B. Chase Top
A metal chase top is required to seal the top of the chase around the chimney pipe. The top should include a turn- down and drip edge to prevent water from seeping into the chase. Provide a 1/8 in. (3 mm) gap around the flue pipe and slope the top downward away from the penetration. See Figure 6.4.
