FIREBOX AND BURN GRATE ASSEMBLY MAINTENANCE
It is recommended that the firebox assembly is regularly inspected to be certain that it remains free of ash
and debris which will ensure proper performance. The firebox is a fully welded structure that carries the
burn grate and channels the combustion air. The firebox is bolted to the cooking chamber floor. The seams
on the hopper wall and the floor 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 firebox 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 for 24 hours before use. We recommend using Permatex 81160 high temperature silicone or
Sure Bond SB-188
.
The seating of the burn grate into the firebox is critical for proper grill performance. Begin by resting the
right hand side of the burn grate on the fire 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 floor and sides of the burn grate
for any blockage or build-up. Using a wire brush or flat-head screwdriver, scrape off 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 efficiently, a visual inspection of the burn grate is required periodically. The
burn grate should sit flat 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
(FIG 58)
. If
a gap does exist, then it must be corrected to ensure proper pellet burning. To access the burn grate see
Page 33.
