Fuel Type, Fuel Usage, and Fuel Pressure Requirements

Fuel type

• Natural Gas (NG) or Liquid Propane (LP)

Fuel consumption — 22 kW

Natural Gas

• 1/2 load: 221 ft³/hr (6.27 m³/hr)

• Full load: 311 ft³/hr (8.80 m³/hr)

Liquid Propane

• 1/2 load: 89 ft³/hr (2.45 gal/hr / 9.28 L/hr)

• Full load: 135 ft³/hr (3.71 gal/hr / 14.03 L/hr)

Required inlet fuel pressure (at generator fuel inlet, all load ranges)

• NG: 3.5–7 in. water column (0.87–1.74 kPa)

• LP: 10–12 in. water column (2.49–2.99 kPa)

Fuel piping must be properly sized for full-load operation and installed to applicable code.

Transfer Switch Options (Unbundled vs Bundle)

Unbundled (Generator only)

Best if you’re matching with an existing or separately selected transfer switch / load management design.

Bundled (Recommended complete system)

Bundled models include a 200A service-rated transfer switch with features such as:

• Includes fuse control module (FCM) standard

• Integrated surge protection

• Electrically operated, mechanically-held contacts

• Rated for aluminum and copper conductors

• NEMA/UL 3R aluminum outdoor enclosure (indoor/outdoor mounting flexibility)

• Transfer switch weight: 39.0 lb (17.7 kg)

Energy Management / Load Managers are sold separately when needed to optimize startup loads and help avoid overload conditions.
