BURNER ADJUSTMENT

NOTICE

It may be necessary to adjust the burners periodically, to compensate for variables in gas characteristics. If you notice the burner flame pat- tern is irregular (Refer to Figures 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. (Fig. 20)

Use a screwdriver to loosen the locking screws. Open the shut- ter 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 adjust- ments.

WARNING

Always allow sufficient time for the Grill to cool to a safe tempera- ture before handling or cleaning any of its components.

If burners are removed for cleaning or adjustment, always confirm that they have been reinstalled correctly over the valve outlets. (Fig. 21) The valves should extend into the burner venturis 1/4” minimum.

NOTICE

Similar adjustment can be made to Rotisserie and/or Side Burners, if so equipped.
