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
D. Install the Termination Cap
• For installations utilizing a 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 30.1 on page 30.
• Install the chimney sections up through the chase
enclosure. When using a Round Termination Cap, the
uppermost top section of pipe must extend 6 in. (152 mm)
above the top of the flashing collar to allow installation of
the storm collar and termination cap. See Figure 29.3.
C. 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 29.1.
• All seams must be caulked to prevent leaks.
• A chase installation must use a chase top. Chase tops are
available from your Quadra-Fire dealer or may be field
constructed.
• Attach the chase top to the top of the chase.
Fire Risk
• Never install a single wall slip section or
smoke-pipe in a chase structure.
The higher temperature of this single wall
pipe may radiate sufficient heat to combus-
tible chase materials to cause a fire.
WARNING
Figure 29.2
Framing to top of chase must be constructed to support
service persons, snow load, etc. Maintain 2 in. (51 mm)
clearance to combustibles. Top of framing should be
sheeted with plywood particle board. See Figure 29.2.
