Maintenance Tips

• Clean stainless steel surfaces daily: Use mild, non-abrasive cleaners to remove grease and maintain corrosion resistance (heavy-duty stainless steel construction).
• Keep flue outlet clear: Ensure the 2-3/8” flue opening is free from grease or debris to maintain proper exhaust flow and safe ventilation.
• Prevent grease accumulation behind unit: Inspect weekly—large 120” backguards are prone to hidden grease buildup, increasing fire risk in commercial kitchens.
• Maintain proper ventilation clearance: Ensure adequate airflow around the 17” high backguard to avoid heat buildup and ensure efficient exhaust removal.
• Check mounting and stability: With a ~140 lb structure, regularly tighten fasteners and ensure secure attachment to the range.
• Avoid harsh chemicals: Protect NSF-certified stainless steel by using non-corrosive cleaning agents only.
• Schedule professional inspections: Include flue riser and ventilation checks in routine commercial kitchen maintenance for compliance and performance.
