Using this ignition electrode is easy. First, make sure your Westinghouse gas stove or oven is turned off and cooled down. Then, connect the 1 - metre lead with the insulated 2.8mm terminal to the electronic ignition module. Attach the electrode to the appropriate place in your appliance as per the model's design. When you're done installing, turn on your stove or oven to test if the ignition works. As for precautions, always check your model number or sales code before purchasing to ensure compatibility. And don't try to install it when the appliance is hot to avoid burns. For maintenance, keep the electrode clean. You can gently wipe it with a soft cloth from time to time to remove any dirt or debris that might affect its performance. If you notice any issues like poor ignition, don't hesitate to contact a professional for further inspection.
