Weber 1200 Owner's Manual

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.
