Daniel, engineering manager at Masterbuilt, explains the charcoal hopper on the Masterbuilt Gravity Series Grill + Smoker.
From the Masterbuilt Product team on the hopper metal plates and firebricks:
Metal Plates
The metal plates in the lower portion of the hopper hold the firebrick in place and protect it during shipping. These burn out and drop into the ash pan. They are not necessary for the grill to function and we’re not offering a replacement part, since they are meant to be temporary.
Firebrick
In the Gravity Series Hopper, your fire is contained to a 6” - 12” area that is reinforced with a food-safe soft ceramic firebrick to handle the higher temps in the lower portion of the hopper. The ingredients in the food-safe ceramic are FDA allowed for use in food or as an indirect additive used in food contact.
The firebrick takes the heat from the charcoal fire and is to be replaced only once a hole burns in it that is more than 0.5” deep and 5” in diameter. These firebricks will be a warrantied part and will also available for purchase post-warranty at a retail of $29.99 for the full set (4 firebricks with temporary metal plates). In our testing, we’ve seen firebricks last multiple years. You do get some initial firebrick degradation during burn-in and initial usage, but then degradation tends to stabilize.
