2. Locate fan housing between joists so that bottom of heater
housing is even with the planned finished ceiling.
3. Use screws or nails (not provided) to secure hanger bars
to ceiling joists.
Using Side Mounting Tabs
1. Locate fan housing next to ceiling joist.
2. Use wood screws (not provided) through keyhole slots in
mounting tabs to loosely attach housing to ceiling joist.
3. Adjust housing so that it will be flush with the finished
ceiling. When housing is properly adjusted, tighten screw

EXISTING CONSTRUCTION
1. Determine desired location for ventilator.
2. Drill a small hole through the ceiling at the desired location
and stick a coat hanger or stiff wire through hole into attic
to help find the location from above.
3. Check the area above to make sure that wiring can be
installed and that the installation will not interfere with
existing electrical wiring.
4. From above, place the housing between ceiling joists at
the desired location. Using the housing as a template,
mark the area to be cut out along the bottom flange of the
housing.
5. After making the cutout, install the housing in the opening
using the hanger bars or mounting tabs as described
above. Make sure that the bottom of the housing is flush
