Material Safety Data Sheets

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 on page 7 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.
