Installation, Operation and Maintenance Instructions
Due to continuing research, Greenheck reserves the right to change specifications without notice.
SAFEtY WARnIng:Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.
WARRAntYGreenheck warrants this equipment to be free from defects in material and workmanship for a period of one yearfromthepurchasedate.Anyunitsorpartswhichprove to be defective during the warranty period will be repaired or replaced at our option. Greenheck shall not be liable for damages resulting from misapplication or misuse of its products. Greenheck will not be responsible for any installation or removal costs. Greenheck will not be responsible for any service work or backcharges without prior written authorization.
Pre-Installation guidelinesThe basic intent of a proper installation is to secure the fire damper in, not to, the opening in such a manner as to prevent distortion and disruption of damper operation. This is accomplished by allowing the fire damper in rated separation openings to expand and for the connecting duct to separate in the event of the collapse of the hanging system. The following items will aid in completing the damper installation in a timely and effective manner.
1. Check the schedules for proper damper locations within the building. Visually inspect the damper for damage and verify that the fusible link is in place or has not separated. If fusible link is not present or has separated, replace link. Never install a fire damper without the proper UL approved fusible link in place. (Fusible link is standard controloption.Anelectriclinkmayhavebeenprovided.)
2. Lift or handle damper using sleeve or frame.3. Install damper accordingly to comply with manufacturer’s appropriate UL procedure file number.
4. Dampermustbeinstalledintoductoropeningsquareandfreeoftwistorothermisalignment.Dampermustnotbesqueezed or stretched into duct or opening.
5. Damper must be kept clean and protected from dirt, dust and other foreign materials prior to and after installation. Examplesofsuchforeignmaterialsinclude,butarenotlimitedto:

7. Caulking is not necessary, nor is it allowed, between the damper sleeve and the wall or floor opening (annular space). However, caulking may be applied to the retaining angles.
8. ACCESS:Suitableaccess(suchthatfusiblelinkscanbechanged)mustbeprovidedfordamperinspectionandservicing. Where it is not possible to achieve sufficient size access, it will be necessary to install a removable sectionofduct.(RefertoNFPA90A).

These instructions apply to 11/2 hour rated fire dampers mounted in masonry, block or stud walls and concrete floors. Specific requirements in these instructions are mandatory.

note: Fire dampers are manufactured and labelled for either vertical or horizontal installation. The dampers must be installed in accordance with the labelling.
1. no ADDItIonAL SLEEvES ARE REQUIRED The fire damper extended frame is an approved sleeve
and can be properly installed without the need for a supplemental field installed sleeve. Damper frame shall extendamaximumof6in.(152mm)beyondthewallorfloor opening on each side.

Fire damper assemblies expand during periods of intense heat. Therefore, it is essential that openings in walls or floors be larger than the fire damper assembly toallowforthisexpansion.Minimumclearancesrequired between the outside of fire damper sleeve assemblies and wall/floor openings are:

•Retaininganglesshouldnotbefastenedtothewall/floor material. The angles should only sandwich the wall/floor and allow for damper expansion during periods of intense heat.

Installation for Steel Stud Connection (SSC) option
6
1. no ADDItIonAL SLEEvES oR AngLES ARE REQUIRED
The fire damper extended frame is an approved sleeve and the Steel Stud Connection (SSC) Option allows fastening of the fire damper sleeve directly to the wall's steel stud framing. Damper frame shall extend amaximumof6in.(152mm)beyondthewallopeningoneitherside.MaximumsizefiredamperthatmaybeinstalledusingthisSSCoptionis36in.Wx36in.H(914mmx914mm).
2. InStALLAtIon Fire damper with SSC option must be in place before
the wall is constructed or it can be installed as the wall is being constructed. Wall opening is framed around the fire damper before sheet rock or other wall board material is applied to the steel studs. This installation provides appropriate protection for duct penetrations in fire resistant wall construction using steel studs with a fire resistance rating less than 3 hours. The following wall design numbers (as detailed in the UL Fire Resistance Directory) are appropriate for fire damper installations using this SSC option:

larger than the OD of the fire damper's extended frame (sleeve) using the same metal studs and techniques required by the wall design per the UL Fire Resistance Directory. Open side of the steel stud channels shall face the fire damper and encompass the damper's retaining bar.

Damper maintenanceDampersshallbemaintained,cycled,andtestedinintervalsasstatedinthelatesteditionsofNFPA90A,92A,andUL864unlesslocalcodesrequiremorefrequentinspections.Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use mild detergents or solvents. If lubrication is desired, do not use oil-based lubricants or any other lubricants that attract contaminant’s such as dust.
Damper trouble ShootingThe following is a cause and correction list for common concerns with the dampers.
Item Description
1 FD150X fire damper with SSC option
2 Steel stud wall (see UL Fire Resistance Directory for specifc details)
3 Steel stud frame around opening in wall
4 Duct connection (see section 6)
5 Wallboard (see UL Fire Resistance Directory for specific details)
6 Fasteners (see UL Fire Resistance Directory and Section 5)
Symptom Possible Cause Corrective Action
Damper does not fully open and/or fully close
Frame is 'racked' causing blades to bind on jamb Adjust frame such that it is square and plumb
Screws in damper linkage Locate screws and remove
