using a Gas Vent Support installed under
the flashing. As an alternative to using
the Gas Vent Support, you can use a
Wall Strap if there is a roof joist nearby,
or you can field-fabricate a support-
plate that will both support the weight
and prevent lateral movement of the
vent. Do not penetrate the inner liner of
the vent. It is important that the rigid
sections of Gas Vent are properly secured
for a safe installation.
Figure 7
-When installing DuraConnect II as a
segment in a Crawl Space, rigid Type B
Gas Vent must extend a
minimum of 3” through any penetration
(wall, floor, ceiling, etc). The rigid Type B
Gas Vent must also be supported using
a Firestop Support, Gas Vent Support or
Wall Strap, in order to remove the weight
load from the DuraConnect II section.
Please refer to the full instructions for
DuraConnect II in the front part of this
document, and Type B Gas Vent (L204)
for the remainder of the installation.
