Status derived from the cited listings by a published rule, never hand-assigned. Each chip
above is one evidence channel and its direction. A listing is not a permit — the authority
having jurisdiction decides.
FireStorm documents V2 Vents as complete assemblies combining stainless-steel ember mesh with a heat-activated intumescent honeycomb matrix and ASTM E2886 testing. CAL FIRE OSFM listing 8165-2426:0001 covers six series for gable, continuous soffit, foundation, eave, sub-base, and round-eave applications, with the exact model and size schedules in the live listing.
Kind: listed-assembly.

The manufacturer catalog includes configurations beyond the live BML schedule. Match the series, model, size, flange, mesh orientation, matrix, fire caulk, NFVA, and installation orientation to OSFM listing 8165-2426:0001; activated intumescent components require replacement. OSFM listing is not a permit. The authority having jurisdiction decides. Can I use this here
This trace joins product evidence to a sourced code application, then keeps every boundary,
map, date, project check, documented constraint match, and still-undocumented field visible.

Where this applies
A product is a national record; where it applies is a fact about a place. The rule that
binds a given address — and every product matching it — is published on that place's own
answer page, linked above and re-linked by the location lens. The complete per-place
claim graph for this record, including every open official check, is in its
JSON twin .
