  6. What is needed to connect a 20 pound propane tank

    1 answer

    1. For this heater you'll need a low-pressure propane regulator and a hose. We recommend the F273684 kit, but any matching hose and regulator will do.

  7. Does this heater have a hose? If not what fitting or hose does it need? Does it have an internal pressure regulator or does the hose need a regulator?
