Are your products EPA Certified? Yes. Selling Non EPA approved product is illegal in the US and the result can be disastrous to the companies doing it (see Volkswagen settlement here) and the customer that unwittingly purchase product that gets recalled. All of our kits and converted generators have been tested as new generators or kits to be installed in specific generators (our EPA manufacturing designation is NEG) and approved by the EPA for sale as kits and converted generators. The regulation for small non-road spark-ignition engines and equipment kits and generators is CFR Title 40, Chapter I, Subchapter U, Part 1054 found HERE. kits are addressed specifically in Part 1054.645 found HERE,  The testing required for certification is per Part 1065 “Calculations, equipment and data” found HERE, and a new mandatory bond starting at $25,000.00 must be posted by all manufacturers of generators, kits and accessories intended for modifying any fuel system in any way.  This process is very expensive and can take up to a year to complete but is legally required for each generator class.  Here are links to our certificates by engine family: GNEGS.0991US, GNEGS.1961US, GNEGS.3892US.  Does Propane and/or Natural Gas still produce deadly ‘CO’ Carbon Monoxide? YES.  Although propane and natural gas tend to burn cleaner inside the combustion chamber, they both still produce almost the same deadly carbon monoxide output as gasoline.  Propane and natural gas generators must never be used inside a home or business, and must never be used closer than 5 feet from ANY opening including shut windows (still considered an opening).  They should also never be used under decks or on porches and most fire marshals in fact recommend never operating a generator closer than 10’ to your home.  Always ask your local inspector or fire marshal if you are unsure.  You should also, by code and for safety, have a working CO detector in any bedroom adjacent to where a generator will be running.  The bottom line with CO is that you or your family can quickly get too disoriented to save you or themselves if you fail to take the necessary precautions ahead of time. What’s wrong with “generic” propane kits? Besides risking any warranty help once the seller is shut down from being fined up to $37,000 per day per generator by the EPA, the number ONE call we get is to help diagnose or “tune” propane kits bought from other companies that were not factory tuned and can’t get them to run correctly!  Basically, you probably don’t have the correct equipment on hand to do it, it won’t meet EPA and not doing it correctly could lead to overheating in the combustion chamber (too lean) or carbon fouling and sputtering (too rich).  Either way, the result is that you can quickly ruin your very expensive generator by trying to save money with a lower value kit.  We only sell kits and modified generators with pre-set orifices for properly metering fuel. They are not adjustable, are designed for optimum performance and to meet EPA emissions levels.  We test every generator before shipment over the entire load range, including ECO mode.  This means we have to limit our product offering to only those generators we have engineered systems for, but the benefit to you is that you know your system is fully approved and will work right out-of-the-box. Why Propane? 1. Gasoline ages in as little as 6 months, and is virtually unusable (varnish!) after just a few years, whereas propane can last virtually forever 2. Ethanol in gasoline absorbs water and causes deterioration of nonmetallic parts like gaskets.   If you live in Missouri or Montana you can buy 93 Octane ethanol free gasoline. 3. Delicate components inside your engine’s needle valves and ports inside the carburetor get gummed up quickly as the gasoline ages and routinely don’t work if not cleaned annually. 4. Gasoline is dangerous to pour, making it very dangerous to re- fuel a hot engine. 5. Gasoline tanks typically only hold 4-5 hours of fuel, but a single 20-20lb propane tank can run a lightly-loaded EU2000 for an entire 24hrs - that’s a once a day refueling vs getting up in the middle of the night and going outside in 10deg. to keep the heat on! 6. Your Oil will last longer with propane because it burns cleaner and pollutes the oil less from combustion gas blow-by. 7. Propane is considered much safer to store and transport. 8. Propane tanks can be exchanged during outages, whereas gasoline requires power to pump. 9. Most people already have a barbecue grill with at least one handy tank ready.   What size propane tank should I use? HERE is a link to our propane tech note on tank sizing.  The two main factors that effect propane tank size are temperature and load.  In general, to provide enough propane vapor to run your generator at or near freezing temperatures (or above), we recommend a minimum of a 20lb tank for up to 2000Watts, a 30lb pound tank for up to 3000Watt and a minimum of a 60lb tank (or two 30lb tanks together) for operation up to 7000Watts.  