RECOMMENDED EXHAUST FLOW RATES
In accordance with mechanical codes, make up air must be supplied. For commercial
kitchen make up air, the amount is determined by the exhaust hood flow rate requirements & all
other exhaust flow rate requirements in the kitchen.
At a minimum, smoke candles must be used for a Capture & Containment (C&C) test. Re-
fer to the Ventilation Requirements disclosed in the Oven section in this manual.
A Test & Balance (TAB) report is recommended after installation has been completed.
Below are the minimum items to be included is this report:
Total airflow on all A/C, Make-Up Air (MUA), & exhaust systems.
Airflow on each supply & exhaust grille.
Airflows on exhaust hoods compared to design specifications.
A final air balance report, with any corrections of issues found in the report, will help to
insure that your building systems are functioning properly & efficiently.
Refer to “Oven Ventilation Requirements & Guidelines”
NOTE
All values are CFM [M3/Min] unless otherwise noted. Figures represent TOTAL
VOLUME measured at the duct.
