Maintenance Tips
-
Daily grate cleaning: Remove cast iron grates and brush off carbon buildup after each shift to maintain strong sear marks and prevent flare-ups.
-
Clean radiants regularly: Remove and clear reinforced cast iron radiants so burners stay unclogged and heat remains even across the 36” surface.
-
Empty grease system daily: Clean the full-width grease gutter and removable drip pan to reduce fire risk and improve sanitation.
-
Check burner ports weekly: Inspect the (6) 15,000 BTU burners for grease or debris blockage to maintain consistent flame and 90,000 BTU output.
-
Maintain ignition system: Ensure standing pilot lights reliably and flames burn steady blue for efficient gas operation.
-
Wipe stainless steel surfaces daily: Clean front, sides, and landing ledge with mild detergent to prevent corrosion and maintain food-safe surfaces.
-
Avoid abrasive tools: Use soft brushes/cloths only to protect cast iron seasoning and stainless steel finish.
-
Level the unit: Keep adjustable 4” legs properly set for even heat distribution across the slanted cooking surface.
-
Ensure ventilation clearance: Keep rear and sides free of obstruction so heat and grease vapors flow properly into the hood system.