For operation at or near zero, we recommend a minimum of a 30lb tank for up to 2000Watts, a 40lb tank for up to 3000Watts and 80-100lbs for up to 7000Watts.  Please note that these numbers are based on peak usage and not average.  For instance, the Honda EU2000i is rated at 1600Watts for long-term use and the Honda EU7000is is rated at 5500Watts average.  When in doubt, go up in tank size, double up, or in extreme conditions, use a tank warmer. Will propane work in cold weather? Yes if you size your tank correctly for your load.  You can also simply position your tank a foot away from the output in extreme cold conditions, where the extra heat from the exhaust will provide energy for faster internal vaporization.  CAUTION should be used here, though, as you don’t want the tank right up again the exhaust. Will our generators work on Natural Gas? Yes some of our models come with a changeable orifice to go between Natural gas and Propane (both operate at max 1/2psi or 13”w.c.). However, some states require all gas appliances, indoor AND outdoor to have a UL or equivalent listing (such as Massachusetts) before it can be connected to a home’s natural gas supply.  In general, most states follow NFPA 54, which is silent on this for outdoor portable appliances such as heat lamps and barbecue grills but if in question always check with your town’s local inspector in charge. What happens if my tank runs out of propane while I’m at work? Not a problem.  Just simply hook up a new tank when you get home and start back up.  It’s as simple as changing your BBQ grill tank.  Just remember to turn off the valve on the empty tank. What maintenance should I do on my propane or natural gas generator? Like any propane device, you should periodically check all connections on the hose for leaks using soapy water (not a match!), and you should keep the dust caps on the quick-connect fittings at all time when not in use.  There is a second regulator inside the generator, that if dirt and debris gets inside, may not function correctly and could leak if you leave your gas tank on.  It will then need servicing by us or a qualified propane mechanic / gas fitter.  In addition, we recommend you follow the OEM manual for generator maintenance. How far should I place any generator from my house when it’s running? THIS IS IMPORTANT!!  The National Fire Code requires at least 5 feet clearance from any windows and doors or any other “openings” or any outside wall that has a fire rating of less than 1 hour (non-brick for instance), but almost all fire officials strongly suggest 10’ (which is why we put on a 10’ line cord).  This is because all generators produce deadly oderless carbon monoxide CO that can penetrate these openings without you knowing (read about early CO poisoning signs on web).  You should also NEVER operate a generator in a garage or confined space.  In addition, it can be against state and federal codes to enclose portable generators.  You should also always install and maintain a CO detector in the closest bedroom to where the generator will be running.  Always consult with your local inspector or fire department for up to date rules and regulations to keep you safe. What oil and spark plug should I use? We recommend 10W-30 (5W-30 if temp goes below 0 deg F) fully synthetic motor oil for the best lubricate the valve stems and other engine parts over regular oil as propane burns slightly hotter at full peak load  We recommend using the original Honda factory spark plug gap of 0.028” for overall best performance and power.  Here is our latest recommendation for spark plugs as of Jan 2024 for each unit: EU2000i/2200i NGK CR5HSB EB/EG2800i NGK BPR6ES EU3000is Champion RC12YC (or NGK IFR6Q- G) EU7000is NGK IFR6Q-G (#5648) NOTE: this is essential for smoother operation in ECO mode for natural gas Do the latest Honda EU2200i and EU3000is generators have an hour meter? Yes, on late model “A” 2200’s and newer EU3000is flash they green output LED at startup to show status as follows: Less than 100 hours 0 blinks after start 100 to 200 hours 1 blink after start 200 to 300 hours 2 blinks after start 300 to 400 hours 3 blinks after start 400 to 500 hours 4 blinks after start Over 500 hours 5 blinks after start Can I run two EU2200i’s at the same time from my camper’s 1/4” propane quick disconnect? Yes, if the connector is only a few feet from the tank and if you are just using the two to start a 12,000 or 14,000 BTU A/C unit that normally run at approximately 1600 Watts once started.  No, if you want to run both generators in total above this power for any length of time or have your 1/4” quick disconnect more than a few feet away.   In this case you should have your line upgraded to 3/8” i.d. with a 3/8” quick disconnect installed and or use our 12’ x ⅜” dual output hose with our ¼” to ⅜” adapter. Do I need to ‘break in’ my generator on gasoline first? No.  We are asked this quite often and believe it’s meant to get customers to test their base generator first for potential generator warranty claims against the original manufacturer before installing non EPA certified conversion kits that were not specifically designed for that engine.
