be used in many applications when a
B-Vent connector is not required.
7. Elbows. When Elbows are re-
quired, strap the Pipe Sections and/or
Elbows in place using Wall Straps.
Support the offset so that the weight of
the offsetting pipe is not bearing down on
the elbows, as shown in Figure 10.
8. Tees and Wyes. Tees and Wyes
are used to combine connectors from 2
or more appliances into a common vent
as shown in Figures 2 and 3. A Tee
should be used in a through-the-wall
application, (Figure 11), as they have a removable Tee Cap (available as a
separate item) attached to the bottom. This Tee Cap may be removed in order
to inspect the system, or to clean out debris or collected condensate from the
common vent. Wall Straps should be used to support the vertical pipe as needed
to provide a secure installation. Wall Straps every four feet are recommended.
9. Enclosures. Any portion of the vent which passes through an occupied
area must be enclosed, to prevent accidental damage to the system, as well as
burns. Figure 1 (page 2) shows a
system which passes through an occu-
pied second floor. Simpson Dura-
Vent does not recommend installation
of B-Vent Pipe on the outside wall of
a building, particularly in cold cli-
mates. If it is necessary to do this,
enclose the outside portion of the sys-
tem in a chase, as shown in Figure 11.
It would be wise to consult the Local
Authority prior to construction. Note
that the enclosure requires an access
door for inspection and maintenance
purposes.
10. Terminations. Where the Pipe
Sections pass through the roof, a hole
must be cut to provide a minimum
