- Mounting Studs
- AC Power Output Wires
- Gasoline Pump and Inlet Hose
- EVAP Carbon Canister Hose
- LP Inlet Fitting
- Wire Harness for Remote Control
Some of the basic components of the generator are shown in Fig. 4 above. A pair of mounting studs 1 are positioned on each side of the generator for picking up and handling of the generator. The AC power output wires 2 are shown exiting the generator and should be routed through liquid-tight conduit to a transfer switch, junction box, or power center. The gasoline pump is located on the outside of the housing for easy servicing or replacement. The EVAP carbon canister hose 4 is used when drawing gasoline from specific types of gasoline tanks that require EVAP controls. The LP fitting 5 is also found at this corner of the generator alongside the wire harness 6, which connects to the remote control panel for remote controls of the generator.
FRONT CONTROL PANEL
The front control panel (shown above as 6 – Front Control Panel) for the 2800i model is located behind the maintenance access cover and has the following features. See Figure 5 for an illustration of the front control panel and its button layout.
- Push Button Start – Push and hold for 1 to 2 seconds to automatically start the engine and push again to stop.
- Status indicator lights.
- Low Oil LED – This light indicates a low oil level and will not allow the engine to start or run.
- Overload LED – This light indicates a general system electrical overload, temperature protection, output short circuit, or any other abnormal conditions.
- Output Ready – This light indicates the generator is ready to use.
- ON/OFF 24 Amp AC Output Circuit Breaker – Allows the generator to automatically disconnect when overloaded to protect the generator and the appliance(s). Be sure to place the circuit breaker into the ‘ON’ position once the generator has successfully started.
- Reset Button – If the generator is overloaded, the inverter will disconnect at the AC overload breaker. The engine will continue to run, but there will be no electrical output. Reduce the electrical loads, then push the reset button, and then turn the breaker back to ‘ON.’
- Gasoline Primer Button – Press and hold the primer button to actuate the gasoline pump to bring fuel from the fuel tank to the generator engine. This is typically only needed the first time the generator is operated or after returning the generator to operation after being disconnected from the RV.
LIFTING AND HANDLING GENERATOR
When lifting a generator without a mounting frame, the generator should only be lifted from either A) the bottom surface areas of the generator or B) all four (4) mounting studs located on opposing sides of the generator. See Figure 6 below. The generator should never be lifted by the housing. A solid surface, a pair of forks, or a pair of straps can be placed underneath the generator to properly lift from the bottom. Care should be taken to ensure that the generator is held horizontally during handling and is not tipped, which could spill oil. Care should also be taken to ensure that no fork or strap contacts the exhaust outlet on the bottom of the generator, as this contact during lifting/moving could bend or break connections in the muffler and exhaust system. Further care should be taken during handling to ensure that fuel/LP lines are not pinched or crushed.
When lifting a generator with a mounting frame, the generator can be lifted either by A) the frame or (B) from the bottom.
LOCATION, MOUNTING, AND VENTILATION
This generator is designed to be installed into or onto a vehicle and must be securely mounted to the vehicle. For safety reasons, to prevent unintended access to live parts, it must be installed within a compartment that can be locked or requires a tool in order to open the compartment. It has to be installed in an area safe from road debris and must be guarded in such a way that the vehicle cannot be damaged by heat or vapors. The generator has to have exhaust, fuel, and electrical all installed correctly to function safely. A proper location must include all of the following:
- Enough space based on the generator dimensions shown above.
- Enough space to connect and disconnect fuel lines, a remote control wiring harness, and AC power output lines.
- Enough space to access the front control panel for starting/stopping the generator and performing all periodic maintenance.
- Separation from any flammable vapors or liquids, including fuel tanks and batteries, to prevent the generator from igniting these substances.
- Access to the bottom of the generator for draining oil, removing spark arrestor on muffler, and installing exhaust.
- Ground clearance of at least 12 inches.
- Space below, above, and to the sides of the generator for adequate cooling airflow.
- Placed within a compartment that is either lockable or requires a tool to open.
WARNING
Supporting structure must be strong enough to hold and secure the generator.
