Generac NP-50LPG Recreational Vehicle Generator

FUEL REQUIREMENTS

The “NP” series generator is equipped with a liquefied petro- leum (LP) gas fuel system. LP gas is usually supplied as a liquid in pressure tanks.

“NP” series generators require a “vapor withdrawal” type fuel system. This type of gaseous fuel system uses the vapors forming above the liquid fuel in the storage tank. Air temper- ature around the storage tank must be high enough to sustain adequate fuel vaporization. In colder climates, you may need to use an independent heat source to be sure the fuel suffi- ciently vaporizes in the storage tank.

LP gas may consist of propane, butane or a mixture of two gases. Using fresh HD-5 LP is recommended. Fuel should not contain more than 2.5% butane. Propane vaporizes at tem- peratures as low as -20°F (-29°C), but butane returns to its liquid state when the temperature drops below about 32°F (0°C). For that reason, a higher ratio of propane is desired in the gas mixture when temperatures drop below freezing.

FUEL CONSUMPTION

(CUBIC FEET PER HOUR)

The following lists the approximate amount of fuel the unit con- sumes at 100% rated load. Actual fuel consumption may vary depending on BTU content of fuel, applied load, ambi- ent conditions, engine condition, etc.

Propane 47 cubic ft. per hour

ENGINE OIL REQUIREMENTS

Use a high quality detergent oil classified “For Service SF” and with an oil viscosity rating of SAE 10W-30 oil. Do not pour in any additives to the recommended oil. Engine crankcase capacity is 1.5 U.S. quarts (1.4 liters). See MAINTENANCE section for oil level check and filling procedures.
