If you want a natural gas patio heater, it’s best to buy one that’s meant to run on natural gas. However, some models of propane heaters come with connections to natural gas lines. If not, the best solution is to buy propane for the natural gas conversion kit. These kits include a quick-connect hose, which should be made out of 100 percent rubber and durable connectors. You need to make sure the size is compatible with your current heater- many kits come with several connectors. You’ll also need thread gauges and a wrench. Make sure you follow directions completely.
