horizontal mount dampers in non-concrete barrier
CFS, VFD, FD, FSD series fire and fire-smoke dampers
Figure 1
General
The following supplement provides basic assembly installation instruc-
tions for the 11/2 hour rated fire dampers, combination fire smoke
dampers and CFS Series ceiling fire smoke dampers when mounted
horizontally in UL Design I503. UL Design I503 is a 2 hour fire rated
horizontal barrier made from steel studs and gypsum board. Load is
limited to the dead weight of the assembly. Installation applies for
horizontal mount dampers up to maximum size 48"x 48"(1219 x 1219).
Single section size for each model may be different and is limited to the
maximum size in the product specifications.
Clearance
To make installation of the damper assembly into the floor opening easier, clearance between the damper sleeve and floor opening is recommended.
However there is no minimum clearance requirement between the floor opening and damper sleeve.
Installation Guidelines
Pottorff dampers are designed to be trouble and hassle free under normal operation. The intent of a proper installation is to secure the damper assembly
into the opening in such a manner as to prevent distortion and disruption of damper operation. The following items will aid in completing the damper
installation:
A. Retaining angles 20 gauge (1) minimum must be used to install the damper assembly into the floor opening. The leg of the retaining angle on the
damper sleeve shall be a minimum 11/4" (32) and the leg of the retaining angle on the floor shall be long enough to overlap the floor by 1" (25) minimum
and cover the clearance space between sleeve and floor opening.

or maintenance can cause property damage or injury.
B. Retaining angles shall be attached to the sleeve using one of the following connections:
1. tack or spot welds
2. 3/16" (4.8) diameter steel rivets
3. #10 sheet metal screws
4. 1/4" (6)nuts and bolts
Two connections minimum are required and shall be at a maximum 2" (51) from the corners and at maximum 6" (152)on center.
C. Retaining angles shall be attached to the floor on each side with minimum 2 self-drilling Type S #10 steel screws 17/8" (48)long, spaced 8" (203)
maximum on center and maximum 6"(152) from the corners.
D. Retaining angles are required to be installed above the floor and are optional below the floor.

Information is subject to change without notice or obligation.NOTE:Dimensions in parentheses ( ) are millimeters.Fire Dampers IIFDO&M(1/1) May 2008fire damperoperation and maintenance instructions
Dampers do not typically require maintenance provided they are kept clean and dry. All moving parts are self-lubricating and additional lubrication is not
required. If additional lubrication of multi-blade damper axle bearings, jackshaft bearings or jamb seals is desired, use a silicone or dry graphic lubricant.
Do not use petroleum-based lubricants or other lubricants that attract contaminants and collect dust.
Regular inspection and maintenance is essential to ensure that life-safety systems will perform as intended during emergencies. Dampers shall be cycled
and tested in accordance with NFPA 90 recommendations and local codes.
Maintenance
Simulated Fire Closure
• Non-Spring Assisted DampersOperate the damper by removing the fusible link (or by ‘melting’ the fusible link with a heat source) and allowing the blades to drop or close naturally.
CAUTION - Avoid injury - keep clear of blade travel path.Lift the blade package to the top of the damper to reopen and replace the fusible link.
Take care not to rack, deform or damage the blades while reopening.
• Dynamic Rated OR Spring Assisted DampersDue to spring assisted closure force, removing the fusible link is NOT recommended as a means of closure testing. Instead, when testing is required,
‘melt’ the fusible link with an appropriate heat source and allow the blades to close automatically. CAUTION - Avoid injury - Keep clear of blade
travel path.Lift the blade package to the top of the damper to reopen and replace the fusible link. Take care not to rack, deform or damage the
blades when reopening.
Reopening Spring Assisted OR Dynamic Rated Fire Dampers may be very difficult and in some cases impossible.If the damper is deemed
impossible or impractical to test or reopen, then a thorough examination of the blade travel path is required to insure that nothing will prevent
the damper from closing. Common obstructions include: retaining angle installation screws, racked damper frames, construction debris and
contaminants.
CAUTION - Testing Spring Assisted OR Dynamic Rated Fire Dampers under airflow conditions is
not recommended and may severely damage or destroy duct work.
Operational Testing
Troubleshooting Guide
Problem
Damper does not open and/or
close fully
Fusible link is separated
Installation screws interfering with
damper blade or linkage travel
Frame is ‘racked’ causing blades to
bind
Contaminants on damper
Excessive heat Replace link.
Note:If the damper is installed near a heat source
(heat exchanger, burner, furnace, etc.) higher
temperature links may be required to prevent
unwanted closure.
Inspect and remove interfering screws or debris
Adjust frame to be square and plumb
Clean with compressed air, mild detergent or mild
non-petroleum based solvent

the angles under the drywall, the fasteners must be a min. 1/2" long. For metal stud and the angles over the drywall the fastener must be a min. 1/2"
longer than the thickness of the drywall. i.e. if the partition has one layer of 5/8" drywall on the attachment side, the screws must be 1/2" + 5/8" = 1-3/8"
long. For wood stud openings, the min. length is 1-1/2" longer than the thickness of drywall on the attachment side. For concrete or masonry openings,
the anchors must be for min. No. 10 fasteners- screws or bolts. In lieu of masonry anchors and bolts/screws, self-tapping masonry screws can be used.
The fasteners in the partition should be located such that they are 1/2" below the top of the 1-1/2" flange of the retaining angles. Fasteners in the partition
should be spaced 12" o.c. max. A minimum of two connections per side, top and bottom. A minimum 3/4" 20 gauge (19 1)flange termination may
be used in lieu of mounting angles. Refer to Sleeve Termination Supplemental Installation Instructions and Framing for Fire Dampers for further details.
Ensure that attachment device does not interfere with the operation of the damper and the free movement of the damper blades. Note: If optional seal-
ing between the retaining angle (or flange) leg and the surface of the partition, wall, or floor, and/or between the retaining angle leg and the surface of
the damper sleeve is required, the following sealants may be used: Dow Corning 732 or DOWSIL 732 or GE RTV 108 or SCS 1201 RTV. These
sealants should be applied such that they do not intrude into the annular space between the outside surface of the damper sleeve and the opening of
the partition, wall, or floor, into which the damper/sleeve is being installed.LIS T IN
