NOTE FOR STRAIGHT RUN CHIMNEYS:

Chimney support required at 25' chimney height.

NOTES FOR CHIMNEYS WITH ELBOW OFFSETS:

The length of the inclined portion of the chimney between elbows must not exceed 6 feet when unsupported, or 20 feet if the chimney is supported at 6 foot intervals using either metal support straps or an LCS chimney support.

The LCS chimney support when installed at a 30 degree angle will add 8" of rise and 4-5/8" of offset to the chimney height calculations.
