Your Weber Gas Barbecue burner assembly has been
factory assembled, pressure and flame tested. As a safety
precaution we recommend you check the burner alignment:
a) Do the valves fit into the ends of the burners?
Figure 9 (a).
b) Are the ends of the burners under the washers at the
left rear and left front of the cooking box? The screws
are only guides. Do not tighten. Figure 9 (b).
c) Are the wing nuts under the burner assembly hand
tight? Do not tighten with pliers. Figure 9 (c).
If you answered YES to a, b and c, the burners are
correctly aligned. If you answered NO, the burners are
misaligned. Contact your dealer. Do not use barbecue.
