Char-Broil Commercial Quantum 3-Burner Gas Grill Model #463247109

Char-Broil Commercial Quantum 3-Burner Gas Grill Model #463247109

Char-Broil LLC.

The Bottom Line

The Char-Broil Quantum represents an innovative approach to an inexpensive all infrared gas grill. This unit uses a simple sheet of perforated stainless steel to convert the output of a standard gas burner into infrared energy. This unit has three burners that put out only 30,000 BTUs under 500 square inches of cooking space but can still reach temperatures around 700 degrees F. You also get the standard Char-Broil side burner. Unfortunately this grill is constructed from low quality and thin stainless steel limiting its durability. Each burner has an individual temperature gauge.


  • High, even heating
  • Individual burner temperature gauges


  • Low quality 430 stainless steel and painted steel construction
  • Low quality stainless steel burners
  • "Infrared" cooking system can be problematic and require high maintenance


  • Three 10,000 BTU 400 series stainless steel tubular burners under "infrared" diffusers
  • 500 square inches of primary cooking area for a total of 680 square inches of grilling space
  • 30,000 BTU maximum output from the main burners
  • 13,000 BTU standard side burner under a flush mounted cover
  • Unique complete "infrared" design for high temperature cooking
  • 430 stainless steel and painted steel construction
  • Electric (AA-battery) ignition
  • Individual temperature gauges for each burner mounted above burner knobs
  • Compatible with Char-Broil's "Dual Fuel" system (you buy the conversion kit ($50USD))
  • Manufactured in China by Char-Broil exclusively for Lowes Home Improvement Stores

Guide Review - Char-Broil Quantum 463247109 - Discontinued

This model has been discontinued. It is replaced by the Char-Broil Quantum 3-Burner Model #463257110.

Infrared remains a priority for Char-Broil and this Quantum Infrared Grill, exclusive to Lowes Home Improvement stores, is a smaller version of last year's model. This 3-burner version comes in at a lower price (around $400) and loses some of its stainless steel in favor of cheaper, painted steel. Probably the most unique feature is the individual temperature gauges on each burner. Since heat builds up under the infrared plate this grill can tell you the cooking temperature at the grate level. This isn't an effective way of telling your grill temperature for indirect grilling, but it will tell you how hot your steaks are cooking at.

This three burner gas grill puts out a maximum of 30,000 BTUs under 500 square inches of primary grilling space. This seems low, but because of the efficiency of infrared this grill can still hit temperatures around 700 degrees F. In good working condition this grill can put out a high, even heat that is great for searing. Additionally you get a 13,000 BTU side burner. This is the standard Char-Broil side unit, and while flimsy it is functional. There is no rotisserie burner on this unit, but that really isn't necessary.

There are two primary problems with this grill. First, this model, like all Commercial Series Char-Broil grills is made from low grade (400 series) stainless steel. This limits the durability of the grill and will cause it to discolor and rust early. You can't count on this grill lasting.

The other problem with this grill is the "infrared" system. Basically what makes this grill and infrared grill is a thin sheet or perforated stainless steel (also 400 series). This sheet needs regular "gentle" cleaning according to Char-Broil to keep the holes in it clear. If this sheet gets too dirty the grill will not work properly. You need to be very careful in maintaining this grill to keep it working.

Firebox rusted out., Member grillingmick

Although I have to say this is the best grill I have ever used for grilling fish, steaks and pork (no flare up problems), for the price $399, I expected it to last more than 4 years. I always kept it covered and yet I still had a rust out problem on both sides of the firebox. Also, noticed that the stainless steel tends to rust (not of the highest quality). The problem is along the inside ledge that holds the grates, the rail and both sides rusted out.
