6. Attach the burner box to the base cabinet using the four (4) 1/4x20x1" pointed
screws and the four (4) 1/4" teflon washers from the base cabinet kit (a). The
screws with the washers directly underneath go through the four holes in the
bottom of the burner box and engage in the caged nuts in the top of the base
cabinet (b). Engage all 4 screws before tightening any of the four (c). In order to
get the screws in the mounting holes of some grill models, it may be necessary
to carefully rotate the burners out of the way of the holes. Unscrew the burner
locking screw to release the burner.