Insufficient structure may cause damage to the vehicle or the generator may
become detached from the vehicle causing serious damage, injury, or death.
The generator weighs approximately 106 lbs (48 kg) and must be installed in a
location that can support the weight of the generator, as well as the motion
of the generator and the added forces of the generator when traveling (approx
+/-1G Force vertical and +/-3G Force horizontal).
Mounting of the generator will be dependent on the design of the structure,
but fasteners should not intrude into the generator more than required. If
installed near wheels, install guarding to protect the generator from debris.
HANGING FRAME INSTALLATIONS
When hanging the generator below the floor of the RV, use the hanging frame and mounting bolts to hang the generator from the RV floor above. This is the preferred method of mounting the generator as it allows maximum airflow beneath the generator and to the sides as well as easy access to install the exhaust as well as drain the oil. However, barriers to vapor and fire must be placed between the generator and the floor above. A 26GA fire barrier must be installed to protect the floor. If the floor is plywood, steel must be used to reinforce the mechanical support for the generator. Choose the mounting location so that the generator is not within the approach or departure angles of the vehicle and is above the axle line. If installed near wheels, install guarding to protect the generator from debris. For mounting bolts, use at least ⅜” bolts with washers and locking washers, with all parts either galvanized steel or stainless steel. See the dimensions of the hanging frame above to determine the locations for marking and drilling holes for the mounting bolts.
FLOOR MOUNT INSTALLATIONS
When mounting on the floor of a compartment, adequate ventilation for the
generator must be established or the generator will quickly overheat (the hot
cooling air exits the bottom of the generator, and if it has nowhere to go it
will be immediately recirculated into the generator’s cooling system on the
right-hand side). For this reason, it is not advisable to mount the generator
directly atop a floor, unless the installation includes removing a substantial
portion of the floor to ensure adequate cooling airflow (as depicted on page
13).
The generator must be installed in a vapor-tight 26GA or greater enclosure to
prevent both fire and vapors from getting into the vehicle. The entire
compartment (except the floor) must be lined with vapor and fire-resistive
materials. All seams and openings in the barriers for wiring, mounting screws,
etc must be sealed. Appropriate materials must be used (26 gauge steel or
equivalent). See NFPA 1192 for more information. If the floor is of
combustible material, such as wood, the compartment and door must be lined
with ¼ to ½ inch thick, 4 lb/ft3 density fiberglass thermal insulation with
aluminum foil facing at least 0.001 inch thick. Secure the insulation every 12
inches to the surfaces being protected by mechanical fasteners with washers at
least 1 inch in diameter.
Acoustic and/or thermal insulation may be used but must be self-extinguishing
at 200 degrees F and do not place these materials below the generator as they
can absorb fuel and oil and will keep the heat from the hot air coming out of
the bottom of the generator from escaping. All fuel and electrical lines must
be properly protected when routing so that they cannot be cut on raw metal.
Any and all openings must be sealed to prevent vapors from entering the
vehicle.
FLOOR MOUNTING WITH PROPER VENTILATION
As noted above, the generator must have adequate cooling air flow in order to
cool itself, especially when running in very hot ambient temperatures or when
running at the same time as a chassis engine. Ideally, the entire bottom of
the compartment is open to the road to ensure the maximum amount of fresh
cooling air is ingested into the generator and the hot air can be easily
exhausted out of the bottom (Note: This hot air is cooling air and is
different from the combustion exhaust that is piped out separately from the
muffler and is described further below). See the diagram below, which
illustrates the flow of cooling air into and out of the housing for the
generator, and note where the cold air enters and hot air exits, keeping these
flows separated from each other is critically important to prevent overheating
and increase the life of the generator.
Even if the entire bottom of the compartment is open to the road, it is still
critical to ensure adequate clearance at the top of the generator housing for
the cold air inlet, so there should be at least two (2) inches of space
(preferably more but when using the hanging method this is sometimes not
possible) between the cold air inlet at the top of the generator and the
surface immediately above. Further, even if the entire bottom of the
compartment is open to the road, it is still critical to ensure adequate
clearance for the cold air inlets that are positioned on the removable door of
the generator, as well as the air inlets on the right side housing of the
generator. These inlets are important, be sure to maintain at least two (2)
inches of space
(preferably more) between the cold air inlets on the door and the next
surface. Preferably, if the cold air inlets on the door are very close to the
interior surface of the compartment door, a vent should be installed within
the compartment door and adjacent to the cold air inlets on the door so that
outside cool air can be easily drawn into the cold air inlets on the front
door of the generator. This vent should preferably be between 20in2 and 40in2
in area.
