clearance between the chimney and any
combustible materials. Interior enclosures
may be constructed with standard framing and
sheathed with sheetrock or plywood. Use a Wall
Strap or Stabilizer at least every 8 feet to maintain
a minimum of 2 inches of air space between the
chimney and combustible materials.
OFFSET ELBOW INSTALLATION
A 30° elbow (measured from the vertical) is
the largest that can be used in an offset. A
30° elbow may not be combined with another
elbow to make a steeper offset (e.g. two 30°
elbows are not allowed to be put together to
form a 60° elbow). Avoid elbows if possible. A
totally vertical chimney is more efficient. When
elbows are necessary to avoid obstructions
such as rafters, ridgepoles, or joists, you
are only allowed to use 1 pair of elbows in
any one chimney system. refer to Offset
Chart in Table 3 (page 14) to determine the
pipe sections needed for the offset desired.
horizontal runs of chimney violate building
code and are not allowed.
1. Attach Elbows: Attach elbow to Chimney
Section or other elbow by mating the male
and female ends with each other and
using the (4) sheet metal screws provided.
Attach one elbow to the Chimney Section
below, and align it for the offset. Determine
the required offset length and attach an
appropriate length (or lengths) of Chimney
Section(s) above the elbow. Attach the
second elbow above the Chimney Section to
complete the offset (Fig. 17).
2. Secure Offset: Use an elbow Strap to
secure the offset. Secure the elbow Strap's
band to chimney around the upper portion of
the top elbow, then tighten the nut and bolt
until the clamp is firm. Wrap the Elbow Strap
end over an adjacent joist or rafter and secure
it with at least two 8-penny nails or #8, 1-1/2"

screws. Add additional elbow Straps for each
section of chimney in the offset (Fig. 18).
every chimney section in the offset must be
supported. Do not add more Chimney Sections
until the elbows and the offset are supported.
Be sure that the chimney above the second
elbow remains vertical.
