Instructions for Maxx Air Fan Install:
    ⁃ Mark the cutouts for the fans using the inside of the fan adapters/backing
      ⁃ Apply masking tape around the cutout marks to prevent scratching the paint with the jigsaw
        ⁃ Drill pilot holes for the jigsaw blade
          ⁃ Cut the holes with a thin metal cutting jigsaw blade
            ⁃ Dry fit the fans to ensure proper clearance
              ⁃ Deburr the fresh cut edges with a file or flap disk
                ⁃ Apply automotive primer to the exposed metal edges
                  ⁃ Install roof vent adapters and/or backing (if needed)
                    ⁃ Apply butyl tape along the bottom of the vent flanges
                      ⁃ Seat the vent flanges on the roof
                        ⁃ Drill pilot holes for flange screws
                          ⁃ Set the screws and hand-tighten with a screwdriver in a star pattern to finish
                            ⁃ Remove any excess butyl from edges
                              ⁃ Thoroughly clean the top of the flanges and the roof around it
                                ⁃ Apply a generous amount of Dicor Self-Leveling Lap Sealant to completely cover the edges including the screw heads
                                  ⁃ Set the fan in the roof and attach it using the 4 screws provided