When positioned within a closed compartment having a floor, the compartment
must be heavily vented with fresh air, so that large portions of the floor of
the compartment will need to be removed. As shown below, several areas will
need to be removed for both airflow purposes as well as access to the
carburetor gasoline drain.
Note the locations and dimensions (all shown in inches) of each of the
features above, as they will need to be removed from the floor of the
compartment.
-
Mark the location for the hot air vent and the exhaust pipe to pass through the substructure and remove this portion of the substructure.
-
Mark the location for the carburetor drain / gasoline overflow to pass through the substructure and remove this portion of the substructure.
-
Mark the location for the cold air vent for plenty of cold air to enter the compartment.
-
Remove these areas from the substructure.
Once these ventilation and oil drain portions are removed from the substructure, the location of the mounting bolts should be marked and drilled out of the substructure. The generator contains a set of two (2) female threaded holes along the front and rear edges of the generator for a total of four (4) mounting holes that accept M10x1.50 bolts. The location of these threaded holes are shown below with reference to the ventilation and oil drain portions removed above. -
Mark the locations of the female threaded holes across the front of the generator which receive bolts (Front Bolts #1-2)
-
Mark the locations of the female threaded holes across the rear of the generator which receive bolts (Rear Bolts #1-2)
-
Drill one half inch (/”) diameter holes at each location
Once the ventilation, oil drain, and mounting bolt portions of the floor/substructure have been removed, the generator can be bolted into place. Position the generator above the cutouts and mounting holes and ensure everything lines up before bolting the generator into place. If anything does not align properly, specifically the ventilation holes and access to the exhaust attachment at the muffler (ensure that there is plenty of room to install the exhaust to the muffler and attach an exhaust clamp), remove the generator and mark the additional substructure that needs to be removed. Once this is removed, replace the generator in its location and check to ensure the accuracy of all ventilation and mounting bolt locations. -
Place the generator atop the cutouts for the vents and the locations of the mounting bolt holes.
-
Install two (2) M10 bolts across the front of the generator (Front Bolts #1 – #2).
-
Install two (2) M10 bolts across the rear of the generator (Rear Bolts #1 – #2).
-
Ensure that each bolt is long enough to pass through the substrate and engage adequately with the female threaded holes in the generator.
-
Use flat washers as well as locking washers on each bolt for a secure connection.
In some applications, especially where rodents and animals are frequently attempting to enter the compartment, a screen/mesh/louver may be attached to cover the ventilation portions as well as the access to the oil drain. This is optional. Be sure that any covering used does not become clogged with dirt, dust, or debris. Be sure to check any coverings to ensure that airflow remains unimpeded and clean or replace any coverings that become restricted. Airflow to your generator is critical to its lifetime and performance.
EXHAUST
WARNING
EXHAUST GAS IS HOT AND DEADLY. Never inhale exhaust gas. Always route exhaust
pipes outside of the vehicle and terminate the tailpipe at the appropriate
location. Use only approved materials for the exhaust pipe and always use
proper clamps and hangers and ensure that there are no leaks. Never mount the
exhaust where it could be damaged or punctured.
WARNING
DO NOT MODIFY MUFFLER. Modification or alteration to the muffler will void the
US Forest Service approval of the muffler. A fire can be started when using a
generator without a proper spark arresting exhaust system. The person making
any modification or knowingly using a modified muffler is liable for any
warranty, injury, or damage caused by a modified muffler.
-
The generator exhaust can be routed in two different ways depending on the installation and application. As shown in the figure below, Option A will expel the hot exhaust gasses out of the side of the generator, while Option B will expel the hot gasses directly down out of the bottom of the generator.
