NFPA 86 — Direct-Fired Safety Ventilation

Pre-ignition purge volume (4× chamber)—ft³

Purge time @ recirc fan CFM—

Combustion ventilation (products of combustion)—SCFM

Formula used: combustion ventilation = (burner BTU/hr ÷ 1,000,000) × 183 SCFM. This is separate from recirc CFM and sized off the burner output above — true it up once your supplier confirms the actual burner unit.

Zone Velocity Profile (advisory)

Front runs low to protect uncured powder from blow-off. Back runs high to finish cure. Adjust % per zone on your VSD/damper controls — this is a starting profile, not a fixed rule.
