Generic 6000 LP3250

Generic 6000 LP3250 3250W Genie

The Generac 6000 LP3250 generator is a liquid propane powered generator which is capable of putting out 3,750 watts of surge power with a steady output of 3,250 watts. It is a wheeled unit for ease of mobility. This unit is non-CARB compliant and not for use in California.

Until now if you had a LP powered generator, you had to carry the propane tank separately. The Generac 6000 LP3250 is equipped with a tank holder in the frame itself. This eliminates the problem of carrying the tank separately and the fuel line that goes with it.

Generac has been in the business of manufacturing generators since 1959. It was the first company to make generators for home use and was also the first company to make engines specifically for generators. Generac generators are known for their ruggedness and dependability and the Generac 6000 LP 3250 is designed to let you have power wherever you want it.

Power Output and Generation

This generator has a 212cc OHV engine which runs at 3600 rpm. The engine also has a low oil sensor for protecting the engine and uses the splash lubrication method. . The propane tank holder of the Generac 6000 can carry a 20 or 30 lb. propane tank. With a 20lb tank it can provide power for up to 9 hours running at 50% capacity.

This generator can give out 3,250 watts of continuous power with a surge capacity to handle 3,750 watts. It uses a high performance alternator for smooth and efficient operation.

Electrical output:

The output for 120V is 2 standard duplex plug sets. (4 receptacles). The combined output of these receptacles is 2400W at 20 amps, protected by one 20 amp circuit breaker.

With one L14-20R there seems to be some confusion in the literature as to what can be supplied. The owners manual claims that the twist lock can handle 30 amps at 120V although you are using a 20 amp receptacle. This must be a misprint in the manual as the max stated is 2400W which is 20 amps for the 120V. Then the specification says 27 amp max, which is the generator rating.

The L14 circuit is protected by two 15 amp circuits, so one would believe that the circuit can make it’s 27 amp specification, but only using a 20 amp rated receptacle and recommending a 20 amp cord. It appears Generac may not be playing it safe.

At 240V it will max out at the 3250W at 13.5 amps.

Our guess is that you’re not to likely to be pushing the 120V max on the L14, but there is a chance if you do that you may overheat the receptacle and break the circuit.

Fuel Type and Noise Levels:

The Generac 6000 LP 3250 Generator is powered by Liquid propane which is equipped with a propane tank holder that can hold a 20 or 30 lb. tank of propane.

Typical benefits are safe and stable supply, long shelf life, readily available (raid your gas grill) and lower emission output.

Running at 50% load capacity this generator can run for up to 9 hours on one 20 lb. propane tank.

Oil capacity is 0.6L about 2/3 of a quart. Generic advise on using oil is rather over restrictive. at 40F and above, a straight SAE 30W oil is rec om ended, with a 10W-30 from 40F down to -10F, and a 5W-30 synthetic below -10F. Now since they recommended the grade by expected temperature there may be some flexibility in oil. We would have expected that a 10W-30 would have been good for all ranges above -10F. Hopefully this doesn’t void warranty, but sticking closely to the recommendations would be advised.


Generac doesn’t test the sound level or publish any data. The excuse is that there isn’t any industry standard so the results may be misleading.

I’m calling BS on them. How hard can it be to set up a decimal meter and take readings at various distances and at a idle, 50% and 100% loading. Come on guys, if your big competitors can give a relative level then you should be able to step up and do the same. Just quantify it so that we consumers can make some informed choices. Really we need to go to the dealer to check this out. NICE SALES pitch! Not all of us are up for a weeks worth of investigation around town to make this comparison.

All they will say is that it comparable to other generators on the market. Most owners indicate a relative quietness and more so than some of their neighbors units.

The overall dimensions of the Generac 6000 LP 3250 are 39.5x 23.5x 24.74 inches with the handle down. This size makes it very compact for the output it delivers. The weight of the unit without the propane tank is 137 lbs.

Typical Uses and Needs

The Generac 6000 LP 3250 is an ideal generator to take along for outdoor events, camping or even on job sites. It also is very useful as a back up source of power at home in case of power outages. This generator produces 3,250 watts of electricity continuously, this means that if you have a power outage you could comfortable run most of the electrical equipment in your home. Though you would have to run the higher consumption items one at a time.

As for using it at a job site, this generator can easily take the load to run your power equipment and tools. With its carry on propane tank, large wheels and a handle to move it, makes it very easy to have it located just where you need it.

Display & Control Panel, Start-up

Generac Control Panel

The control panel of the Generac 6000 LP 3250 is very straight forward and easy to understand.

To the extreme left you have the ‘ON/OFF’ switch which controls the operation of the generator. Then you have the 120/240 volt 20 Amp locking receptacle which can supply 120 or 240 volts. This receptacle has a cover which flips up.

Next you have four 120 volt outlets under two covers. These outlet too can supply 120volts at 20 Amps total output for all.

To the right of these power outlets you have two circuit breakers/ reset buttons in case of overload.

Be sure to go back up top and read the output section for some potential issues with using these receptacles.


This generator uses the pull start system (recoil rope) to start the engine. Here are the steps to start the Generac 6000 LP 3250 generator.

  1. Make sure the unit is in a level position.
  2. Unplug all electrical loads from the outlets.
  3. Open the fuel shut off valve on the propane cylinder.
  4. Turn the engine Run/Stop switch to the ON position.
  5. Press the regulator prime button for one to two seconds and release.
  6. Slide the engine choke to the left to the Full choke position.
  7. Firmly grasp the recoil handle and pull slowly until you feel a resistance. Now pull the recoil handle up rapidly twice.
  8. Move the choke handle to the Run position and pull up on the recoil handle two times to start the engine.