-
Make sure there is no debris blocking the exhaust tailpipe. If the RV has been stored for the winter, remove the plug from the tailpipe. Look and listen for exhaust system leaks while operating the generator while it is running. Shut the generator down if an exhaust leak has been found and have it repaired before continued operation.
Look for openings or holes between the generator and the living compartment or vehicle cab, where exhaust gasses could enter or if the generator sounds louder than usual, indicating a hole in an exhaust tube that would allow gasses to enter. Have an experienced service technician permanently close any holes or other breaches. Replace dented or rusted exhaust components and make sure the tailpipe extends at least 1 inch beyond the perimeter of the RV. See NFPA 1192 (Section 6.4.3-6.4.6) for additional guidance on proper exhaust routing and support. -
Park the RV so the generator exhaust gasses can disperse away from the RV. Barriers such as walls, snow banks, high grasses and brush and other vehicles in close proximity can cause exhaust gasses to accumulate in and around the RV. Do not operate power ventilators or exhaust fans while the vehicle is standing with the generator running. The ventilator or fan can draw exhaust gasses into the vehicle.
When installing the exhaust system, use ridgid 18 gauge steel or greater with 1.25 inch OD (muffler outlet is st1.13 inch OD). While the directions below show separate pieces being connected to form the exhaust system, RVMP (and others) may offer exhaust kits with a single pipe already formed with a 90-degree bend. When replacing an old generator, if the previous exhaust was not rusted out or otherwise damaged, it can be re-used for the FLEX POWER generator.
- Route the exhaust using the straightest path possible directly to an acceptable sidewall of the RV. Note below how the exhaust pipe must not release any exhaust gasses beneath any openings in the periphery of the RV, so check the surroundings to ensure they can accept exhaust gasses before deciding on the final termination spot for the exhaust.
- Use only proper U-bolt exhaust clamps to connect the exhaust to the muffler outlet and any additional pipes. If necessary, connect 90 degree elbows or couplings with straight horizontal pipe to reach the nearest periphery of the vehicle that is acceptable for exhaust termination, using proper U-bolt exhaust clamps only.
- Connect a series of horizontal pipes to route the exhaust to the nearest periphery of the vehicle, using proper U-bolt exhaust clamps only. Ensure that the tailpipe extends beyond the body perimeter of the vehicle as specified below.
- Ensure that the tailpipe extends far enough away so that exhaust gas cannot be trapped beneath the vehicle, at least 1 inch beyond the perimeter of the vehicle. See the figure below for measuring the body perimeter of curved vehicles, as well as NFPA 1192 Section 6.4.3 for more details. “Line A” provides a line beyond which the exhaust termination opening must extend to satisfy the standard and this is determined by drawing a vertical line through the tangent point determined by “Line B.” Whereas “Line B” is determined by projecting a 45-degree angle from the horizontal plane created by the ground to where it is tangent to the vehicle wall surface.
- Ensure adequate road clearance so that the exhaust cannot be damaged by road bumps or deflation of tires. The road clearance for areas that are not found between the wheels of the vehicle can be measured by establishing a front and rear wheel departure line, which is a straight line from the front and rear tire-road interface to the front and rear bumper, respectively. See Figure below. All exhaust pipes should be placed as high above this line as possible.
- Install skid bars to provide an additional protected area for the exhaust pipe (if necessary).
- Ensure that no unsealed air passage into the vehicle is located within 6 inches of the exhaust pipe termination. This includes but is not limited to: 1) power cord hatches that have an air passage to the interior, 2) windows, 3) city water fill that has a communicable air passage, 4) storage compartment doors where the compartment is not sealed to the interior and 5) entry doors. However, unventilated compartment doors that are sealed with sealing materials (gaskets, foam tape, or equivalent) are not considered openings and therefore are exempt from this requirement. See the figure below. “Door A” requires the entire compartment to be sealed vapor-tight to the interior of the vehicle. “Door B” does not require the compartment to be sealed vapor-tight to the interior of the vehicle.
- The exhaust may terminate beneath a slide-out only if the slide-out is at least 36 inches vertically away from the exhaust, measured from the exhaust to the bottom of the slide-out. However, the exhaust termination cannot be placed below a slide-out that is less than 36 inches vertically from the exhaust termination.
