What Propane Pressure Is Required for DuroMax Dual Fuel Generators?

DuroMax dual fuel generators require specific propane pressure levels depending on the generator’s wattage range.

Providing the correct fuel pressure is important to ensure proper startup, stable operation, and full power output.

Propane Pressure Requirements

Generators 5500 Watts and Below

Generators in this range require:

11 inches of water column (WC)

This pressure level is typical for standard low-pressure propane systems, such as those used with grill-style propane tanks.

Generators 8500 Watts and Larger

Generators in this range require:

At least 3 PSI of propane pressure

These larger generators require higher fuel pressure to support increased fuel demand during operation.

Important Installation Note

Always use the original propane hose and regulator provided with the generator.

The included regulator is designed to properly regulate propane pressure for safe and efficient generator operation.

Using different regulators or hoses may result in:

• Improper fuel pressure

• Poor generator performance

• Starting issues

Common Questions

Can I connect my generator directly to a home propane system?

Yes, but the propane system must provide the correct pressure required for your generator model.

We recommend consulting a licensed propane technician or plumber for proper installation.

What happens if the propane pressure is too low?

Low propane pressure may cause the generator to:

• Fail to start

• Run poorly

• Shut down under load

Do I need a different regulator for larger generators?

Larger generators typically require higher propane pressure (3 PSI), so it is important that the propane supply system is configured correctly.
