1. Remove the grates and flame tamers.
2. Remove the cotter clip that hold the burner in place. Set
the clip aside.
3. Remove the burner from the grill by lifting the burner out.
4. Use a 6 mm socket and wrench or 6 mm nut driver to
remove the LP brass orifice from the end of gas valve. The
main burner NG orifice is located behind the LP orifice, so
no additional orifice needs to be installed.

IMPORTANT: Check that the LP orifice is properly
removed inside of the burner opening.
5. Reinsert the burner by sliding the middle tube of the gas
burner over the gas orifice and reattach using the cotter
