Using Hanger Bars
Refer to Fig. 1
1. Insert hanger bars in slots provided in housing.

1. Locate heater 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 in slots to
secure housing.
EXISTING CONSTRUCTION
1. Determine desired location for heater.
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.
