ROUND METAL DUCTWORK
1. Crimp the end of the branch duct.
2. Slip the end of the zone damper over the ductwork end. Use
a self--tapping sheet metal screw to secure.
3. Properly seal the joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with the actuator.
4. If dampers are applied in an unconditioned space, insulate
them using 1--1/2 inch to 2 inch insulation (See Fig. 2).

RECTANGULAR DUCTWORK
1. Make connections using S--lock and drives (See Fig. 3).
2. Properly seal the joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with the actuator.
3. If dampers are applied in an unconditioned space, insulate
them using 1--1/2 inch to 2 inch insulation (See Fig. 4).

ROUND FLEXIBLE DUCTWORK
1. Slip one end of the flexible ductwork over the zone damper
end (See Fig. 5).
2. Secure flexible duct to the zone damper using SMACNA or
other approved method.
3. Properly seal the joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with the actuator.
4. If dampers are applied in an unconditioned space, insulate
them using 1--1/2 inch to 2 inch insulation (See Fig. 6).

RECTANGULAR FIBROUS GLASS DUCTWORK
1. Insert one end of the zone damper into the fibrous glass
ductwork end approximately 2 to 3 inches (See Fig. 7).
2. Use the field supplied screws to secure the duct board to the
zone damper.
3. Properly seal the joint using duct tape, mastic, or other ap-
proved method. Do not allow mastic to come in contact
with the actuator.
4. If dampers are applied in an unconditioned space, insulate
them using 1--1/2 inch to 2 inch insulation (See Fig. 8).
