How to Run a Westinghouse Dual Fuel Generator on Propane

Step-by-step: connect a propane tank to your Westinghouse DF generator, switch fuels, and know how much power and runtime to expect on LPG.

Every Westinghouse model with "DF" in the name runs on gasoline or propane. Those are the iGen2550DFc, iGen2800DFc, iGen4000DFc, iGen4000DFcv, iGen5000DFcv, iGen12000DFc, WGen3600DFcv and WGen5300DFcv. The iGen12000TFc adds natural gas.

What you need

  • A propane cylinder. A standard 20 lb grill tank is the most common choice.
  • The LPG regulator and hose. These come in the box with the iGen2550DFc, iGen2800DFc, iGen4000DFc and iGen4000DFcv.

Steps

  1. Place the generator outdoors on level ground, well away from windows, doors and vents.
  2. Close the tank valve, then thread the regulator onto the tank and the hose onto the generator's propane inlet. Tighten both by hand.
  3. Open the tank valve slowly and check the connections for leaks with soapy water. Bubbles mean a leak.
  4. Set the generator's fuel selector to propane (LPG).
  5. Start the generator as normal: recoil, electric or remote, depending on the model. Let it warm up before adding big loads.
  6. To shut down, close the tank valve first and let the generator run out of propane in the line. Then switch it off.

What changes on propane

  • About 10% less power. The iGen2550DFc drops from 1,900 to 1,700 rated watts. The iGen4000DFc drops from 3,300 to 2,970.
  • Longer runtime. The iGen2550DFc is rated up to 25 hours on propane at 25% load (11 on gasoline). The iGen4000DFc is rated up to 17 hours (7 on gasoline). Actual runtime depends on tank size and load.
  • Easier storage. Propane doesn't go stale and gum up the carburetor.
