NOTE:
Have the existing installation inspected by
a qualified chimney sweep or professional installer
prior to converting to direct vent. The existing
chimney system must be in serviceable condition
and functionally sound and clean.
Step 1.
Remove existing chimney cap.
Step 2.
Measure the distance from the top of the chimney
to the bottom of the ceiling support box, add 3”
(76mm) to this measurement, and cut a section of 4”
(101mm) flex pipe to that length (the flex should be
extended to its nominal length).
Step 3.
Connect the end of the flex pipe section to the
underside of the top adapter (SDV #985K, 986K or
987K), using four sheet metal screws
(Fig. 19)
.
VERTICAL INSTALLATION
Step 4.
Pass the flex pipe down through the center of the
chimney system, and center the top adapter on the
top of the chimney pipe. Drill four 1/8” (3mm) diameter
holes through the top adapter, and into the chimney
top. Ensure that you are drilling into the metal on
the chimney. Twist lock the high wind termination cap
(SDV #991) onto the top adapter
(Figs. 20 and 21)
.
Step 5.
Pull the flexpipe down through the ceiling support box,
until it protrudes approximately 3" (76mm). Connect
the flex pipe to the retro connector (SDV #909B), and
attach with sheet metal screws.
Step 6.
Push the flex pipe back up into the ceiling support box,
center the retro connector, and attach it to the support
box with sheet metal screws.
Step 7.
The connection between the appliance and the retro
connector may be completed with sections of direct
vent pipe.
