Q&A

Maintenance Tips

• Clean stainless steel daily: Wipe all surfaces with mild detergent and warm water to remove grease and food residue, preserving NSF-grade corrosion resistance and hygiene.
• Keep flue outlet clear: Regularly inspect the 2-3/8” flue opening to ensure unobstructed exhaust flow and safe ventilation performance in commercial kitchens.
• Sanitize double shelves: DHS-54 includes two heavy-duty shelves—clean them after each shift to prevent grease buildup and cross-contamination.
• Check mounting stability: Inspect and tighten brackets and fasteners periodically to maintain secure installation behind heavy-duty ranges.
• Prevent grease accumulation: Clean behind and around the riser weekly to reduce fire risk and maintain safe kitchen conditions.
• Maintain ventilation clearance: Ensure the area around the 35” high backguard remains unobstructed for proper heat and exhaust flow.
• Use non-abrasive cleaners only: Avoid harsh chemicals or steel wool that can damage stainless steel finish and reduce equipment lifespan.
• Routine inspection: Check for loose fittings, shelf stress, or buildup during scheduled commercial kitchen maintenance for long-term reliability.
