Class A Metal Chimney
Prior to installing the gas stove, ensure that the existing
chimney is functionally sound and clean.
• Have the chimney and adjacent structure inspected
and cleaned by qualified professionals. Hearth & Home
Technologies recommends that NFI or CSIA certified
professionals, or technicians under the direction of
certified professionals, conduct a minimum of a NFPA
211 Level 2 inspection of the chimney.
• Replace component parts of the chimney and fireplace
as specified by the professionals.

2. Measure the distance from the top of the chimney to the
bottom of the ceiling support box, add 3 in. (76mm) to
8.0
this measurement, and cut a section of 4 in. (101mm)
flex pipe to that length (the flex should be fully extended).
3. Connect the end of the flex pipe section to the underside
of the top adapter, using four sheet metal screws. See
Figure 3.20.
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 in. (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 onto
the top adapter. See Figure 3.21 and Figure 3.22.
