VERTICAL INSTALLATION, cont.

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” (75mm) to this measurement, and cut a section of 4” (100mm) 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).
