ELECTRICAL CONNECTION — Cord Connected Ovens
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL
ELECTRICAL CODES.
WARNING: THE SUPPLY CORD ON THIS OVEN IS PROVIDED WITH A GROUNDING PLUG.
THE OUTLET TO WHICH THIS PLUG IS CONNECTED MUST BE PROPERLY GROUNDED. IF
THE RECEPTACLE IS NOT THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN.
The wiring diagram is located on the inside surface of the right side panel as you face the oven.
START-UP PROCEDURE
The Gas Combi Ovens are equipped with a gas burner for convection heating and a gas steam
generator for atmospheric steaming; two independent flues exhaust the burnt gases. Become familiar
with the entire manual before continuing with this Start-Up Procedure. Remove the tray rack, grease
filter and fan baffle from the oven cavity. Turn gas and water on.
Press the ON button.
• Select Combi Mode and adjust the steam time to 50% by pressing
four times (four
indicator lights are lit).
• Leave oven temp setting at 302°F and the timer display blank, [-]h [--]min.
• Close the oven door and press the Start Button. The oven convection fan rotates counterclockwise.
The oven flue vent should be open.
• After a delay of 50 seconds while the oven adjusts for Combi Mode, the sparker on the left side of
the burner should ignite the Convection Burner. Observe blue flame. On some units, the Convection
Burner ignites for an instant, goes off and then comes back on (while the flame sensor is tested).
On other units without the double ignition sequence, the Convection Burner may ignite and stay on.
After an additional 70 seconds, the steam generator flame should ignite. Observe blue flame
through window below controls.
If the Convection Burner does not ignite, the NO Convection Burner indicator light,
, will be lit.
• Wait 30 seconds until the
light starts to flash and the buzzer sounds.
• Reset the Convection Burner by pressing the Reset Button above the
indicator light.
• This procedure may need to be repeated several times until all of the air in the pipeline is replaced
by gas. The longer the pipe, the longer it will take to remove the air from the pipe.
If the Steam Generator Burner does not ignite, the NO Steam Burner indicator light,
, will be lit.
• Wait 10 seconds until the
light starts to flash and the buzzer sounds.
• Reset the Steam Generator Burner by pressing the Reset Button above the
indicator light.
• This procedure may need to be repeated several times until all of the air in the pipeline is replaced
by gas.
If a make-up air system is part of the vent hood, make sure there is no down-draft pushing hot
combustion gases from the flues back into the oven.
Press OFF and observe that the pump drains the steam generator for about one minute. The door will
open. After the oven is cool, reinstall fan baffle, grease filter and tray rack.
CONFIGURE CONTROLS
Depending on which control is furnished, perform CONFIGURATION MODE — PROGRAMMABLE

BEFORE FIRST USE
Before using the oven for the first time, it must be "burned in" to release any odors that might result from
heating the new surfaces in the oven. Operate the oven at 480°F for 45 minutes in Convection H
