-
Read the instructions completely,
making sure that you have all of the tools needed to finish the job.
-
Determine where
in the room you want the light from the Sun-Tek Tube to shine. (Hint: for best results,
always try to center the light source in the room.) For optimum light, place on
the south face slope of the roof, if possible, and try to avoid shaded areas.
Note: Do not cut holes until both ceiling and roof hole locations are
marked.
Marking and Cutting the Holes
-
Locate the center of the ceiling
hole and make sure it is free of any obstructions in the attic. One of the following
methods may be helpful:
Have an assistant in the attic while you tap on the ceiling to indicate
where the tube will be located. Minor adjustments may need to be made as a result of
obstructions that need to be avoided, such as framing members, AC ducts, etc. Using a
pencil, mark the location.
Or
Take measurements from landmarks such as AC registers, light fixtures,
etc. and transfer those measurements to the attic. Using a 3" drywall screw, screw it
through the drywall to mark the desired location.
-
Put "Easy Cut"
template over
the screw and place a pencil in the other hole, and draw a circle on the ceiling. Leave
the screw in the ceiling.
-
Using a plumb bob, find the
location on the underside of the roof that lies directly above the drywall screw…
that indicates the center of the ceiling hole. Mark that location with a pencil mark.
Using page titled "DETERMINING ROOF PITCH", determine which slope best
represents the roof where your tube is to be installed. Drop the mark for the roof hole
directly down the slope by the amount indicated for the slope of your roof. For example (See
Drawing 5A), if your roof is a 3:12 pitch, you would move the mark for the center of
roof hole 1 ½” down the slope of your roofline. Use the 3" drywall screw to
screw up through the roof.
Cutting the Hole in the Ceiling
-
Cut
hole opening in the drywall using a key hole or jig saw. Use the screw to hold the cut out
section.
Marking the Center Roof
-
Place the "Easy Cut"
template
over the screw that protrudes up through the roof and scratch out a circle using a nail or
screw and cut through shingle & felt. (See Drawing #7)
Cutting the Hole in the Roof
-
Using a key hole or jig saw, cut the hole in the roof.
Removing the Shingles
-
Using a pry bar, carefully remove enough shingles to allow the flange of
the tube to lie flat on the felt paper. The
Flange of the dome should sit on top of the shingle at the bottom of the opening,
therefore, do not remove it. Carefully pull
the nails or fasteners out of all the shingles that are being removed.
Be sure not
to damage the shingles, as they will be used again. Leave plastic covering on dome.
Assembly of Tube
-
Insert the roof elbow through the hole in the roof so that the flange of
the elbow is resting flat on the roofing felt. To help minimize adjustments during the assembly process, place the seam in the
elbow in the 12 o’clock position (top of the opening). If
a
gap between the elbow and the hole is visible, slide the elbow to the bottom of the opening and place the roof collar under the flange
from the top of the opening. (See Drawing
10A). Place the two roofing nails in the
roof collar to hold it in position. Remove
plastic protection sheet form inside the roof elbow.
-
Place a 3/8” diameter bead of STS1000 sealant (included) around the
opening on the roof set back from the edge 1 ¼”. Place a second 3/8” bead set back 1 ¼” from the first bead.
(See Drawing 11)
-
Place the dome over the opening with the “This Edge Down”
sticker to the bottom of the opening. Center
over the opening, and press into place. (See
Drawing 12) IMPORTANT: Bottom flange of skylight MUST go on top of shingles.
-
Fasten the dome to the roof using the screws provided.
Be sure not to over-tighten. A screw should be used in every installation hole
provided.
-
The shingles that have a curved cut in them should have the curve trimmed
¼” larger to allow for the thickness of the dome material.
(NOTE: Dry fit the shingles into position to
keep sealant from getting on the dome.) Take
plastic covering of dome.
-
Run a bead of STS 1000 sealant around the perimeter of the flange where it
touches the roof. Also, seal the head of
every installation screw. NOTE: USE OF ANY
SEALANT OTHER THAN STA 1000, VOIDS WARRANTY.
-
Replace the shingles from the bottom up.
Roofing nails are provided. CAUTION:
DO NOT PULL A NAIL THROUGH THE FLANGE OF THE DOME. The bottom flange of the dome can be covered with a shingle but
DO NOT seal
this shingle down to the top of the flange.
-
Push the interior elbow up through the ceiling hole (See Drawing 17).
From inside the attic, pull the elbow up so that
the flange is flush with the ceiling. Align
ceiling elbow seam with the seam in the roof elbow. Pull
a nailing strap snugly to a rafter and nail into place with 1 ¼” roofing nails.
Repeat with the second nailing strap. If a nailing position cannot be reached with the
nailing strap, an additional 2 x 4 may need to be added between the trusses.
Remove plastic protection sheet from inside the
ceiling elbow (See Drawing 17A).
-
Rotate both the ceiling and roof elbows so that they align with each
other. The elbows rotate best when handled
gently. REMINDER: ALL PLASTIC PROTECTION
SHOULD BE REMOVED BY THIS TIME. Fit
the straight connector on the outside of the elbows to confirm fit.
While holding the straight connector in position,
remove the backing on the double sided tape and press firmly to adhere the tube to itself.
-
Use the duct tape to seal all joints and seams in the tube assembly.
Sun-Tek Tube recommends for maximum thermal performance wrapping the tube with insulation to
reduce heat loss and condensation.
Interior Dome
-
Place the interior dome gasket around the edge of the interior dome.
-
Align the interior dome with the tabs on the interior tube, and fasten
screws as shown in Drawing 20. DO NOT
OVER-TIGHTEN. Snap the screw covers closed. The job is complete!
-
Enjoy the Natural Light!
Cleaning
-
Use
a mild glass cleaner and a clean sponge or soft cloth.
