Burner Shutter Adjustments
The gas burner shutters are adjusted at the factory for
your convenience. The adjustments are:
(1) full open for natural gas models
(2) half open for liquid propane units
If further adjustment is desired, please follow
this procedure.
1. Always judge a flame with LA-VA-GRATE

, briquettes
and SEAR GRID

in place.
2. Loosen shutter locking screw (See Fig. 20) and close
shutter until yellow tip appears in the flame.
NOTE: It is sometimes necessary to back the burner off
the orifice to adjust the shutter. See Page 34 on releasing
burner from supports.
3. Open shutter until desired blue flame appears.
4. Tighten locking screw enough to hold shutter securely
in place (do not over tighten and strip
the threads).
NOTE: Reinstall burner over orifice (See Page 37)
if removed.
