Q&A

Maintenance Tips

• Daily grease removal: Wipe all stainless steel surfaces, shelves, and backsplash areas to prevent heavy grease buildup from high-volume cooking vapors.
• Keep flue path open: Ensure the vertical flue channel stays clear so exhaust fumes move efficiently into the hood system without restriction.
• Deep clean regularly: Perform thorough degreasing of both high shelves to remove airborne grease and maintain sanitary conditions in busy kitchens.
• Inspect mounting stability: Check wall brackets and range connections for looseness caused by heat cycles and vibration during daily operation.
• Prevent grease fire risk: Maintain a clean zone behind cooking equipment since flue risers sit directly in the path of hot grease-laden air.
• Use non-abrasive cleaners only: Clean with mild detergent and soft cloths, wiping along the grain to preserve stainless steel finish and durability.
• Check shelf loading: Avoid overloading either shelf to maintain structural integrity across the full 120” heavy-duty frame.
• Ensure proper hood alignment: Keep the riser aligned with the ventilation system so airflow capture remains efficient and consistent.
