B. Rectangular Metal Duct Work
1. Make connections using S-lock and drives. (See Fig. 3.)
2. Properly seal joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with actuator.
3. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check
your local codes.) (See Fig. 4.)
NOTE: All zone dampers and duct work must be properly
supported according to local codes or SMACNA standards.
C. Round Flexible Duct Work
1. Slip 1 end of flexible duct work over 1 end of zone damper.
(See Fig. 5.)
2. Secure flexible duct to zone damper using SMACNA or
other approved method.
3. Properly seal joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with actuator.
4. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check
your local codes.) (See Fig. 6.)
NOTE: All zone dampers and duct work must be properly
supported according to local codes or SMACNA standards.
D. Rectangular Fibrous Glass Duct Work
1. Insert 1 end of zone damper into 1 end of fibrous glass duct
work approximately 2 to 3 in. (See Fig. 7.)
2. Screw field-supplied screws and tabs into zone damper.
3. Properly seal joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with actuator.
4. Insulate damper using 1-1/2 in. to 2-in. insulation. (Check
your local codes.) (See Fig. 8.)
