1. **Warning: Cut out drywall to the dimensions of the Grille
and not to the dimensions of the metal damper box.
From inside the attic at your predetermined location drill two holes at the edge of the joist
approximately 12 inches apart.
From inside the home use the two newly drilled holes as a guide to align the inner edge of the
grill and outline with a pencil.
Using a drywall saw or similar tool, cut out the drywall. (Note: be sure to secure the
drywall with one hand while cutting to prevent the drywall from falling or tearing
away.)
