Using this ignition pack is easy. First, make sure your gas oven or stove is turned off. Then, find the mounting area with holes 122mm apart on the back of your appliance and attach the ignition pack securely. Connect the 2 X 6.4mm spade terminals to the input and the 6 X 2.8mm spade terminals to the appropriate outputs. When you're done, turn on your appliance to see if it ignites properly. As for maintenance, keep the ignition pack clean. Wipe off any dirt or debris regularly. If you notice any issues, like it not igniting or strange noises, stop using it right away and check the connections. Also, even though it's new old stock and shop - oiled, don't use harsh chemicals to clean it. This will keep your ignition pack working well for a long time.
