Illustration Key
The following safety rules apply to
offset installations (letters correspond
with illustration above):
A. Height of the chimney is measured
from the hearth to the chimney exit.
CVR / STR Series
Maximum: 90'0"
Minimum:
Without Elbows 15'6"
With 2 Elbows* 17'6"
With 4 Elbows* 21' 0"
B. Do not use more than 4 elbows per
chimney.
Attach the straps of the return (top)
elbow to a structural framing member.
The offset (first) elbow of any pair does
not have straps.
FP720
C. The chimney cannot be more than 30˚
(45˚ in Canada) from the vertical plane in
any installation*.
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 (Models TCS8A or
11CS) is required every 6 feet of angled
run of chimney. Chimney supports are re
-
quired for every 30 feet and 60 feet (SK8
& CF11 pipe) of vertical chimney height
above the hearth.
Determine the offset distance of your
chimney 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.
