Installation
Step 1
Select a mounting location. When using a single
exhaust point, the damper should be installed directly
to the exhaust vent (see illustration 1). When using
multiple exhaust points, the damper can be located at
the "Y", "T" or collector box (see illustration 2). If
desired, additional dampers can be mounted at each
exhaust view point. Based on the plane of the airflow,
the damper should be mounted in a 180˚ radius above
a horizontal axis. Mounting the damper in an inverted
position may prevent the blades from closing com-
pletely. Preferred installation is vertical (illustration 1
is a vertical installation).
Step 2
Important: Dampers must always be installed so that
the airflow direction will open the butterfly blades. If
the damper is installed between the exhaust vent point
and the fan, the blades will open toward the fan. If the
damper is installed between the fan and the discharge
point, the blades will open away from the fan. Insert
the damper into the ducting at the selected locations.
The damper will easily fit inside wire helix type flexible
ducting. Secure using CB or FC clamps and/or duct
tape. When installing the damper into rigid type duct-
ing. FC clamps or duct tape should be used.
