Maintenance
BURNER ADJUSTMENT
NOTE: It may be necessary to adjust the burners
periodically, to compensate for variables in gas char-
acteristics. 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. 20).
• 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. 21). The valves should extend into
the burner venturis 1/4” minimum.
NOTE:
Similar adjustment can be made to Rotisserie
and/or Side Burners, if so equipped.
