OPERATION
NOTICE
No attempt should be made to operate oven during a power failure.
A manual gas shutoff valve is located behind front lower panel for turning gas on and off.
OPERATION (FOR STANDARD CONTROL OPTION)
Lighting the Combi – The Combi has an intermittent standing pilot. When the unit is turned on, the lighting
sequence is controlled by an ignition module. A hot surface ignitor ignites the pilot, which stays lit for the
entire time the Combi is turned on and the flame is proven by the flame sensor.
Re-Lighting the Combi – If the Combi does not light on the first attempt, do the following:
1. Shut off all gas.
2. Wait five minutes.
3. Repeat lighting instructions above.
Turning the Combi On and Off – The power switch at the top left corner of the control panel turns the unit
on and off. When the power switch is turned on, the Combi begins a diagnostic check and initiates the pilot
lighting sequence. If the diagnostic check or the lighting sequence fails, a code word will appear in the time
display and operation will be suspended. Otherwise the unit will begin operation in the startup default mode,
which is oven mode at 350ºF.
Choosing Fan Speed – The Combi has a two speed fan which can be controlled with the fan speed selector
switch at the upper right hand corner of the control panel.
Choosing the Cooking Mode
Oven Mode is selected by pressing the OVEN button, which causes the light above the OVEN button to
illuminate. In oven mode, the Combi acts exactly like a convection oven. If when the OVEN mode
button was pressed the unit is not at the setpoint temperature, the temperature display will flash until the
setpoint temperature is reached.
Steam Mode is selected by pressing the STEAM button, which causes the light above the STEAM button to
illuminate. In steam mode, the Combi acts exactly like a pressureless countertop convection steamer. If
when the STEAM mode button was pressed the unit is not at the setpoint temperature, the temperature
display will flash until the setpoint temperature is reached. In steam mode, the setpoint temperature is
preset to 215ºF, to allow pure, slightly superheated steam to circulate within the cavity.
Combi Mode is selected by pressing the COMBI button, which causes the light above the COMBI button to
illuminate. In combi mode, a high moisture cooking environment is created through carefully controlled
humidification. If when the COMBI mode button was pressed the unit is not at the setpoint temperature,
the temperature display will flash until the setpoint temperature is reached.
Steam Inject Mode is the only mode that can used in conjunction with another cooking mode, namely oven
mode. Pressing the STEAM INJECT button causes steam to be delivered to the cavity for as long as the
button is held. The intent is to provide the desired surface characteristics (crispy, shiny crust) on bread
products, and for any other products that would benefit from timely steam injections.
Vent/Cool Mode is designed to quickly cool the cavity from a high setpoint temperature to a low temperature
using a combination of high fan speed and a cooling spray of water