- Support the exhaust pipe at least every 3 feet with proper exhaust hangers and ensure a slight downward slope in the horizontal pipes (¼ inch for every 3 feet) to allow drainage out of the end of the exhaust pipe. Place an exhaust hanger as close to the exhaust pipe termination as possible.
- Do not route exhaust near fuel lines or other combustible materials.
- Do not leave exhaust termination upturned to collect moisture.
- Do not use a flexible exhaust pipe.
- Do not connect the generator exhaust to the exhaust for the vehicle or any other exhaust.
Exhaust Recirculation Test
It is recommended to check that the generator is not recirculating the exhaust
gasses or the hot air off the engine after installation. After the generator
has been completely installed, in an outdoor space without wind and relative
temperature, run the generator for an hour with all of the doors and cabinets
shut and the exhaust vented as designed. Place a medium load demand (approx.
10 Amp) during this time. Using a thermocouple, measure the air at the inlet
fan on the side of the generator. The temperature should level out within the
hour. If the temperature does not level out, but instead continues to increase
and increase, check to see if the exhaust is correctly vented away or if there
is enough inlet air being brought in.
PROPANE CONNECTIONS
WARNING
Propane gas (LP gas) can cause asphyxiation and is highly flammable and
combustible. Propane gas can cause injury, damage, or death if improperly
handled. Never handle around fire, sparks, or any other ignition source. Never
route any propane lines near electrical wiring or heat-producing components.
Always keep fire prevention equipment on hand when working with propane. Be
aware of and trained on the various dangers of working with propane gas. The
correct procedure is laid out in NFPA 58, Sect. 1.6. It is recommended that
all work on the propane system is done by experienced and qualified personnel.
WARNING
Over-pressurization of the propane system can cause damage to the equipment
and will hinder the ability to seal the system. This can cause leaks and
potentially asphyxiation, fire, damage, and death. If the fuel system is
improperly sized, flameout can be caused, leading to leaking of propane and
fire, asphyxiation, damage, and death. The system must be properly designed to
prevent this. Improper testing of the fuel system can lead to ignition of
propane, causing fire, damage, and death. A person properly trained to adjust
the system is required if the propane system needs any modification.
- Gasoline pump and supply hose
- EVAP carbon canister hose
- LP inlet fitting
The propane system should be plumbed in seamless steel piping with flared ends. Use the following sizes according to length for determining proper pipe size.
PIPE SIZE | MAX LENGTH |
---|---|
⅜” ID | 3 FT |
½” ID | 15 FT |
Flexible hoses should only be used at the generator and at the propane tank to
make connections. Use only low-permeation fuel hoses rated for propane. Attach
the flexible hose to the generator propane inlet using a ½” female 45-degree
flare fitting (generator attachment is a male ½” 45-degree flare fitting).
Do not combine or split the generator fuel line with a propane fuel supply
line that is already supplying another appliance, as the generator will starve
out the rest of the system, due to its large draw with large demands. The
propane system needs to be designed to properly supply the appliances and
generator under normal operations and conditions, which may demand split
systems.
The generator demands a gas pressure range of 9-13 in (229-330mm) water
column. Pressure must not exceed this range or could cause damage. Use only
with tanks having a manual shutoff valve as well as a two stage pressure
regulator. The generator requires a low-pressure regulator, do not use a high-
pressure regulator.
The propane system must be installed using the Standard for Storage and
Handling of Liquified Petroleum Gases (NFPA No. 58) as a governing document.
The system should be thoroughly checked for leaks after installation and only
with approved methods such as soapy water. Every part of the fuel system and
all connections should be tested in this manner.
Although properly set up when installed, the propane system may need to be
adjusted due to elevation, temperature, and fuel sources.
GASOLINE FUEL CONNECTIONS
WARNING
Gasoline vapors can cause asphyxiation or death. Gasoline is highly flammable
and combustible and can cause injury, damage, or death if improperly handled.
