The following safety rules apply to offset
installations (letters correspond with il-
lustration above):
Height of the chimney is measured
from the hearth to the chimney exit.
WR/WC400 WR/WC500
Maximum: 90'0" 90'0"
Minimum:
Without Elbows 12' 6" 12' 6"
With 2 Elbows* 14' 6" 14' 6"
With 4 Elbows* 21' 0" 21' 0"
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.
IWF269
The chimney cannot be more than 30˚
(45˚ in Canada) from the vertical plane in
any installation*.
The maximum length of the angled run
of the chimney system is 20 feet. (G
plus H cannot exceed 20 feet.)
A chimney support (Model SKCS8)
is required every 6 feet of angled run of
chimney. Chimney supports are required
for every 30 feet and 60 feet (SK8 pipe)
or 20 feet and 40 feet (3-wall pipe) of ver-
tical 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.
This offset distance may not be
your full offset distance. See Examples 2
and 3.