Notes: the engine will not start with the choke applied. This is an odd procedure, but it’s intent is to get the LP gas into the cylinder then the engine will start without the choke.

Shut Down

Here are the steps to be followed when shutting down the generator.

  1. Shut off all the loads and unplug all the wires from the generator outlet receptacles.
  2. Let the engine run without any load for a few minutes to stabilize the engine of the generator.
  3. Move the On/Off switch to the Off position.
  4. Close the valve on the propane tank

Care and Maintenance

With proper care and regular maintenance of your Generac 6000 LP3250 you can expect to get many years of trouble free service. It is important to keep the unit free from dust and moisture. Use a damp cloth or brush to to keep the exterior clean.

The cooling air slots and openings must be kept clean and free from being clogged. You must operate the generator in a clean and dry environment where it will not be subjected to excessive dust, dirt moisture or any corrosive vapors.

Here are the guidelines as suggested by Generac to maintain this generator.

  • Change the oil after the first 30 hours of using the generator.
  • Check oil level every time you use the generator.
  • Change oil after every 100 hours of use.
  • Service the air filter after every 50 hours of use.
  • Replace spark plug every season. (always liked this one, cleaning and checking works just as well and spark plugs can go for many more hours than a season)
  • Check valve clearance after first fifty hours and adjust if necessary. Also then check it after every 300 hours of use.
  • If the generator is not being used, it needs to be started every 30 days and run for at least 30 minutes. (good practice, but I’m betting you can stretch it.)

If the generator is subject to heavy usage change oil and air filter every month. Also if you are not going to use the generator in the next 30 days, the manufacture indicates you should drain the oil and refill it with fresh oil. Also the spark plug needs to be removed and about ½ ounce of engine oil poured into the cylinder. Plug the spark plug hole with a rag and pull the recoil handle a few times to lubricate the piston rings and cylinder bore.

Consumer Comments

The Generac 6000 LP 3250 generator scores 4 out of 5 stars on Amazon. Most of the people who bought this generator were very happy with its performance. They liked the fact that this generator ran on propane which they found easy to store as well as in times of storms they could get their tanks replaced much easier than standing in line at a gas station for gas if they had a gas generator.

They also liked the fact that the propane tank holder was a part of the unit. One customer summed up this unit saying: “Powerful well built piece of equipment. Can be rolled to any location easily, all switches and receptacles are accessed and the propane model runs clean.”

Another indicated that this generator will do everything he needed in an emergency and loved the idea that he wouldn’t have to stand in gas lines at a gas station.”

On the negative side the complaints were with customer service issues and in a couple of design flaws, but overall these are few compared to the majority that have had good experience with the basic machine. In general they are also complaining that Generic reputation is starting to drop due to the outsource of assembly and manufacture in China. Especially noted was the plastic tank holder and bad design and construction.

Pros & Cons


  • It runs on Propane which is a much cleaner fuel than gasoline and it is also much easier to store and has a safe and stable shelf life.
  • It has covered outlets for protection and circuit breakers to protect it in case of overloads.
  • It has a durable frame which incorporates a tank holder so that you do not have to carry the tank separately.
  • It runs for 9 hours on a 20 lb. tank of propane at 50% output capacity.
  • It has solid 9.5 inch wheels and a locking dolly style handle for ease of movement.
  • It has a low oil shut down system that prevents engine damage in case the oil runs low.
  • It has a splash lubrication system and a high performance alternator to give maximum power at all times.
  • It is much quieter than gas generators of the same size.
  • Storing LP gas is easy and multiple tanks can be used.


On the negative side there were a few issues that current owners noted.

  • To change the spark plug or adjust valve clearance you have to take the housing apart.
  • The pull rope to start the unit gets frayed after a few times of use. It is at a bad angle for use.
  • Sometimes it is difficult to start the engine. Primarily dealing with the choke and starting instructions. See starting procedures for information.
  • You are supposed to start the engine every 30 days for 30 minutes when not in use. This uses up propane from the tank and you do not have a full tank in case of emergencies.
  • With LP tanks it’s not easy to determine the remaining fuel, unless you are lucky enough to have a gauged tank. (with a weight scale you could get an indication) Some Weber Grills have this included, might be a good design change Generac.)
  • No electric start on this model.


This generator has a list price near $760.00, but you can find this generator for less on amazon at closer to $600, check it out here: Generac 6000 LP3250 3,750 Watt Liquid Propane Powered Portable Generator

For a LP powered generator which delivers 3,250 watts of continuous power this is a very reasonable price. This generator from a company that deals mainly in generators is a good value for its price.


There are many accessories available for this generator that might be useful in helping you both maintain as well as run this generator. You can find a generator cover to help you protect the generator from the elements when not in use.

Also available is a propane level indicator and safety gauge for your propane tank.GasWatch TVL212 Propane Level Indicator and Safety Gauge

When it comes to a generator that can deliver 3,250 watts of continuous power and is fueled by propane the Generac 6000LP3250 is one of the best you can buy.

It comes with many conveniences that make it not only easy to use but easy to transport and move around to where you need it. This is one of the few LP powered generators that can carry its own tank and has solid 9.5 inch wheels with a foldable handle that lets it deliver the power you need where you need it be it at home, a camp ground or at a job site.

By using propane as fuel it makes it very easy and convenient to store fuel without worrying about it getting old or stale. Besides the convenience of propane means that you can get a refill almost anywhere without having to worry about the long lines at the gas stations during emergencies.

Our reservations on this is some comments regarding poor design flaws. Namely the rope pull is at a bad angle and some have experienced fraying and breakage. Some of the assembly from the Chinese has been less than stellar, but in general fairly good. The tank holding bracket seems to be giving some folks poor performance on assembly and usage.
