increases back pressure. It may be necessary to increase the
exhaust pipe diameter in some applications.
The exhaust pipe is very hot. When passing through the
structure it is critical that a thimble or other appropriate
technique is used to dissipate the heat and prevent the
structure from catching on fire.
It is preferable to exhaust out the side of the enclosures.
Slope the pipe slightly downward away from the engine
to cause any water in the exhaust to run away from the
engine. Do not exhaust near intake. Once outside the
enclosure a rain cap or other technique must be used to
keep water out of the exhaust. In mobile applications make
sure the rain flap faces to the rear of the vehicle so that it is
not blown open during transportation.
The generator ships with a critical grade muffler that should
be installed to decrease noise. It can be mounted either
internally or externally to the enclosure. The muffler cannot
increase back pressure to more than 0.725 psi.
FUEL INSTALLATION
The fuel supply should be as close as possible to the
engine. This will reduce the installation cost of fuel runs.
The information in this manual is offered to assist you in
providing the proper fuel for your engine. However, this
information is only provided to inform you of the engine’s
requirements and assist in making you aware of the
decisions you must make. In no case should the instructions
and information provided be interpreted to conflict with
any local, state or national codes. If in doubt, always consult
your local fire marshal, gas supplier or building inspector.
WARNING: FIRE HAZARD
All fuel runs should be installed by a licensed fuel
supplier.
In no case should the instructions or information provided
be interpreted to conflict with any local, state, or national
codes. If in doubt, always consult your local fire marshal or
fuel supplier.
INSTALLING THE FUEL LINE
WARNING: FIRE DANGER
Connecting rigid fuel line (i.e. steel or copper line)
directly to the inlet fuel filter or fuel pump may cause
the fuel line to crack during operation creating a serious
fire hazard.
The fuel supply should be as close to the engine as
possible. This will reduce the installation cost of fuel runs
and minimize line losses. The diesel fuel supply should be
no more than 3 feet below the fuel inlet on the pump. If
your fuel supply is lower than three feet you may have to
install an additional lift pump to bring the fuel up to the
mechanical fuel pump on the engine.

Engine generator sets are properly adjusted before they
leave the factory. Connecting a fuel supply with adequate
supply volume is critical to reliable operation. Diesel units
with optional base mounted fuel tanks are pre-plumbed to
the mechanical fuel pump on the engine.
Open skid mounted diesel units are often supplied with
capped inlet and return lines. The use of a sustainable
customer supplied flexible fuel line is essential between
the engine and fuel supply to provide a vibration break
between your fuel supply and the engine.
LUBRICATION & COOLANT
Before starting the engine, check the oil level in the
crankcase. If it is low, refill to the full mark with the proper
weight/grade of oil. Failure to use the proper oil and keep
the crankcase properly filled will cause excessive engine
wear and shorten its useful life.
See LUBRICATION section under STARTING PROCEDURE
for oil specifications and recommended oil information.
WARNING: PERSONAL INJURY
Hot coolant and steam can cause serious injury or
death. Allow the engine to cool. Loosen the radiator
cap to release pressure before fully removing the cap.
Before starting the engine, Check the coolant level in the
radiator. If it is low, refill as specified in the engine
manufacturer’s maintenance instructions. The radiator
should be filled to about 1 inch below the filler neck.
INSTALLING THE BATTERY
CAUTION
In the following battery installation procedure, check to
be sure the DSE 7310 MKII is in the “stop” position. This
should be your last step before initial start-up.
A customer supplied Group 24 CCA battery is required to
complete the installation. Installation of the highest CCA
rated battery, within the correct BCI group, will increase
cold weather starting performance.
