🛡️ Indoor Air Quality (OSHA / ANSI Z83.4 Limits: CO <5.0 PPM, NO2 <0.5 PPM in Supply)

Direct Fired MUA Combustion Air Quality Calculator

Evaluate indoor air quality and combustion byproduct safety for direct gas-fired make-up air ventilation under ANSI Z83.4 & OSHA standards: verify supply air Carbon Monoxide (CO < 5.0 PPM) and Nitrogen Dioxide (NO2 < 0.5 PPM) concentrations across the full burner modulating range, size electronic airflow interlocks, and IAQ testing yields.