Never handle around fire, sparks, or any other ignition source. Never route
any gasoline lines near electrical wiring or heat-producing equipment. Always
keep fire prevention equipment on hand when working with gasoline. Be aware of
and trained on the various dangers of working with gasoline. It is recommended
that all work on the gasoline system is done by experienced and qualified
personnel.
WARNING
Gasoline system over-pressurization can cause damage to both equipment and the
ability to seal the system. This can cause leaks, fire, damage, and death. Do
not connect the generator gas line to vehicle gas lines, as the system can
starve or flood the generator, potentially causing damage. If connecting to a
vehicle gasoline tank, use a separate drawtube. Connect according to vehicle
recommendations and connect at a level higher than the vehicle so as to not
run the vehicle out of fuel during operations. Proper fuel line pressure
should not exceed 1.5 PSI under any circumstances.
This generator is intended for RVs that already have fuel lines run to the
compartment for the generator. RVMP recommends that only trained and
experienced installers extend or install any type of fuel line. For fuel
lines, the gasoline system should only use ¼ inch ID stainless or low carbon
steel tubing (AISI 1008-1010) with double flared fittings to make any long
connections. The tubing must allow 150 PSI operating pressure and have
corrosion resistance equal to or better than hot-dipped zinc galvanized steel.
When connecting to a gasoline tank, connect from the top, to prevent siphoning
if a line is damaged. Maximum fuel pump lift is 36 inches, therefore only
install with less than 36 inches of lift from the lowest fuel level to the
generator to ensure adequate pressure to draw fuel. Run fuel lines away from
rough edges, heated areas, and electrical lines/connections and properly
secure to prevent vibration damage and pinching of the lines.
Connect the fuel system to the generator with a ¼ inch barb fitting. When
connecting hoses, use only lubricants without soap, such as WD40. Soap can be
caught in the carburetor of the engine if used and possibly cause in-
operation. For connections at the generator or the fuel tank, use ¼ inch ID
(SAE 30-R7) low permeation flexible hose with stainless steel ear clamps only.
The hoses in the generator meet US and California standards for gasoline
evaporative emissions in that they are low permeation. If making a connection
to the generator with fuel hoses, they need to meet the standards for low
permeation and evaporative emissions required in California.
GASOLINE VAPOR CONNECTIONS
When using the generator with a gasoline system, an evaporative system is
required to meet some local/regional regulations, including CARB and EPA. The
generator has been tested and configured to comply with the evaporative system
configuration as provided at the sale. Due to the specific nature of this
configuration and the customer’s install, it is recommended to contact the
proper governing bodies for the specific regulations of this type of
installation. It is the responsibility of the RV equipment manufacturer OEM to
complete the installation of the evaporative fuel system exactly as specified
in the CARB and EPA certification for the RVMP generator products. Use only
with approved carbon canisters, contact RVMP support at
855-427-7978 for additional information
This generator is intended for RVs that already have evaporative lines run to
the compartment for the generator, connecting to a carbon canister already
installed by the RV equipment manufacturer OEM. RVMP recommends that only
trained and experienced installers extend or install any type of evaporative
line. For evaporative lines, the system should only use 5/16 inch ID stainless
or low carbon steel tubing (AISI 1008-1010) with double flared fittings to
make any long connections. The tubing must allow 150 PSI operating pressure
and have corrosion resistance equal to or better than hot-dipped zinc
galvanized steel.
Connect the evaporative system to the generator with a 5/16 inch barb fitting.
When connecting hoses, use only lubricants without soap, such as WD40. Soap
can be caught in the carburetor of the engine if used and possibly cause in-

ELECTRICAL CONNECTIONS
WARNING
ELECTROCUTION DANGER! A generator has high voltages that can cause severe
shock or death. Be aware of what is being touched inside a generator, remove
anything that can cause accidental touching, and always work on an insulated
table and floor to reduce the risk of electrical shock when working on the
generator.
- Incorrect wiring can lead to damage, fire, injury, or death. Be aware of connections inside and outside the generator. Do not make connections to the battery until ready to start the generator, to prevent accidental starting or shorting. Incorrect wiring in battery storage can lead to damage, fire, injury, or death. Venting of battery area is necessary to vent off explosive gasses.
