Duromax XP15000EH Generator Details

The Duromax XP15000EH is a dual-fuel generator, and a fuel select switch on the front panel sets it to GAS or LPG. When it runs on gasoline, the propane supply has to be shut off. When it runs on propane, the gasoline valve has to be closed. Propane goes in through a regulator and decompression valve mounted on the frame below the OHV valve cover. The included hose connects to the tank with an ACME nut. Leftover gasoline in the carburetor can make the engine run unevenly for a few minutes after switching to propane, so wait until it runs smoothly before you connect any loads.

The control panel has a digital volt meter and hour meter, which shows output voltage and logs operating hours for maintenance. A resettable circuit breaker protects the generator from overload, and an Automatic Voltage Regulator works with the carbon brushes to keep AC power stable. The generator also has a ground terminal, a fuel gauge on the tank and a 3-position engine switch (Start, Run and Off). Rubber motor mounts reduce vibration, noise and wear, and a hoist bar lets you lift the unit with a crane onto trucks or loading docks.

An automatic low-oil shutoff protects the engine, but you should still check the oil with the dipstick before every use. The unit ships without oil in the crankcase. Don't run the electric starter for more than 5 seconds at a time. If the engine doesn't start, wait 10 seconds before you try again. In 120/240 V mode, balance the load between both sides of the circuit as evenly as you can, because an uneven load shortens the breaker's trip time. Don't connect 50 Hz or three-phase loads.

The package includes a spark plug wrench, an oil funnel, engine keys and a propane hose. An optional wheel kit with handle pins is also available. The manual includes a wattage reference chart for common appliances and a table of extension cord gauges by amperage and cord length. Above 5,000 feet (1,500 meters), a dealer should modify the carburetor. Even after that modification, the engine loses about 3.5% of its horsepower for every 1,000 feet of altitude.

The maintenance schedule ranges from checks before each use to service at 12 months or 300 hours. Under it, you clean the combustion chamber every 500 hours and check the fuel tube every 24 months. Inspect the carbon brushes every 250 running hours. The air filter is paper, can't be reused and must be replaced rather than cleaned. To change the oil, use a 10 mm hex wrench on the drain plug, which sits below the oil filler and dipstick cap.

How you store the generator depends on how long it will sit. For storage longer than 30 days, do the following: Drain the fuel tank and the carburetor bowl. Remove the spark plug and pour 2 tablespoons of 10W-30 oil into the cylinder. Remove the battery and keep it on a tender indoors. Don't use gasoline that is more than 30 days old, and always leave at least 1.5 inches of space at the top of the tank. Also, never cover the generator while it's still hot.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Duromax XP15000EH Generator, and we answer them below.


How much oil does the Duromax XP15000EH need?
The crankcase holds 54 fl oz (1.6 L). The manual recommends SAE 10W-30 oil. Don't use oils with additives or 2-stroke oils.

What gasoline should I use?
Use fresh, unleaded gasoline rated 87 octane or higher. Never use an oil and gasoline mixture or gasoline older than 30 days.

How much power does it produce on propane compared to gasoline?
On gasoline, it produces 12,500 W running and 15,000 W surge. On propane, it produces 11,500 W running and 14,000 W surge.

How do I switch between gasoline and propane?
Close the gasoline valve before running on LPG, or shut off the propane before running on gasoline. Then set the fuel select switch to GAS or LPG.

How long can it run on a full tank?
On gasoline, it runs about 8 hours at 50% load on its 10.3-gallon (40 L) tank.

Which outlets are available?
It has four outlets: a NEMA 5-20 (120 V), a NEMA L5-30 twist lock (120 V), a NEMA 14-50 (120/240 V) and a NEMA L14-30 twist lock (120/240 V).

What spark plugs does it use?
The V-Twin engine uses two F6RTC-type plugs, such as the NGK BPR5ES. Set the gap to 0.7–0.8 mm (0.028–0.031 in).

Why won't my generator start?
Common causes are an engine switch set to Off, a closed fuel valve, an open choke, no fuel, old fuel, a dirty or broken spark plug, low oil or a surface that isn't level.

How long should I crank the electric starter?
Crank it for no more than 5 seconds at a time, and wait 10 seconds between attempts so you don't damage the starter motor.

How often should the carbon brushes be inspected?
Inspect the carbon brushes every 250 running hours. They are wear parts and work together with the AVR to regulate output.

Does the generator need to be grounded?
Yes. Run a No. 12 AWG stranded copper wire from the ground terminal to a copper or brass rod driven into the earth. Check your local grounding codes as well.

Can I use it at high altitude?
Yes. Above 5,000 feet, have a dealer modify the carburetor. Power still drops by about 3.5% for every 1,000 feet of altitude.

What does the warranty cover?
Parts are covered for 3 years for residential use and 1 year for commercial use. The emissions control system is covered for 2 years.
