Floor Drain
This drain (customer supplied) receives the excess water from the steam generating system.
Rack Carrier
The Rack Carrier attaches to the top of the oven rack.
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 be 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, if present, is channeled to and collected in
a grease cup for later removal.
Hood Exhaust
Cooking fumes and burner exhaust pass through a duct to the hood exhaust outlet. A customer-supplied
exhaust blower is required. The hood can 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.

Pre-Installation
Check the area where the oven is to be installed for the following:
• No electrical conduit or wires are to be under the floor of the oven.
• The oven must be mounted on a non-combustible surface. This includes the structure beneath the
floor. The floor must me level within 3/4”. See Fig. 1 Page 4, and above CAUTION!
• Ceiling height above the oven should be sufficient to allow servicing the lifter, vent, and blower
motor assemblies. The maximum height needed for tilting the oven up is 105 inches.
• Clear access is needed to the roof or exterior of the facility for hood exhaust. Check local codes for
correct venting.
• Caution should be taken when enclosing hood to ceiling and oven is under a fire sprinkler; hood
exhaust stack will emit heat.
• Access is needed for an air-gap drain in the rear left corner of the oven.
• Adequate space is needed in front of the oven to load and unload racks. Racks are hot and need
space to cool.
• The oven needs make-up air to operate. The hood exhaust will need at least 600 CFM for Model
BARO-1G and 800 CFM for model BARO-2G.
• Local and national codes will require an electrical shut-off within a reasonable distance to the oven.
• Local and National codes will require access to a manual Gas Shut-off.
• The door swing (46.0”) will need to be clear to allow adequate loading and unloading of the oven.
