  1. Turn the Lever towards a tank.
  2. If there is propane in the tank, the indicator will go clear.

  4. When the tank runs out of propane, the indicator will show RED and the regulator will automatically switch over to pulling propane from the other tank.
  5. Rotate the lever to the other side and the indicator will go clear again.
  6. This will allow you to remove the empty tank and get it refilled.
  7. Propane will flow from the second one while you get the first one refilled.

    Reviewed in Canada on September 26, 2023
    Five to ten minutes to install, don't tork to much the pipes screws, plastic is not very strong. Don't forget an output adaptor (fitting) and a roll of pink Teflon (you need pink Teflon for propane, never use the white one!!!). The selector is very useful 👌, you can change the empty bottle without having to re-light the pilots for hot water 💧.
