Fig. 7—Insulated Rectangular Metal Ductwork
NOTE: All zone dampers and ductwork must be properly sup-
ported according to local codes or SMACNA standards.
NOTE: There should be a minimum of 4 ft between the zone
damper and the first branch duct if more than 1 branch duct is
downstream of the zone damper.
C. Round Flexible Ductwork
1. Slip 1 end of flexible ductwork over 1 end of zone damper.
(See Fig. 8.)
2. Secure the 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
