Sections. A maximum of 20 feet of Type B
Gas Vent may be supported. Note that the
Bucket Support must be installed prior to the
sheetrock.

assemble the Bucket Support and Brack-

the joist material as shown in Figure 14.
After the Support Bucket is in place, scribe
and cut out a hole in the sheet rock 1/8"
larger than the diameter of the Bucket, and
