Illustration Key
The following safety rules apply to offset
installations. (The letters correspond with
letters above):
A. Height of the chimney measured from
the hearth to the chimney exit at top:
CR36L/R Series
Maximum: 90’0”
Minimum:
Without elbows 14’ 0”
With 2 elbows 15’ 0”
With 4 elbows 21’ 0”
B. Do not use more than four elbows per
chimney.
Attach the straps of the top elbows to a
structural framing member.
The first elbow of any pair does not have
straps.
C. The chimney cannot be more than 30°
from the vertical plane.
D. The maximum length of the angled run
of the total chimney system is 20 feet. (G
plus H cannot exceed 20 feet)
E. A chimney support (Model SKCS8) is
required every 6 feet of angled run of
chimney. Chimney supports are required
at 30 feet and 60 feet of chimney height
above the hearth also.
Determine the offset distance of your chim
-
ney arrangement from the centerline of the
fireplace to the centerline of the chimney
where it is to pass through the first ceiling.
NOTE: This offset distance may not be your
full offset distance. See Examples 2 and 3.
