Maintenance Tips
-
Daily burn-off cleaning: After service, run burners on high to carbonize grease, then brush grates while warm for easier removal of residue.
-
Clean cast iron grates: Scrape food debris after each use and re-oil lightly to prevent rust and maintain strong searing performance.
-
Empty grease system daily: Clean full-width grease gutter and removable drip pan to prevent flare-ups, smoke, and blockages.
-
Check burners & radiants: Inspect and clean burners and cast iron radiants to ensure even heat distribution and prevent clogging.
-
Clear grease channels: Keep cast-in grease troughs and drainage paths free of buildup for safe and consistent operation.
-
Inspect gas connections: Regularly check for leaks, loose fittings, or wear to maintain safe gas flow and operation.
-
Ventilation upkeep: Clean hood and exhaust systems frequently due to high grease output during charbroiling.
-
Deep weekly cleaning: Remove grates, radiants, and burners for thorough degreasing and carbon removal.
-
Control knob care: Keep valves and knobs clean for smooth adjustment and reliable flame control.
-
Proper shutdown: Turn off gas supply and allow full cooling before cleaning or covering the unit.
