plate should close (horizontal position). When
the chain is released (no weight on the chain),
the damper should swing open (vertical
position).
3b. Lintel Hook: With the damper plate in
the closed (horizontal) position, determine
and mark the location for the Lintel Hook. The
Lintel Hook should be mounted in a position
so as to provide a small amount of tension in
the spring attached to the chain (Fig. 25). The
tension is needed to prevent the damper plate
from rattling when closed. Mount the Lintel
Hook to the masonry with the screws provided.
4. Attach Chimney: Attach the rst Chimney
Section onto the Anchor Plate by using the
sheet metal screws provided.
5. Finish Chimney: Install the rest of the
chimney as directed in the Ceiling Supported
Installation section, Steps 4 through 11.
Refer to Figure 1 and Table 4 for chimney
height requirements. Always maintain at least
2 inches of clearance to combustible materials,
and enclose the chimney where it passes
through occupied areas. The 2-inch clearance
is an air space; do not ll that clearance space
with any materials. Use a Wall Strap for every
four (4) feet of chimney height.
