BEFORE YOU START Check Ceiling Slope (Universal Mount) Consult the table below to make sure you have the appropriate downrod length for your ceiling slope. Universal Mount fans can be installed on flat or sloped ceilings with an angle no greater than 33° (approximately 8:12 roof pitch). For minimum clearance guidelines, consult the Important Safety Instructions booklet included with this installation guide.
