This is a natural, non-electric extractor. Airflow efficiency depends on the layout of your BBQ area and the type of charcoal or wood used.
Before first use, remove all protective films and residues.
To clean the exterior, wait until all surfaces are cool. Use a microfiber cloth and soapy solution. Avoid harsh cleaners, chlorine, or abrasives on stainless steel.
Some discoloration from high heat is normal and not covered by warranty.
Routine cleaning before and after each use is recommended.
