INSTALLATION INTO A CLASS A METAL
CHIMNEY (USA ONLY)
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" (102mm) 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 three sheet metal screws (Figure
19).
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" (3.3mm)
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
(Figures 20 and 21).
Step 5. Pull the flex pipe 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.
