TOOLS & PARTS
1
If you have an angled installation you will need to 
twist your Bottom Adjustable Tube so it lines up with 
the Top Adjustable Tube above. (Be sure you have 
removed the protective film.)
2
Measure distance from the top of Roof Flashing to 
ceiling (See illustration) to determine proper trimming 
of length of tubes. Refer to “Tube Length Chart” in 
Section 8 for cutting recommendations if you need to 
shorten the tubes.
3
Slide Bottom Adjustable Tube over the outside of Top 
Adjustable Tube.

Tape ALL seams securely with Foil Tape to keep dust, 
moisture, and insects out of the tube.

At this point, if you purchased a dimmer or 
combo kit, this is where you reference the 
dimmer instructions, packaged with the 
dimmer unit.
IMPORTANT
Gently set the Bottom Adjustable Tube ange down 
on the trim ring. Do not snap in place at this time.
Now you can push down to lock the Bottom 
Adjustable Tube securely into the lock tabs of the 
ceiling trim ring.
It is easier if 2 people work/turn the tube in opposite 
directions to angle the tube as needed.

The vertical seam of the reflective tube should point to 
the East or West to avoid irregular light patterns in your 
room.
