Greenheck FD 150 Series, DFD 150 Series, FD-150X, FD-150V, FD-150H Installation Instructions Manual

...

Page 1

These instructions apply to 1 1⁄2 hour rated fire dampers mounted in masonry, block or stud walls and floors. Specific requirements in these instructions are mandatory. These instructions meet the requirements of UL 555. Installation shall comply with the requirements of NFPA 90A Standard for the Installation of Air Conditioning and Ventilating Systems. U.L. listing R13317, California State Fire Marshal listings 3225-981:102 and 32251241:101, and New York City BSA/MEA listing 260-91-M apply to these dampers.

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 extend a maximum of 6" beyond the wall or floor opening on each side.

2. CLEARANCES REQUIRED BETWEEN FIRE DAMPER SLEEVES AND WALL/FLOOR OPENINGS

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 to allow for this expansion. Minimum clearances required between the outside of fire damper sleeve assemblies and wall/floor openings are:

- Galvanized steel fire dampers and sleeves:

⁄8" per foot of damper width and height with a minimum clearance of 1⁄4". Recommended clearances, for width and/or height dimensions of:

1) 48” or less:

⁄2" clearance

2) More than 48” and 96” or less: 1” clearance

3) More than 96”: 11⁄2" clearance

These are total clearances (ignoring fastener heads) and do not need to be equally spaced around the damper. Refer to Section 3 and Figure 2 for additional installation considerations.

3.SECURING THE FIRE DAMPER TO WALL AND FLOOR OPENINGS.

Fire damper assemblies must be installed in wall and floor openings using retaining angles on each side of the wall or floor as described below:

- Retaining angles must be a minimum of 16 gauge steel and have a minimum of 1 1⁄2"x1 1⁄2" legs.

- Retaining angles must be attached to the damper using one or more of the following methods of attachment:

• tack or spot welds

• #10 sheetmetal screws

• 1/4" bolts and nuts

• 3/16

" steel pop rivets Attachments must be spaced a minimum of 6" on centers and a maximum of 2" from corners. The angles must be attached to all 4 sides of the sleeve with butt joints at each corner. A minimum of two attachments are required on each side, top and bottom. The angles need not be attached to each other at the corners.

- Retaining angles must completely cover the clearance space between the damper and the wall/floor opening, plus overlap the wall/floor a minimum of 1". This coverage includes all corners (see Figure 2).

- Retaining angles should not be fastened to the wall/floor material. The angles should only sandwich the wall/floor and allow for damper expansion during periods of intense heat.

- For grille installation on fire dampers up through 36" x 36" maximum, angle legs may be reversed and one leg inserted into the wall/floor opening provided the required clearance is maintained between angle leg fasteners and the wall/floor opening. Retaining angles used in conjunction with grille installations must be a minimum of 16 gauge steel and have a minimum of

⁄8" x 1 " legs (this is only applicable to fire dampers up through 36" x 36"; fire dampers larger than 36" x 36" will still require a minimum of 1 1⁄2" x 1 1⁄2" legs) (see Figure 3).

4. CONNECTING DUCTS TO THE FIRE DAMPER

All duct connections to FD 150X series extended frame dampers must be “breakaway” type connections. All connections shown on page 3 are considered breakaway. Factory furnished duct collars on types R &CR fire dampers are also considered breakaway (see Figure 1).

5. MULTIPLE SECTION FIRE DAMPERS

When multiple sections are shipped unassembled, installer shall fasten dampers together as described in Section 3. Table 1 at right shows maximum sizes for multiple section dampers.

Figure 3: Retaining angle installation when fire

damper is used in conjunction with a grille. (

⁄8" x 1" angles can be used on fire dampers

only up through 36" x 36".)

BREAKAWAY CONNECTIONS

Traditional Breakaway Style Transverse Joints

Transverse joints illustrated in Figure 4 have always been approved as breakaway connections. SMACNA testing has also approved the following variations as breakaway connections.

• Standing "S" joints can be applied with #10 sheet metal screws (through joint and duct) subject to the following limitations: Maximum 2 screws in each side and in bottom joint.

• Transverse joints illustrated can be applied as top and bottom joints with Drive Slip - side joints in duct heights up to 20 inches.

Round and Oval Duct Breakaway Connections

Round ducts connected to factory supplied Type R or CR damper collars may use #10 sheet metal screws as follows:

• Ducts 22" wide (or dia.) and smaller may use 3 screws.

• Ducts larger than 22" wide (or dia.) may use 5 screws.

Manufactured Flanged System Breakaway Connections

Flanged connection systems manufactured by Ductmate, Ward, and Nexus are approved as breakaway connections when installed as illustrated in Figure 5.

Proprietary Flange System Breakaway Connections

(TDC by Lockformer, TDF by Engle)

TDC and TDF systems are approved as breakaway connections when installed as described in the TDC or TDF addendum to the SMACNA Duct Construction Standards except the corners may not be bolted. Standard 6" metal clip may be used with spacing as shown in Figure 6.

Recommended Preparation of Openings in Wood and Metal Stud Walls

- Frame wall openings as shown in Figure 7.

- Double vertical studs are not required for openings 36" x 36" or smaller.

- Gypsum wall board must be fastened 12" on center to all stud and runner flanges surrounding opening (see Figure 8).

- All construction and fasteners must meet the requirements of the appropriate wall design. (See UL Fire Resistance Directory)
