Step 3: Now, access the calibrate exhaust sensor menu and measure inflow velocity using the
recommended procedure found in Table 7.0.
If necessary, adjust the exhaust system to achieve the correct inflow velocity. Use Table 7.1 to
relate downflow and exhaust/inflow volumes and corresponding average airflow velocities. It is
always desirable to achieve airflow values that are set as close as possible to nominal. This is
especially applicable to the inflow velocity and its relation to exhaust volume, since the exhaust
sensor only monitors the exhaust airflow. If the inflow velocity is calibrated at the outer edge of
