The specified Vulcan VFS foundation/soffit and VE eave vent models have OSFM listing 8165-2192:0502 for wildfire-area use.
The location labels matter because the size choices repeat. Foundation/soffit models VFS414, VFS614 and VFS814 measure 3.5 by 14, 5.5 by 14 and 7.5 by 14 inches, respectively. VFS422, VFS622 and VFS822 measure 3.5 by 22, 5.5 by 22 and 7.5 by 22 inches. The corresponding eave models are VE3514, VE5514 and VE7514 for the former size group, and VE3522, VE5522 and VE7522 for the latter. Match the model and its listed application, rather than ordering by the opening dimensions alone.
The OSFM handbook names ASTM E2886 as the test protocol for this listing. Its product description includes an aluminum matrix with an intumescent coating and stainless steel ember mesh. Those are features of the named finished vents; the listing should not be read as a recipe for assembling a substitute from similar materials.
For a replacement vent, start with the foundation, soffit or eave location, then identify the listed model and size. The handbook directs readers to the manufacturer's installation instructions and product data sheets. Check those documents and the live BML listing before specifying the vent so that the finished product and its installation match the cited listing.
