We have a 2020 Tab 320s and are replacing our Fantastic Fan with a Maxxair Maxxfan Deluxe 7000K. The new fan is in place, wired in, and it works but we’re having trouble with the final step, attaching the garnish ring. We’re unable to screw it to the ceiling. It looks like there is aluminum framing around the opening. Do we need to drill pilot holes?
