Step 5 - Measure and cut the excess
ex tube
From inside the attic, measure the distance from the top of the roof
opening to 6” below the opening in the ceiling. (g. 20) Remove the
ashing and dome assembly from the box but keep it in the cardboard
insert. With the unit upside down, pull up the ex tube to its most
extended position and mark the same distance as in the attic space.
(g. 21)
Begin cutting the excess material rst with a sharp utility knife (g. 22)
then when you get to the end of the cut use the wire cutters or tin snips
to cut through the wire. (g. 23)
Drop the ex tube into the roof opening (g. 24) then set the ashing as-
sembly into position and make a note of the outer footprint or mark with
chalk. (g. 25)

Step 6 - Remove the surrounding shingles
Once you know the outline of the ashing, remove the surrounding shingles with a pry bar. (g. 26) Composition asphalt shingles
can be installed in various sizes depending on your roof conguration so it is recommended that you remove the entire piece as
you nd it in the footprint of the SkylightTube ashing (g. 27) Make sure you remove enough shingles to allow the upper 2/3rds
of the ashing to make direct contact with the sheathing and roof underlayment (g. 28) Save all of the pieces you remove for
re-installation later.

Step 7 - Install the ashing assembly
When you are ready to install the ashing assembly, rst apply a bead of waterproof caulk or roong adhesive to the underside
of the ashing base. (g. 29) Re-install the ex tube into the roof opening and carefully place the top of the ashing underneath
the top-most row of shingles. (g. 30) Line up the bottom of the ashing with the shingle line and drive Screw A into the center
hole on the bottom as shown in (g. 31) This will allow you to ne tune the angle if necessary. Use standard 1.5” roong nails or
screws to secure the ashing in place (g. 32) There are 7 positions as shown in (g. 33)

ATTENTION: It is important to cut enough extra length of
tube to clear the ceiling opening by at least 6 inches.
