General Information
“UL CLASSIFIED (see complete marking on
product)”
“UL CLASSIFIED to Canadian safety standards
(see complete marking on product)”
Standard 555C (Listing #R13446)
These installation instructions show recommended
installation procedures. These or other installation
methods may be followed subject to the approval of the
authority having jurisdiction.
The CRD-300WT series dampers are classified to
function as a heat barrier in air handling penetrations
through fire resistive membrane ceilings. They are
intended to maintain the fire resistive integrity of the
ceiling. They can only be installed in conjunction with
the SP fan models shown and cannot be installed
alone.
NOTE: Motors for fan models used in conjunction with
CRD shall be equipped with thermal cut-off fuse
control.
Receiving and Handling
Upon receiving dampers, check for both obvious
and hidden damage. If damage is found, record all
necessary information on the bill of lading and file
a claim with the final carrier. Check to be sure that
all parts of the shipment, including accessories, are
accounted for.
Dampers must be kept dry and clean. Indoor storage
and protection from dirt, dust and the weather is
highly recommended. Do not store at temperatures in
excess of 100°F (38°C).
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.
Damper Installation to a SP Fan
1. General: The fan/damper assemblies described in
these instructions, when installed as shown, provide
appropriate protection for approved floor/ceiling
designs rated up to one hour.
2. System Components: All system components
(ducts, duct drops, hanger wires, sleeves, and diffuser
pan) must be constructed of steel. The diffuser core
may be non-ferrous. Grilles may be non-metallic.
Flexible duct (if used) must be Class 1 or Class 0
type, bearing the UL listing mark. Maximum length of
flex duct shall not exceed 14 feet. The installations
and air devices shown in these instructions illustrate
general arrangement only. Installations must also
incorporate any specific requirements in the FRD (UL
Fire Resistance Directory). Note that both “Design
Information - General” and individual ceiling/floor or
ceiling/roof design listings apply.
3. Ceiling Penetrations: Ceiling penetration should
be located within ceiling tiles, panels, or gypsum
without necessitating cuts in the ceiling suspension
main runners, cross tees, or trusses. If required, a
maximum of one runner or cross tee may be cut
to enable proper damper location and installation.
Each cut end shall be supported by a minimum 12
SWG vertical hanger wire. a 1⁄2in. clearance must
be maintained between the air inlet/outlet and
the cut end of the runner or cross tee. Cutting of
wood trusses in combustible ceiling designs is not
permitted.

Ceiling Exhaust Fan Installation
1. Open package containing Ceiling Radiation Damper
(CRD), plaster flange and sleeve. Ensure tabs on
sleeve are folded over damper frame.
2. Using the (4) Tinnerman U-Clips provided, secure
the CRD to the sleeve aligning the Tinnerman clips
with the 0.25” holes on the sleeve. Position each
Tinnerman U-Clip such that the retaining side is
located on the exterior of the damper frame.
3. Position the CRD-300WT on the SP-AP Fan
Assembly so that the wire chase on the CRD is
located to the right of the fan’s junction box.
4. Install CRD-300WT onto the SP-AP Fan Assembly
using the (4) screws & lock nuts supplied. Locate
screw heads on the same side as the damper.
5. Next, install (4) 2” x 4” wood boards vertically to the
Truss Assembly 12” OC for mounting the SP-AP fan
assembly.
6. Using the height dimension of 3.625” (distance from
bottom edge of installation bracket to edge of CRD
to be flush drywall, see figure 2), measure and mark
the 2” x 4” wood boards where bottom edge of the
installation bracket is to be installed.
7. Secure one side of the SP-AP Installation bracket
assembly by fastening (2) captured self-tapping
screws to the 2” x 4” woods boards referencing the
mark made in step 6.
8. Extend the SP-AP Installation Bracket to the
required distance referencing marks made in Step 6.
Secure using (2) captured self-tapping screws.
9. Mount adapter to the expandable mounting bracket
using (2) self-tapping screws provided tapped to
duct adapter.

10. Push Fan/CRD Assembly into the mounting bracket/
adapter until it engages into the duct adapter.
Secure the fan body by using the three remaining
(1.25”) self-tapping screws provided tapped to duct
adapter.
11. Refer to the fan IOM for wiring.
12. Cut a 10.5” square hole in the gypsum board for the
fan/CRD assembly. Install ceiling gypsum board.
13. Secure the plaster flange onto the fan/CRD
assembly by fastening the (4) self-tapping screws
provided into the Tinnerman clips installed in step 2.
14. Mount one side of the grille by inserting the grille
springs into the slot on the plaster flange located on
the wiring side of the fan.
15. Install the wire retaining bracket with the remaining
(1) self-tapping screw.
a. When using a grille without light or motion sensor
align the flat of the wire retaining bracket with the
wire chase.
b. If using a lighted grille and/or motion sensor,
plug in the Light and/or motion sensor into
receptacle(s) in the fan housing. Install the wire
retaining bracket around the wires aligned with
the wire chase.
CAUTION
Ensure all wires are clear of the damper operation.
16. Insert the other grille spring into the slot on the
plaster flange opposite the one previously installed.
Push grille into place tight to the gypsum board.

Damper Maintenance
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 for components such as axle bearings,
jackshaft bearings and jamb seals, do not use oil-
based lubricants or any other lubricants that attract
contaminants such as dust.
Damper Troubleshooting
The following is a possible cause and correction list for common concerns with the dampers.
Symptom Possible Cause Corrective Action
Damper does
not fully open
and/or close
Frame is 'racked' causing blades to bind on jamb seals Adjust frame such that it is square and plumb
Screws in damper linkage Damper installed too far into wall. Move out
to line as designated on damper label
Contaminants on damper Clean with a non-oil based solvent (see
Damper Maintenance)
Link separated Heat Replace link
