Keeping a close eye on everything in your kitchen, be it a commercial one or your cooking corner at home, isn’t always possible, which is why all kinds of little bits and pieces have been designed to help keep things in line. Hi-limits are the unseen parts that help monitor how much gas is being used, as well as the output every time you turn on a piece of equipment, and making sure yours are in working order is essential. These little guys are often the culprits when something gas-related goes awry, which is why keeping one or two extra hi-limits on hand can make a huge difference.
