Using this burner cap is easy. Just place it on the appropriate burner of your Westinghouse, Simpson, or Chef gas oven or stove. Make sure it fits snugly. When using your stove, keep in mind that although the cap is made of solid cast iron with a sintered enamel coating, it can still get hot. So, always use heat - resistant gloves when handling it. For maintenance, after each use, let the cap cool down completely. Then, you can gently wipe it with a damp cloth. Avoid using abrasive cleaners as they might damage the enamel coating. If you're not sure if this cap fits your model, check your model number before you buy. That way, you'll have a smooth and hassle - free cooking experience.
