pipe, which is exposed to the weather (Fig 10 & 11). Slide the Storm Collar down
over the chimney to the top of the Roof Flashing. Tighten and seal the Storm
Collar against the sealant. After installing sufficient Chimney Sections to meet
the height requirement (Fig 1), attach the Chimney Cap on top of the chimney by
holding the collar of the cap and twist locking it clockwise onto the chimney. Do
not hold the upper portion of the cap and twist, as this may damage the cap. The
Chimney Cap can be removed for chimney cleaning as described in the Chimney
Maintenance section of the instructions. Use an Extended Roof Brace if the
chimney extends more than 5 feet above the roof (Fig 13 & 14 on pg 14).

Enclosures:
Enclose chimneys where they pass through occupied spaces,
including closets. Always maintain at least a 2 inch clearance between the
chimney and any combustible materials. Interior enclosures may be constructed
with standard framing and sheathed with sheetrock or plywood. Use Wall
Brackets as needed to maintain a minimum of 2 inches of air space (clearance)
between the chimney and combustible materials.
OFFSET ELBOW INSTALLATION
Elbows are manufactured in 15° and 30° angles measured from the vertical. A 30°
Elbow is the largest that can be used in an offset. A 30° Elbow may
NOT
be combined
with a 15° Elbow to make a 45° offset. Avoid Elbows if possible, since a totally vertical
chimney is more efficient. When Elbows are necessary to avoid obstructions such as
rafters, ridgepoles, or joists, use
no more than two 30° offsets
in any one chimney
system.

Attach Elbows:
Attach Elbow to Chimney Section or other Elbow. Please note
that the female end of the elbows are not lanced, in order to ensure proper
alignment of the chimney system can be maintained. Locking bands are
included and must be used at all chimney joints. Attach one Elbow to the
