Central vacuum: exhaust, depressurization and fire separations
Treat a central vacuum as an exhaust/piping system that can affect pressure, IAQ and fire separations.
VERT / GREEN
Document motor, bin, exhaust and piping route.
JAUNE / YELLOW
A central vacuum can exhaust significant air; Health Canada recommends outdoor exhaust or HEPA filtration for IAQ.
ROUGE / RED
Piping crossing suite separations, a system shared between suites or combustion backdrafting: review fire and pressure design.
Quick triage
What the professional checks
The professional checks exhaust flow, makeup air, combustion, discharge, motor/bin, penetrations and suite separations.

Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
V17
Specialized systems to cross-check
V17 completes gas, soil, water, fire, climate and structural interfaces.
