Cap
Note: To protect against the effect of corrosion on those
parts exposed to the weather, the termination cap can be
painted with a rust-resistant paint.
Fire Risk
• The minimum overlap of cap to pipe
MUST be met or chimney may separate
from cap.
Separation allows sparks, heat and embers
to escape.
WARNING
C. Install the Termination Cap
• 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.
• Install the chimney sections up through the chase
enclosure. When using a TR11 Round Termination Cap,
the uppermost top section of pipe must extend 6 in.
(152 mm) above the top of the fl ashing collar to allow
installation of the storm collar and termination cap. See
Figure 6.5.
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 fl ue pipe
and slope the top downward away from the penetration. See
Figure 6.4.
• All seams must be caulked to prevent leaks.
• A chase installation must use a chase top. Chase tops
are available from your Heat & Glo dealer or may be fi eld
constructed.
• Attach the chase top to the top of the chase.
