FAILURE TO FOLLOW RECOMMENDED INSTALLATION PROCEDURES MAY VOID WARRANTY Check local building codes for glass requirements. • Please read instructions completely before beginning. • Deck and roofing felt should already be installed.
Sample installation on composition shingle roof: (Instructions 1 through 4 apply to all models.)

  1. To properly position skylight between trusses/ rafters, locate the roof opening from the under side 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.)

    1. measure distance between trusses/rafters and mark center point.

    2. to center skylight, measure one-half of ap propriate roof opening to each side of cen ter point and mark.

    3. 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:

    1. cut two 2 x 4's to fit the actual distance between trusses/rafters and nail into place. NOTE: Sizes 2525, 2549, 3333, 3349, 4949 Skip step "b" proceed to "c".

    2. cut two 2 x 4's to the exact length of the roof opening and nail to the trusses/rafters.

    3. if applicable, cut ceiling opening and build tunnel framing. (See "Light Tunnel Installation Instructions.")

    For CMG Model
    follow instructions 5 CMG     through 9 CMG

  5. CMG Build curb:

    1. Construct curb with 2 x 4's, 2 x 6's, etc. (depending on height desired or building code requirements). Curb should be minimum 3½" high. Be sure inside measurement of curb is the same as roof opening measurement.

    2. Secure curb to roof

  6. CMG Shingle roof up to bottom of curb.

  7. CMG Flash curb (sizes 2525, 2549, 3333, 3349, 4949 can be used with Sun-Tek's preformed, pre-cut Step Flash Kit with one-piece head and sill). Use galvanized sheet metal, aluminum, or copper. Metal should extend a minimum of 4" over shingles (on bottom side), then up sides of curb. Flashing should be flush with curb top.

  8. CMGShingle up sides and across the top.

  9. CMG Apply 1 " wide strip of sealant / mastic around entire curb top, starting ½" out from edge of roof opening. (if sealant is applied too close to roof opening, it may llooze" into the tunnel when the skylight is placed.)

  10. CMG Set skylight over opening. (Bottom edge of skylight is labeled ? this side must be placed on the bottom edge of roof opening to insure proper functioning of condensation wick.) Nail or screw in place through pre-drilled holes in side with 1¼" galvanized ringshank nails or weather- resistant screw

 
 

 

 
For VGC, FGC, FHP & TG MODELS:

  1. Shingle up roof to bottom of roof opening.

  2. Apply a 3½" wide strip of sealant/mastic around entire opening. (Sealant applied too close to roof opening may "ooze" into tunnel when skylight is set into place.)

  3. 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 the rink shanked galvanized roof nails provided or #8 x 1" pan head screws. The screws should be stainless steel, galvanized or zinc plated for resistance to corrosion. Use the pre-drilled holes for the fasteners.

    4. IMPORTANT: Bottom flange of skylight MUST go on top of shingles.

  4. Now shingle up sides and across top. Place shingles, as far in as possible, but be careful not to nail through skylight flange.

    5. DO NOT place any sealant on the top side of the skylight f lange! Sealant in this area will block the water diversion channels on the flange.

  5. Bottom flange will still be exposed: we recommend leaving it this way. If you decide to put a "false shingle" over it, be careful not to nail through skylight flange.

LIGHT TUNNEL INSTALLATION INSTRUCTIONS

For homes with an attic, it is necessary to build a tunnel between skylights and ceiling. The tunnel walls may be straight, or flared for extra light and architectural appeal. It's very easy to increase the tunnel size along the length of the ceiling joists. As long as no roof-supporting members are cut, no special framing is needed. While it is possible to flare the tunnel in all directions, if support members are cut, special framing will be required for structural support. In this case you must consult a qualified building professional to insure proper and safe results.

  1. After roof and ceiling openings have been framed, measure distance (at each corner of roof opening) between rafter/truss and ceiling joist.
  2. Using these four measurements, cut 2 x 4 lumber for verticle support members (two per corner).
  3. In each corner, nail vertical support members into place at right angles to each other.
  4. Measure, cut, and nail tunnel walls into place. Suggestions for lining tunnel:
    • use drywall, tape corners, and paint white using regular or texture paint. (Texture paint alone will hide and fill untaped joints
    • but in time, cracks may appear in corners.)
    • use prefinished paneling with molding in corners.
    • line the tunnel with cedar, pine, or a wood to coordinate with your decor.
    • for special effects, try painting the tunnel a striking accent color, or use mirrors or wallpaper on tunnel walls.
  5. Caulk the slight gap between the tunnel walls and skylight base.
  6. Finish off tunnel at ceiling with molding, or blend edges into ceiling with texture paint.
  7. Be sure to wrap the exterior of the tunnel with insulation for energy savings.
