PLANNING FOR SUCCESSFUL
INSTALLATION
When installing the ventilation fan in a new
construction site, install the main body of the fan and
duct work during the rough‑in construction of the
building. The grill should be installed after the finished
ceiling is in place.
When installing in existing construction, use the
dimensions on page 12 to determine the required hole
size for the ceiling. The grill edges should overlap the
finished ceiling.
NOTE: If installing in existing construction, you must
have access to space above and below the installation
location.
Do not install the ventilation fan in areas where the
duct work will require configurations as shown in the
following figure:
INSTALLATION OPTIONS
We recommend installing the ventilation fan by securing the main body of the fan against one ceiling joist and using the
header bars as necessary for support of the adjoining joist.
There are multiple installation configurations possible for this ventilation fan. Not all configurations are shown. If your
installation requires a variation other than those shown, consult with a licensed contractor to determine the best
installation for your project. If you are replacing an existing fan, ensure that the new grill will adequately cover the
existing opening.
