Installation Instructions for
Converting a Factory-Built Metal
Chimney
1. Remove the existing chimney
cap.
2. Measure the distance from the
top end of the chimney to the
bottom of the ceiling support box,
add 3” to this measurement and
cut a section of 4” flex pipe to that
length (the flex should already be
extended to its nominal length).
3. Connect the end of the flex pipe
section to the underside of the
cap adapter you have selected
using three (3) sheet metal screws. (Figure 46)
4. Pass the flex pipe
down through the center
of the chimney system,
and center the adapter
on the top of the chimney
pipe. Drill four (4) 1/8”
diameter holes through
the adapter and into the
chimney top. Insure that
you are in fact, drilling
into the metal on the
chimney. Twist-lock the
termination cap (980,
991 or 930) onto the
adapter. (Figures. 47
and 48)
5. Pull the flex pipe down through
the ceiling support box, until it
protrudes approximately 3” (76
mm). Connect the flex pipe to
the retro connector by slipping it
into the 4
3
⁄
4
"(121 mm) diameter
sleeve on the top side of the
connector. Use three (3) sheet
metal screws to assemble these
two parts.
6. Push the flex pipe back up into
the ceiling support box, center
the retro connector and attach it
to the support box or decorative
sleeve for double wall solid
packed pipe, with the sheet metal screws furnished. The
holes in the retro connector are pre-punched. (Figure 49)
