Using this burner cap is easy. Simply remove the old burner cap from your Westinghouse or Chef gas stove and place this new one in its place. Make sure it fits snugly. When using the stove, always follow the normal safety procedures as you would with your stove. As for maintenance, after each use, wait for the burner cap to cool down completely. Then, you can wipe it clean with a damp cloth. Avoid using abrasive cleaners as they might damage the matt coating. If you're not sure if this burner cap fits your model, don't hesitate to provide your model number before purchasing to ensure a proper fit.
