to ON. You will hear the sound of the recirculating fan starting.

c. Shut oven door.
d. Check that the control display turns ON.

2. Operate the temperature control as desired.

Notice

The heater of the Class A oven cannot be energized until the
forced exhaust system has brought in a minimum amount of
fresh air into the chamber. The purge timer provided prevents
the heater from energizing until the oven has had enough time
to bring in the required amount of fresh air. The airflow switch,
which closes when the exhaust system is running, energizes
the purge timer. The predetermined purge time for the RFD1-42-
2E is two minutes.
