Abstract
A device for rotatably mounting on a mixing tube of a gas burner apparatus. The device includes a perforated shield portion for positioning over an air opening in the mixing tube to prevent insect intrusion therein, and an unperforated portion which partially or completely encloses an air opening of the mixing tube to prevent or limit primary air into said tube. A stop is provided on the device to limit rotation thereof and an extending tab provides for ease of rotation of the device on the mixing tube by providing an accessible surface against which pressure may be applied.
