5 Shingle up roof to bottom of roof opening.
6 Apply approved sealant in a 3” wide band around the entire opening. (Caulking: Apply 3 ⁄” beads
one inch apart or 3” x ⁄” butyl tape.)
7 Center skylight to cover all aluminum from inside exposure. Set skylight over opening.
The label “This Edge Down” should be at the bottom of the opening. This insures proper
functioning of the condensation wick. Fasten the skylight to the roof using #8 x 1” pan head screws (see fastener schedule). The screws
should be stainless steel, galvanized or zinc plated for resistance to corrosion. Use the pre-drilled holes for the fasteners. Place a large
bead of sealant at the joint between the ange and the roof deck. Also, seal the head of each fastener.

1 To properly position skylight between trusses/rafters, locate the roof opening from the underside
of the decking. (If this area is not accessible, locate the ceiling joists from inside the house, mark
opening in ceiling (a-c), and cut ceiling opening. Then follow steps below for roof opening.)
a) measure distance between trusses/rafters and mark center point.
b) to center skylight, measure one-half of appropriate roof opening to each side of center
point and mark.
c) using the side marks as a guide, mark corners by drilling holes or driving nails through roof.
2 Remove shingles 6 - 8” out from roof opening.
3 Cut roof opening (snap a chalkline from corner to corner, or draw line with a straightedge.)
4 Frame roof opening:
a) cut two 2 x 4’s to t the actual distance between trusses/rafters and nail into place. NOTE:
Size 2525, 2549, 3333, 3349, 4949 Skip step “b” proceed to “c”.
b) cut two 2 x 4’s to the exact length of the roof opening and nail to the trusses/rafters.
c) if applicable, cut ceiling opening and build tunnel framing. (See “Light Tunnel Installation
Instructions.”)
