Floor Drain
This drain (customer supplied) receives the excess water from the steam generating system.
Rack Carrier
When the loading door is closed, the rack carrier lifts and rotates the oven rack.
Rack Stop
The two rack stops are located on the carrier and secure the oven rack in place during baking. The leading
edge of the forward stop must manually flipped down to unload the oven rack. The stop will
automatically return to the up (loading) position when the rack is removed.
Hood
Steam and burner exhaust is discharged into the hood. Grease is channeled to and collected in a grease
cup for later removal.
Hood Exhaust
Exhaust passes through a duct to the hood exhaust outlet. A customer-supplied exhaust blower is
recommended that the hood be wired to the external device terminals in the service box. This insures the
hood is on whenever the oven is on. The "POWER" switch on the oven control panel activates the blower.
The blower must be running before the oven will operate. A factory installed airflow switch disables heat
until airflow exists.
Interior Door Release
This door release allows the door to be opened from inside the oven.
