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 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
3. 3 Hold the Start Stop switch in its STOP position until engine comes to a complete stop APPLYING LOADS TO GENERATOR When applying electrical loads to the generator observe these guidelines CAUTION If the engine does not start after it has been cranking for 15 seconds release the start stop switch and try again Holding the switch for longer than 15 seconds can damage the starter motor Before applying electrical loads let the generator stabilize and warm up for a minute or two DO NOT overload the generator LET ENGINE STABILIZE The generator supplies correct rated voltage only at proper governed speed Some electrical appliances may be extremely sensitive to voltage Incorrect voltages can damage those appliances If electrical loads are applied at reduced operating speeds such loads imposed on the engine when sufficient power is not available may shorten engine life Never turn ON electrical loads until after the generator engine has started and stabi lized ON speed DO NOT OVERLOAD THE GENERATOR You can read the rated wattage amperage capacity of your gen erator on the generator data decal see Identification Record on Page 3 Applying electrical loads in excess of the units rated capac ity will cause the engine generator to automatically shutdown To avoid overloading add up the wattage of all connected elec trical lighting appliance tool and motor loads This total should not be greater th
