Char-Broil Commercial Quantum 4-Burner Gas Grill Model #463247209

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 four burners that put out only 40,000 BTUs under 580 square inches of cooking space but can still reach temperatures around 700 degrees F. You also get the standard Char-Broil side burner "oven" with griddle. 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

  • 13,000 BTU side burner "oven" with griddle
  • Unique complete "infrared" design for high temperature cooking
  • 430 stainless steel construction throughout the grill including grates and burners
  • 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 Commercial Quantum Infrared 4-Burner 463247209 - Discontinued

This model has been discontinued. It is replaced by the Char-Broil Quantum 4-Burner Model #463247310.

Infrared remains a priority for Char-Broil and this Quantum Infrared Grill, exclusive to Lowes Home Improvement stores, is an update of last years model. There are a few changes with this model though the price remains the same (around $500). 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 four burner gas grill puts out a maximum of 40,000 BTUs under 580 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 oven with griddle for a wide range of cooking tasks. 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 and grill will not work properly. You need to be very careful in maintaining this grill to keep it working.

Run away from these grills..., Member Unhappy_Griller

Made the mistake of buying (into) one of these. CharBroil markets them under several different names: Tru-Infrared (previously 'Quantum') - 'Commercial Series', 'Gourmet' , etc.. For the first year or so it worked fine. The cooking experience, while OK, doesn't live up to the IR hype. It has good heat and it (was) fairly even. Other than that, it's just a high powered grill. The claims of 'incredible' cooking can be replicated on any adequately powered conventional grill by a competent chef. Then there's the maintenance. You WILL spend MUCH more time cleaning it if you follow CharBroil's recommendations. Oil, pre-heat, cook, burn off, cool-down, disassemble, scrub, oil, reassemble.... And, all of this high heat cooking/burning requires much more gas. It uses at least twice what a normal grill does. Keep a spare tank handy. Now the kicker... The reason CharBroil has you do the whole oiling/scrubbing/oiling routine is to prolong the life of the so-called 'stainless' grates/troughs. Without this maintenance, these parts would rust away & fall apart in the first few weeks/months. With the maintenance, the parts will last about a year...or 'til just after the warranty runs out. And, then you get to spend $100 for replacement parts....every year...or at least until the rest of the grill rusts away. Run.
