INSTALLATION PROCEDURE
Prior to beginning your installation, please
verify what style connector pipe you have. You
may have "Locking Tab" style, or "Trim Ring"
style per
Fig.1
. These are the methods for
attaching your connector pipe to the support
box
(Fig.2).
Step 1.
Insert the adapter or Connector
section of pipe into the previously installed
Ceiling Support Box. Position it so the seams
are facing the wall, and the smooth side is
facing the room. For "Locking Tab" connectors,
push the pipe in firmly, until the locking notches
engage the top of the rim of the hole in the
support box. For "Trim Collar" style connector,
insert the pipe into the support box. Slide the
trim collar on and slide up to the support box,
until it is next to the pipe bead. Using the four
pre-punched holes in the trim collar as a guide,
drill 1/8" diameter holes in the support box, and
affix using the sheet metal screws provided.
It
is extremely important that the Support Box
be positioned so that the single wall pipe is
at least 18” from the combustible wall, and
also that the support box protrudes at least
2” below the ceiling.
Reposition the Support Box if necessary, to
meet these two requirements.
Step 2.
If you have "Locking Tab" style
connectors and you are installing the optional
Trim Collar, slide the Trim Collar upwards over
