This kit contains the parts and tools you need to convert Ooni Koda 16 from its default gas fuel (propane) to run on natural gas from a fixed natural gas line. Detailed and fully illustrated instructions are included to help you complete the conversion within just one hour. Apart from the parts supplied, youll also need a 19mm (3/4") wrench, a 12mm (1/2") wrench, and a Phillips head screwdriver. You'll also want to ensure your natural gas supply line termination has a 3/8" NPT male thread and that your gas pressure is 7iwc. Depending on your local gas code, you may also need a quarter turn valve installed on your gas line. We recommend you consult with a local gas engineer to make sure you've got everything you need for your specific requirements. This kit is US market exclusive and not available in other markets.
