6. If your grill is equipped with both open-flame and Sear Burners, verify you have the correct orifice
for each kind of burner. The orifice size is stamped on the body of the orifice. Consult the chart at
the end of this manual for what size is used on each burner type. This is also a good time to clean
and inspect the burners for clogged ports, debris, spider webs, etc.
Install the orifices slowly to avoid cross-threading and damaging the threads. The orifice will become
noticeably harder to turn as you proceed. Make frequent visual checks of the orifice as it goes
onto the valve. As shown below, the orifice is nearly bottomed-out on the valve body. You want to
tighten all the orifices equally so they are all seated the same distance. Use a burner to check the
orifice is properly seated. As shown, the burner should fully seat with the orifice protruding into
the air shutter as far as possible. The burner should rest flat on the burner hanger at the back of the
firebox.
CHANGING ORIFICES

5. Before removing the main burner orifices, take a visual note as to how far the orifice is installed onto
the valve body. The orifices are removed with a 1/2” deep socket wrench. Use even pressure to
break loose the old orifice and remove from the valve.
