Six Zone System Representational Layout
Installing Rectangular Dampers in
Metal Ductwork
1.
Cut out dimensions A and B as shown in Figure 2 by
using sheet metal snips.
NOTE:
Dimensions A and B are
listed in the Dimensional Examples table.
2.
Use foam insulation tape on the top and bottom of
the zone damper to prevent excessive air bypass. Also
check the cross emboss for excessive air bypass (see
Figure 2).
3.
Slide the zone damper into the ductwork making
sure no obstructions will interfere with damper blade
operation.
4.
Use the screws provided to mount the damper flange
to the ductwork. Four to six mounting holes are
provided as shown in Figure 3.
5.
Use drive cleats or regular duct mounting brackets to
attach ductwork to joist within six inches on both sides
of the damper (see Figure 3).
6.
Check damper blade operation for obstructions by
holding the manual release button and rotating the
damper shaft CCW (Open) and CW (Closed) 3 Wire
only as shown in Figure 4.
