Char-Broil Quantum 4-Burner Model #463247311

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.

This model has been discontinued. It is replaced by the Char-Broil TRU-Infrared 4-Burner Model #463247512.

Infrared remains a priority for Char-Broil and this Quantum Infrared Gas Grill, exclusive to Lowes Home Improvement stores, is the replacement of last year's model. Nothing has been changed with this model except the model number. The price remains 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 the lid is 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.
