A gas-fired pizza oven can be used outside as long as it is properly installed and if it requires a gas line connection. In fact, some gas-fired pizza ovens are made exclusively for outdoor installation and use.
Outdoor gas-fired pizza ovens come in two types of models. Built-in models are those that are built into a structure. Often, it is a brick surround, though this is not always the case. These types of ovens have a typical gas line connection and can be professional installed or installed as a DIY project by those who are familiar with installing gas appliance. Cart top models look very much like gas grills. Like gas grills, these models run on refillable portable tanks and require no special installation.
