clamps and bolts 

etc. should be used for this, unless fire resisting duct-

work is being used where fire resisting fixings should 

be used. A minimum of 200 mm between fire dam

-

pers installed in separate ducts and 75 mm between 

fire damper and a construction element (wall/floor).

6. Alternative partition systems to those shown within 

this installation manual can be used if they have been

Description:

If  your proposed installation details

differ from that shown here, please

discuss this with the Building Control Authority

(BCA), referencing this documentation, 

associated fire tests, assessments, and other 

documentation shown below. Deviation from 

this drawing requires the approval of the 

relevant authority.

Installation Detail

Connecting ductwork omitted for clarity.  

Ductwork must be independently supported.  

There must be an appropriate break-away 

joint between the damper and connecting 

ductwork on both sides of assembly.  

Aluminium rivets or plastic cleats, clips, 

clamps and bolts etc.  should be used for this, 

unless fire resisting ductwork is being used 

where fire resisting fixings should be used.  A 

minimum of 200 mm between fire dampers 

installed in separate ducts and 75 mm 

between fire damper and a construction 

element (wall/floor).

IF YOUR PROPOSED

INSTALLATION DETAIL DIFFERS

FROM THAT SHOWN, YOU MUST

DISCUSS THIS WITH THE

BUILDING CONTROL AUTHORITY

(BCA), REFERENCING THIS

DOCUMENT AND THE

ASSOCIATED FIRE TESTS,

ASSESSMENTS AND OTHER

DOCUMENTS SHOWN BELOW.

DEVIATION FROM THIS DRAWING

REQUIRES THE APPROVAL OF

THE RELEVANT AUTHORITY.

EXPLANATION:

2 Hour fire, smoke rating, & 2 hour fire integrity.

The damper must be installed in accordance with the manufacturer's 

recommendations and HEVAC/HVCA publication HVC6/5/83 rev 1 

APRIL 2002.

This solution has been assessed by BRE to BS476 PT 20 for 2 hours 

and tested by BRE to BS-EN1366-2.

Acceptance of this solution must be sought by the system designer 

(In writing) from the appropriate LA prior to installation.

Requirements for access openings for inspection and cleaning 

purposes are provided in HVCA DW/144 specification for sheet metal 

ductwork.

Access provision must be allowed to permit jointing of ducts to fire 

damper. It may be necessary to install access doors on both sides of 

the partition so that the ducts can be fitted from inside the damper.

shown by test to have at least the same fire resistance 

when tested to BS EN 1364-1:1999 as is required  of 

the damper. If the partition system has been success-

fully tested without stone mineral wool it does not 

have to be used in practice when only considering the 

fire performance of the complete system. The mineral 

wool may still be needed for other reasons e.g. acous-

tic performance.
