High Altitude Operation
This generator comes with computer controlled electronic fuel induction for natural
gas and propane operation and computer controlled electronic fuel injection for
gasoline operation. This, along with the built in absolute ambient air pressure the on-
board computer will automatically correct for altitude between sea level and
approximately 0,000ft. Note that engines in general will lose between 2.5% to 3%
of engine power for every 000ft above sea level. At 0,000ft the maximum power
on propane, for instance, will be approx 4,900Watts vs 7,000Watts at sea level

To START your generator from propane BBQ tanks, connect the supplied regulator hose to
both the propane tank and generator. Slowly turn on the propane tank. If you hear a “ting”
sound as you turn on the BBQ valve you may have actuated the tank’s excess flow valve. If
this happens, either wait a moment for it to automatically reset or you will have to turn off tank
valve and repeat this step slower. To connect to larger propane tanks with regulators already
on them or natural gas connect the straight-through hose to both the generator and supply line
quick disconnects.
Note that your generator has a secondary propane & natural gas fuel lock-off solenoid inside.
Because of this, you must jump start this generator with a car battery or equivalent if needed.
Also, note that it may take several successive attempts to start your generator by any means
based on your fuel hose length This is because there will be air trapped in the hose when first
connected that will have to work through before the generator receives pure fuel.
To STOP your generator, we recommend that you turn off what you are powering (generator
load), then turn off the gas supply, then turn off the key. This is a best practice when possible
to minimize potential accidents and removes the smell of fuel from your hose when
disconnecting it.
How to start your generator and STOP your generator
Troubleshooting
Generator won’t start
. Make sure the generator’s fuel selection switch matches the fuel you are using
2. Check that your battery is charged. If the display turns off or you hear just a “clunk”
sound but it does not turn over, your battery is either bad or not charged enough. If
needed, you can either jump start the battery or use a battery charger to charge it.
3. Check that propane tank hose connection is fully screwed onto tank tightly.
4. Turn your propane tank off then back on slowly to check/reset tank excess flow valve.
5. Check that your air cleaner element is not flooded with oil. This can happen if your
generator tips over. If it is, squeeze filter between paper towels, then properly
dispose of oily paper towels. (oily rags can spontaneously combust in garbage or in
pile - hang until dry, then soak with water and detergent before discarding)
6. Check that your tank isn’t empty, or near empty or has tipped over. If your propane
tank tipped over, the tank valve may freeze up. Return tank to upright position and let
it sit for a while without use to let valve thaw and/or drain.
7. Check the status lights on Genconnex EFI control box located at the bottom of the oil
fill side door. The green power light should be on when the start button is pressed.
There are two lights to show which fuel the EFI controller senses you have selected,
a light that lights if the O2 sensor signal is poor or too low, and a light that lights up if
the altitude sensor is above 0,000feet or damaged.
Safety Information
NOTICE:
This section is intended to augment safety information in the original Honda
OEM manual. Read the Honda Owner’s Manual before operating
this generator.
DANGER:
Failure to follow instructions may result in explosion or fire causing
property damage, serious injury or death
DO NOT attempt to use damaged (including but not limited to kinked, cut, chewed or plugged)
equipment and hoses. See your local LP or Natural Gas dealer for repairs.
DO NOT operate a generator inside your home, garage, or place of business. It must be
used outdoors at all times with all nearby doors and windows closed. The National Fire
Code requires the generator be a minimum of 5 feet from any structure and highly
recommends a minimum distance of 0 feet to any openings including windows and doors.
DO NOT attempt to make repairs yourself
DO NOT connect to non-approved tanks or systems
DO NOT use an open flame to check for gas leaks
DO NOT perform your own gas pipe installation or repair without a proper license
DO NOT let fuel hose/regulator or tank come in direct contact with exhaust pipe
DO NOT make any alterations or modifications to any natural gas or propane supply. You must
use a licensed gas fitter/plumber and follow all state and local codes.
DO NOT store propane tanks in your home or garage etc.
INSPECT all hoses and connections prior to use

