The chamber cannot readily dissipate heat generated by friction without a fully open fresh air
damper. With the fresh air damper fully open, the thermal equilibrium temperature is the mini-
mum operating temperature of the chamber.

When the damper is in full open position, the oven may not be
able to heat to the maximum oven operating temperature.
3.2.1.3. Exhaust Damper Control
Adjusting the exhaust damper ( Figure 6 ) aids in pressurizing the chamber.
3.3. Optional Adjustable Louvers

This section applies only to ovens that include the optional
adjustable louvers. Ovens without the louver option do not have
adjustable airflow.
RAD oven series come standard with perforated supply and exhaust panels (Figure 7).
Optional adjustable louvers provide an extra measure of airflow customization. Figure 8
shows the initial factory settings for the optional louvers.
