If the burner you have purchased was installed on a Subito Cotto oven, it set up during installation, but due to the vibrations it was exposed to during shipment we require that your or your installer perform a leak test before using the unit. Your burner connection is a “G” BSP ½ inch male port. If you purchased a regulator with your burner you will be able to connect it directly, if you did not purchased a regulator or if you are going to use the burner with natural gas you will need a 1/2” G Thread (BSP) Female to 1/2” NPT Male Connector. We would be happy to supply you with technical publications that will help you installing your Avanzini burner into your new oven or optimizing its performance if purchased in conjunction with one of our ovens.