PROPANE TANK SIZING GUIDELINES
Propane tanks vaporize the fuel inside at a rate based on the rate of heat absorbed from the
tanks steel shell. The colder the temperature the slower the propane vaporizes until at some
point the generator is requiring more vapor per minute than the tank can produce. This will
cause the generator to turn off or run very poorly.
. Make sure both side doors are latched close and spark plug was gapped right.
2. Make sure the battery door is installed and screwed close. Note there is a cutout
in the top of the door for remotes and external battery leads.
3. Do not start your generator in ECO mode. Let it warm up 5 minutes first.
Generator runs rough

32
. DO NOT START YOUR GENERATOR IN ECO ‘ON’! Turn it off before every
start until 2minutes when warm and 5 minutes cold. We also recommend ECO
mode only if your load will not be fluctuating greatly or running motors. This
prevents a brown-out and possible damage to your equipment as the
generator tries to quickly increase RPM’s to handle the sudden changes.
2. Make sure your generator’s battery is fully charged This generator
requires a charged battery to open the internal fuel lock-off solenoid to start.
The pull starter can only be used if a 2Vdc- Amp minimum power source is
applied to the solenoid. We suggest leaving your generator’s battery plugged
into a smart-charger/trickle charger when not in use so it remains in a fully
charged state, or to start it and run it for a few hours every 2-3 months.
3. Side doors and battery compartment door must be latched shut The
EU7000is engine draws in a combination of air for combustion through the
battery compartment door vents and from the pressurized enclosure based on
the battery door’s design. If the battery door is removed or one or both side
doors are open the generator will not operate correctly or cool correctly and
the turbulent air inside the enclosure may lead to EFI over-control, especially
in ECO mode. Note in Honda Manual where a cutout is, in the top of the door,
for remote control and battery extension cable access to enable the door to
stay closed.
4. Do not attempt to cold start loads greater than 75% of full load de-rated
for altitude You can damage the engine and or load. Let the generator
warm up for 5 minutes before applying full load on any fuel.
5. Change fuel selection switch only when the generator is turned off.
6. Do not replace your generator’s battery with a different brand or rating
Lesser batteries have been found to have a much lower cold cranking ability.
7. You may need to add a secondary battery in parallel with the Honda
battery for cold starting below 15Deg F. The OEM battery may not have
enough cold cranking amps to turn over a cold soaked engine below approx.
5degF. Store the generator indoors where its warmer or we recommend our
“GXA EU7000is Battery Extend Kit” that enables you to connect an additional
car battery for starting. 0W-30 fully synthetic motor oil must be used for
extreme low temperatures along with Honda’s cold weather breather tube kit.
8. This is a fully EFI controlled generator. There is no choke.
9. When possible, turn the generator off by turning off the propane tank or
natural gas supply valve. This is a best practice for being safe with all
propane/natural gas outdoor appliances.
0. We recommend that you always put the caps back over the quick-disconnects
immediately after use to prevent contamination or water from entering the unit.
Tips before starting Use & Maintenance
The proper fuel pressure for your generator
Your generator comes pre-set from the factory to run from low pressure natural gas and
propane at 7- ” w.c. equivalent to max /2psi (also referred to as standard household
pressure). DO NOT connect your generator directly to a propane tank without the
proper regulator or to an intermediate 0- 5psi regulator often found on large tanks.
How to connect your generator to a propane tank
) Set up your generator outdoors on a hard level
surface such as a driveway or concrete patio at least 5’
from any opening in a dwelling (window, door vent etc)
but preferably 0 feet.
2) Take your propane tank and place it next to the
generator making sure it is secured from tipping over
and close enough for the hose/regulator to reach with a
slight slack in the hose (not pulling on fittings). A milk
crate is ideal for 20 and 30lb tanks, but taller tanks will
need additional securing.
3) Close the valve on the propane tank then attach the
regulator with integral hose onto the tank. Connection
should be snug but do not tighten with a wrench.
4) Attach the other end of hose with the female quick-
disconnect onto the male quick-disconnect found on top
of generator. To do this, fully pull back on the safety
shroud of the female quick-disconnect to expose the
ring of bearings, insert fully over male fitting on
generator, then release the shroud to lock in place. See
“Safety Information” section of this supplement for more
details.
How to set the generator’s fuel selector switch
Your generator has a simple 3 position rocker switch located on
the top of the generator Always turn off the generator before
changing fuel selection! Note Natural gas is selected in
