Features & Specs - Napoleon Prestige Pro450RB
Stainless-steel grates Primary cooking grates made of stainless-steel are generally sturdier than those made of coated steel and resist rust even without a porcelain coating.
Coated-cast-iron grates The grill's primary cooking grates may be made of porcelain coated cast-iron, which generally sears meats better and keeps grilling temperatures more consistent than grates made of porcelain coated steel. The porcelain coating usually makes such grates easier to clean than other surfaces, and the grates should resist rust as long as their porcelain coating isn't chipped.
All or mostly stainless Includes more than just a panel or other trim. Based on our limited tests, nonmagnetic stainless is less likely to corrode.

Long-warranty burners While burners remain the grill's most-replaced part, most are warranted for only 3 to 5 years. Better burners are covered for 10 years or more.
Side burner A side burner, which resembles a gas-stove burner and has its own heat control, is handy if you want to cook vegetables or sauce without leaving the grill. A side burner could also be an infrared burner used for searing.
Infrared burner Gas burner that uses infrared technology (ceramic burner, plates and screens, or troughs as some examples) for cooking. An indirect flame is used for cooking food. Burner can be located as the main burner, side burner, rotisserie burner, or any combination of burners.
Have used this product on natural gas for more than 7 years and haven't had to replace anything. Even the igniter battery is original. <br /> <br />The stainless side burner, heavy main burners and rotisserie functions work superbly. The heavy cast lid is hinged at a point where it is perfectly counterbalanced and can be opened and closed with little effort. Grill is effective at 0'(F)or below in fairly calm conditions due to the tight construction. This a quality item which with reasonable care should last 15 years or more.<br /><br />Cons.<br />It does need a yearly cleanup under the grill with a shop vac. Burner jets tend to clog and must be cleared annually with a wire brush and sharpened probe. Disposable foil grease trap does not always catch all the grease from the grill. Storage area door handle is awkward to grip.
