Installation Instructions
Installation Using AmeriVent Bucket Without
Hangers
1. Completely frame in (on all four sides) a properly
sized square opening. Select opening size so that
outside wall of AmeriVent Bucket (AB), 3-inch
through 8-inch, will contact framing at four sides.
See Figure 4.
2. Position AmeriVent Bucket through opening so that
bottom of Bucket will be flush with, or a little below,
bottom of ceiling.
3. Nail through sides of AmeriVent Bucket into framed-
in opening. Nail on all four sides, using a minimum
of two nails per side (8 nails total, minimum).
Bucket Connectors
The Bucket Connector (EBC), sizes 3-inch through 6-
inch, is used to make the connection of either AmeriVent
single-wall connector pipe, or AmeriVent Type B Gas
Vent, utilized as connector, through the bottom of the
AmeriVent Bucket.
1. The Bucket Connector is installed by positioning
it against the bottom of the AmeriVent Bucket, as
shown in Figure 5, with the mounting tabs
against the bottom of the bucket.
2. Position the inner wall of the Bucket Connector
inside the bottom end of the inner wall of the B
Vent section through the hole in the bottom of the
bucket. Attach the mounting tabs with sheet
metal screws.
3. Provide additional strapping or hangers for
connector offsets.
B. Firestop Supports
The Firestop (FS) and Support Bracket (SB) are
designed for use with Type B Gas Vent in sizes
3-inch diameter through 8-inch diameter.
When used by itself, the Firestop (FS) serves as a
firestop, while maintaining one-inch clearance to
combustibles from the outer wall of the Type B Gas
Vent. When the Firestop (FS) is used with the
Support Bracket (SB), this combination of parts
(FSP) serves as both a firestop as well as a support.
Each support is designed to support up to 20 feet of
vent pipe when installed as follows:
1. It is recommended that the Vent Pipe be
supported at least every other floor. The
distance between supports must not, in any
case, exceed 20 feet.
2. Frame in an opening providing one-inch
clearance to
AmeriVent Type
B Gas Vent.
See Figure 6
and Table 1.
