Maintenance Features

The manual provides detailed instructions for component removal and installation, facilitating maintenance and repair. Key maintenance features include:

Component Removal and Installation:

Wok Grate and Top Plate: These components are removable for cleaning or replacement. A warning is issued regarding the heavy weight of the wok grate, recommending two people for removal to prevent injury or damage.
Wok Frame Assembly: Instructions are provided for removing the wok frame, which involves detaching mounting screws and lifting the assembly from the burner box.
Wok Spacer Rail: The spacer rail can be removed by lifting it directly upward from its supports.
Solenoid: The solenoid, which controls gas flow, can be removed by disconnecting wire connectors and gas lines.
Wok Burner Assembly: The entire wok burner assembly, including the surface burner, gas burner, and ignitor, can be lifted directly from the tray for service.
Wok Ignitor and Electrode: Detailed steps are provided for removing and installing the ignitor and its electrode, including disconnecting wires and loosening retaining nuts.
Wok Tray: The wok tray can be removed after detaching the wok gas elbow and mounting screws.
Wok Mounting Bracket: The bracket is removed by detaching its mounting screws.
Bottom Panel: The bottom panel can be removed to access internal components, requiring the movement of the wok orifice assembly and elbow.
Manifold: Instructions for removing the manifold are provided, emphasizing that gas lines and switch wiring do not need to be removed for manifold replacement.
Orifice Holder: The orifice holder, including its mounting bracket, can be removed by detaching screws and gas lines.
DSI Board Cover and DSI Board: The DSI board cover and the DSI board itself can be removed by detaching mounting screws and wire connectors.
Spark Module: The spark module, responsible for ignition, can be removed by disconnecting electrode and power wires and detaching mounting screws.
Wiring Cover: The wiring cover can be removed to access internal wiring.
Power Cord: Instructions for removing and installing the power cord, including strain relief and wire retainer, are provided.
Regulator: The gas regulator can be removed by detaching gas lines and mounting screws. A warning is included to use only pipe thread compound for gas connections, not Teflon tape.
Burner Grates, Caps, Assemblies, and Pans: These components are easily removable for cleaning and maintenance.
Island Trim: The island trim can be removed by detaching screws and lifting it from the unit.

Uneven wok heating
Wok being too hot
Popping noise during simmer mode
Flame appearance issues (tall, yellow, pulsing flames)
No knob or lighted knob display
No power to the unit

DSI Board Troubleshooting Flowchart: A detailed flowchart guides technicians through testing the DSI board for supply voltage, griddle thermostat (if present), DC voltage for solenoid output, continuity of J2/GND wire, and continuity of griddle/FT electrode.

Gas Pressure Testing: Instructions are provided for testing gas supply pressure, which is critical for diagnosing performance issues. This includes specifications for natural gas and liquid propane, methods for connecting a manometer to the unit manifold, and common reasons for pressure issues (e.g., undersized flex lines, shut-off valves, or supply lines).
