Abstract
An insect guard is provided for guarding against the entrance of insects into the venturi tubes of gas grills which may result in clogging of the fuel flow of the burners of a gas grill. The insect guard includes using a plurality of small openings to define the primary air opening in the venturi tube, and also providing for a close tolerance fit at the connection between the venturi tube and the outlet orifice of the valve such that insects are substantially prevented from entrance into the venturi tube.
