Burner Adjustment

NOTE : It may be necessary to adjust the burners periodically,
to compensate for variables in gas characteristics. If you notice
that the burner flame pattern is irregular (see Figs. 9a, 9b &
9c) it may be necessary to adjust the air shutter opening at the
front of the venturi tubes. The shutters are accessible under the
control panel at the front of the Grill (see Fig. 21).
Use a screwdriver to loosen the locking screws. Open the
shutter just enough to achieve the desired soft, blue flames.
Make adjustments in small increments and allow the burner to
come up to operating temperature (10 min.) before making
further adjustments.
If burners are removed for cleaning or adjustment, always
confirm that they have been reinstalled correctly over the valve
outlets (see Fig. 22). The valves should extend into the burner
venturis approximately 1/4".
