Maintenance & Usage Tips

The Rotisserie Advantage: To get the best results from the 15,000 BTU rear rotisserie burner, always ensure your meat is balanced on the spit rod. A well-balanced roast prevents the motor from straining and ensures uniform cooking. Always use a drip pan on the grates beneath the meat to catch drippings for gravy.

Maintaining Stainless Steel: To keep the stainless steel finish looking new, clean it with a dedicated stainless steel cleaner periodically. Never use steel wool or abrasive pads, as these can permanently scratch the surface and destroy the protective layer, making it prone to rust.

Grill Seasoning: Before your first cook, ensure you “burn off” any manufacturing residue by running the grill on high for 10–15 minutes. Afterward, wipe the grates with a high-heat oil (like grapeseed or canola) to season them—this helps prevent food from sticking and adds a layer of protection to the stainless steel.

Fuel Safety: The S 590 Pro uses a sliding propane tank tray, which makes changing out your 20lb tank very easy. Always check the fuel hose for cracks or brittleness at the start of every grilling season to ensure a safe, leak-free connection.
