The Char-Broil M500 style 4 burner grill is similar to its N480 cousin but with a series of extra features that make it yet another great value in its own right. The grill has a great appliance style cart design with 2 doors, and a combination of stainless steel and porcelain coated steel construction. The 4 burners fire out 50,000 BTU's of heat to cover the 500 sq. in. of primary cooking area and the 280 sq. in. of secondary cooking space. The 13,000 BTU side burner of course provides a great deal of versatility while grilling. The M500 features a new Char-Broil exclusive "Surefire" Electronic ignition as well as the Char-Broil patented "Dual Fuel" design which allows for the grill to be easily converted from LP to Natural Gas with the purchase of a conversion kit (can be converted in lass than 30 minutes). As with all grills, we recommend keeping the firebox clean to help avoid flare up as well as using a grill cover to protect your invest.