- Never connect the generator to a vehicle that can also receive shore power (utility) without a proper transfer switch or power switching / management system. Backfeed to shore power (utility) can cause electrocution or damage to equipment. Any vehicle with provisions for connecting to shore power must have an approved device to keep the generator and utility from being interconnected.
All electrical work should be performed by an experienced and qualified electrician. Be sure that all electrical work conforms to the National Electrical Code (NEC) with properly sized conductors, connections, and junction boxes.
AC Power Output for 2800i Models
A set of three (3) AC conductors exit the bottom side of the generator, with
the colors and polarity detailed in the chart below.
Wire Color | Polarity |
---|---|
Black (10 AWG) | Hot (+) |
White (10 AWG) | Neutral (-) |
Green (8 AWG) | Ground |
These AC conductors are connected through a 24 Amp breaker to protect the generator. For the initial start up of a new generator, or when starting a generator for the first time in 60 days, be sure to have the 24 Amp breaker set to OFF. Once the generator has started and the engine warmed up (approx. 5-10 minutes of run time), the breaker can be switched to ON which will send the AC power out from the generator. This can help extend the life of the generator. When a generator is brand new, it is best to run the generator with no load for 30 minutes before loading the generator with any appliances.
AC Output Power Connections
If the RV is not capable of accepting shore power, connect these AC conductors
to an AC distribution panel which would contain a plurality of breakers for
distributing AC power to a plurality of AC appliances on the RV.
Alternatively, if the RV is capable of accepting shore power, these AC
conductors must connect to a transfer switch capable of switching between
shore power and generator power. A transfer switch must be used with any RV
that accepts shore power or backfeeding into the generator can occur and will
void any warranty and severely damage the generator.
The AC conductors are approximately 120 inches long. If these conductors are
not long enough to reach the transfer switch or AC distribution panel, then
the AC conductors should be routed to a proper junction box where longer
conductors can connect to the existing generator conductors and complete the
run to the transfer switch or AC distribution panel.
BATTERY CONNECTIONS AND GROUNDING
WARNING
Do not connect the generator to the battery until installation is complete.
Never route battery electrical lines with or near fuel lines. Routing battery
cables with fuel lines can ignite vapors or fuel and can cause fire and
serious personal injury or death.
- Negative Battery Terminal
- Positive Battery Terminal
The generator requires 12V DC power to start and a minimum of 450 CCA is
necessary to perform starting at 0 degrees Fahrenheit. Battery(s) must be
installed in a proper battery compartment that is vented properly. See
ANSI/RVIA LV Section 2-3 for battery compartment venting and proper
installation.
Using a single continuous run of positive and negative conductors from the
battery to the generator is highly recommended. Size the battery conductors
based on the chart provided below. The conductors must be properly sized or
the wires could heat up, causing an electrical short or fire. Battery wires
should be routed away from any fuel lines. If there is any break in the
battery conductors, it must be kept free from corrosion and weather.
Total Cable Length (Distance from battery to generator and
back to battery)| Cable Size (AWG)
---|---
0 to 45 Feet (0 to 13.7 meters)| 6
46 to 60 Feet (14 to 18.3 meters)| 6
61 to 80 Feet (18.6 to 24.4 meters)| 4
Use proper battery terminal eyelets to connect a positive conduction line and a negative conduction line to the battery, size these conductors based on the table above. Depending on location, precise install situation, and corresponding NEC, it may be necessary to route a ground conductor from the negative terminal of the battery to the vehicle frame and from the generator negative terminal to the frame (preferably using a minimum of #8 AWG). Be sure to check all connections with a licensed electrician before starting the generator.
ELECTRICAL WIRING FOR REMOTE CONTROL FUNCTIONS
The generator is provided with an electrical connector that is designed to
connect with the pre-wiring in most RVs for controlling the generator with a
remote control. Many include a remote control panel that allows control of
various functions of the generator from inside the RV. In many cases, this
connector will easily connect to the corresponding connector on the remote
control panel, but if not, below is a chart of the corresponding pin functions
for each pin on the connector.
