LEX 605 with Side Burner and Infrared Bottom and Rear Burners Propane Gas Grill

Product Overview

The LEX605RSBI provides 7 different ways of cooking. Go from high heat searing over the integrated ceramic infrared grill to baking and roasting. The infrared burner heats within seconds to lock in juices. The double walled lid and rear grill hood contain the heat giving you oven like performance. The heat produced on a Napoleon Grill is so even you can even bake on the grill. There are 605 sq. in. of grilling surface on the LEX605RSBI Gas Grill. That means you can fit up to 32 four inch burgers on there at once, and that's not including the warming rack area. The stainless steel WAVE cooking grids transfer heat beautifully into whatever you're cooking, creating those unique Napoleon sear lines. Have the freedom to prep your meal on the grill with the large side shelves and included cutting board. Then, while the food is cooking on the grill, prepare sauces or saute on the gas range burner. The iGlow knobs are backlit by stunning blue LED lights that will burn for over 30,000 hours. There is a full width, tapered drip pan to catch anything that the stainless steel sear plates don't turn into delicious flavor. Under that there is the permanent grease tray. The LEX Series Gas Grills light easily with the unique JETFIRE ignition system. That jet lights the burners directly through the control knobs and will last for years because it stays out of the heat zone of the burners. Everything about this grill screams high-end, except for the price tag.

    Napoleon Lex 605 Review
    Purchased May 2020. Plenty of room to grill and infrared burners provide excellent heat and can be used to cook quickly. Sturdy and well built. Downside: side burner igniter does not work. Side burner area does not allow for a large pan as rotisserie bracket sticks our and prohibits a pan to be squarely on burner. Does not come with a tank gauge to tell how much gas remains in tank. Catch basin for burnt food particles is too small. Flame covers do not distribute heat evenly.

      Way better than expected
      I bought this particular grill because of the reviews and wanted a regular side burner. I watched the assembly video on YouTube and assembly was as expected. I will say I was a little disappointed to see that this Unit was made in China while all the advertising show being made in North America. With that said the unit is great - Only issue was the igniter on the side burner did not want to light - bent the electrode and worked fine. Sorry to say, our weather is still been haven't had a chance to use it yet. Happy I got it, envy of the neighbors

          An absolute game changer
          You don’t realize how much of a difference a proper BBQ makes until you have one. The chicken is so tender, steaks basically cook themselves, everything is 10x easier to get chef quality food. Assembly was a bit of a pain and some of the fasteners were pretty cheap feeling, plus there’s a couple weird support rods that don’t seem to do much but be a pain. These are small prices to pay for such an incredible grill.

          Good Bbq.
          Nice Bbq and good quality. Issue with mounting screws when connecting the top of bbq to main bot cabinet. One of the mounting screws was touching the side burner gas line, I had to cap the screw with a plastic sleeve. Ignition system doesn't work that well for a brand new bbq. Ignition system doesn't work at all for the side burner. The sizzle zone works great and easy temperature control.

          Best BBQ ever
          I purchased this BBQ 3 months ago and it's the best. Retains heat better than any BBQ I have ever had. The stainless steel grills are very easy to clean. I will never buy another BBQ that's not a Napoleon.

            Best BBQ ever
            We purchased this beautiful BBQ mainly because of of the sizzler side. We just love it. Our filet mignon are done just the way e like them. The cleaning of the grills are easy to do.
