For installations utilizing a TR11T Round Telescoping Termination Cap, the uppermost chimney section must be below the top of the chase top, but not more than 14 -1/2 in. (368 mm) below the top of the chase top. Minimum overlap of chimney and termination cap must be 1-1/2 in. (38 mm). See Figure 6.6.

For installations utilizing an ST1175 Square Termination Cap the last chimney section must not be more than 4-1/2 in. (114 mm) below the chase top. See Figure 6.7.

For installations utilizing an TCT1175 Terra Cotta Cap the last chimney section must be between 7 in. (178 mm) below the chase top and 2 in. (51 mm) above. See Figure 6.8.
