Instruction
12
Ensure the minimum ½-inch spacing and
perimeter ventilation requirements are met
as show in Figure 12. Secure the Chase Top
Collar Section to the eld-fabricated chase
top with sheet metal screws or rivets (Fig. 14).
Seal Chase Top Collar Section to chase top with
non-hardening waterproof sealant to ensure a
weather tight connection. Additional screening
as needed for eld-fabricated chase covers is
allowed. Additional ½-inch minimum spacers can
be eld-fabricated as needed out of 24 GA sheet
metal or other suitable non-combustible material.
Additional non-combustible structural supports
can be eld-fabricated to help support the chase
top ashing if needed, provided the air ventilation
requirements are maintained. Secure the Chase
Top Flashing to the chase with at least three
(3) screws or nails per side. When installed, the
bottom of the Chimney Cap must be at least 6
inches above the Chase Top Flashing (Fig. 15).
13. Finish Top: Apply a non-hardening
waterproof sealant around the chimney at the
point where the Storm Collar will meet the
chimney just above the Flashing (Fig. 15). Slide
the Storm Collar down over the chimney to the
top of the Flashing. The Storm Collar must be
installed 1-inch off the Chase Top Flashing to
provide proper ventilation (Fig. 15). Tighten the
bolts of the Storm Collar and seal the Storm
Collar against the Chimney with sealant. Be sure
Chimney and Offsets are properly supported.
Attach the Chimney Cap onto the top of the
chimney by setting the female end of the Cap
onto the male end of the last Chimney Section.
Secure the Cap by using four (4) sheet metal
screws provided (Fig. 16). Do not push down
from the top portion of the cap as this may
damage the cap. Push from the lower section
of the Cap if needed. The Chimney Cap can be
removed for chimney cleaning as described in the
Chimney Maintenance section of the instructions.
