Firebox and Burn Grate Assembly Maintenance
It is recommended that the rebox assembly is regularly inspected to be certain that it
remains free of ash and debris which will ensure proper performance.
The rebox is a fully welded structure that carries the burn grate and channels the
combustion air. The rebox is bolted to the cooking chamber oor. The seams on the
hopper wall and the oor of the cooking chamber are sealed with a high temperature
silicone. Perform regular inspection of the silicone seal, particularly on the top side of
the rebox along the hopper wall. If this seal is broken, remove the old silicone, clean
the surface, reapply new high temperature silicone and let it cure. We recommend us-
ing Permatex 81878 high temperature silicone.
The seating of the burn grate into the rebox is critical for proper grill performance.
Begin by resting the right hand side of the burn grate on the re pot and then pressing
down on the left hand side of the burn grate until fully seated. Once the burn grate is
seated there is little to no movement in this assembly. Also, check to be certain that the
igniter assembly is centered in the respective hole in the burn grate.
Stainless Steel Burn Grate
It is important to regularly check the combustion air holes located on the oor and
sides of the burn grate for any blockage or build-ups. Using a wire brush or at-head
screwdriver, scrape o any build-up or debris.
Burn Grate Inspection
NOTE: Only do this when the smoker is completely cool.
To ensure that the pit is burning eciently, a visual inspection of the burn grate is re-
quired periodically. The burn grate should sit at against the back wall. Due to the
intense heat that is created, the burn grate can change shapes. There should be no
more than a 3/16” gap from the back wall to the burn grate. If a gap does exist, then it
must be corrected to ensure proper pellet burning. To get to the burn grate see Page
17.
