When you use a gas BBQ, you need a gas pressure regulator. If you don't handle gas with care, it can be very dangerous. That's why it's essential that you have the right gas regulator. A gas pressure regulator ensures that you get a constant gas pressure. In most cases, the BBQ you ordered doesn't include one by default. Gas barbecues in the Netherlands work on 30 mBar, but a gas BBQ in Belgium works on 37 mBar.