Location | Color | Function | Uses | Connection to make function |
---|---|---|---|---|
A | Black | Ground | Ground | N/A |
B | Blue | Start/Stop | Starting and Stopping Generator | D |
C | Red | Prime | Prime Gasoline | D |
D | Pink | 12VDC | 12VDC – Light, Timer | D |
E | White | Reset + | Reset Overload Condition | F |
F | Gray | Reset – | Reset Overload Condition | E |
G | N/A | N/A | Do not use | N/A |
H | N/A | N/A | Do not use | N/A |
Functional Descriptions:
Prime Gasoline – Used to prime the gasoline fuel pump to fill carb before
starting. After installation and before starting for the first time, prime the
generator; after the first run, the generator has auto prime when the normal
start sequence is enacted.
- Start/Stop – Works just like the Start/Stop switch on the generator. Used to trigger remote/auto start functions.
- Reset – This resets the generator after an overload condition is detected and the generator shuts down for safety.

ENGINE OIL RECOMMENDATIONS
Use API (American Petroleum Institute) performance class SJ engine oil or
better. Also look for the SAE (Society of Automotive Engineers) viscosity
grade. Referring to Fig. 11 below, choose the viscosity grade appropriate for
the ambient temperatures expected until the next scheduled oil change. Single-
grade SAE 30 oil is preferable when temperatures are consistently above
freezing. Multi-grade oils are better when wide temperature variations are
expected.
NOTE: Maintenance schedule must be followed even when using synthetic
oils.
STARTING BATTERY
A minimum battery rating is 450 CCA (cold cranking amps) at 0 degrees
Fahrenheit for both gasoline and LP models. Ensure at least 12 volts for
starting batteries.
INITIAL START UP PROCEDURE
- Ensure that the generator is filled with the correct oil type.
- 12V DC Battery connection is secured to the generator.
- Switch AC breaker(s) on the generator control panel to OFF.
- Open the fuel connection and make sure the switch is on the correct type of fuel desired to burn in the generator.
- Prime gasoline system using priming button (if using gasoline).
- Press and hold the Start button for 2-4 seconds.
- If the generator does not start on the first attempt, it will automatically try 2 more starts before waiting for further input. Allow the generator to try a total of 3 starts before pressing the Start button again. It may take several attempts initially to remove air pockets and fully prime the lines with fuel to the carb.
- Once started, allow the generator to run for 30 minutes with no load to warm up.
- Switch breaker(s) on the generator control panel to ON.
- Turn on appliances in the RV to load the generator with approximately 50% of the max rated watts for the generator and allow the generator to run for another 30 minutes.
If everything is running correctly and outputting power, test for recirculation as stated in exhaust Section 6.0.
SPARK ARRESTOR MAINTENANCE
The Flex Power generators are fitted with a Spark Arrestor Muffler, these
mufflers have a maintenance cycle to ensure the operational functionality of
the spark arrestor. Spark arrestor style mufflers are designed to prevent
solid particles from exiting the exhaust. A spark arrester acts like an air
filter, removing all solid particles from the exhaust stream.
All internal combustion engines emit potentially dangerous sparks under normal
operating conditions. These sparks, or carbon particles are formed as a
product of combustion in the engine cylinder head and are constantly expelled
through the exhaust system during engine operation. For example, dry grasses
will ignite at about 400°F, making off highway vehicles a potential fire
hazard. This is why State (PRC 4442) and Federal law (CFR 261.52(j) require
that off highway vehicles must have a Forest Service approved spark arrester,
properly installed and maintained.
The Spark Arrestor should be inspected every 1,000 operating hours or three
times per season.
NOTE: Service in an area where there is no danger from flying sparks or
hot carbon particles.
- Stop the engine and allow exhaust system to cool.
- Remove clean-out plug with a wrench. If a crust has formed over the hole, break it loose with a screwdriver or similar tool.
- Start the engine and run it at a high idle to blow collected particles out the clean-out hole. If particles are slow to discharge, momentarily cover the end of the exhaust stack.
- Stop the engine and replace clean-out plug securely.
WARNING
A hot muffler can cause severe burns. Let the muffler cool down before
removing or installing the cleanout plugs.
