Consult Manual. Read and understand manual
completely before using product. Failure to
completely understand manual and product
could result in death or serious injury.
NOTE: The operation of this unit should only be
performed by an authorized operator who has been
properly trained by a GMP ASD. Contact your local GMP
ASD for assistance in training authorized operators.
Read the operating manual thoroughly and understand
all instructions before operating the equipment.
The unit should be installed, serviced, tested, adjusted,
and otherwise prepared for use by a GMP ASD. The
owner is responsible for ensuring the unit’s emission
control system meets all applicable state and local
regulations.
Well Site Approval
A well gas chromatography analysis must be performed
prior to installation of the unit. A copy of the test report
must be sent to, and pre-approved by, Generac Mobile
Products. If the unit is moved to a new location, a new
well test must be performed. For more information,
contact Generac Mobile Products Technical Service.
Natural Gas Connections
NOTE: The unit can operate on 5-50 psig or 40-300 psig
fuel supply pressure.
NOTE: Using the utility supply requires remove of main
pressure gauge and shut off of the 2 in. ball valve directly
upstream.
NOTE: Installer must verify that all fuel connections
comply with all building codes.
Follow the steps below:
1.
Apply pipe sealant to the NPT threads of the fitting
at the end of the fuel line.
NOTE: Do not apply pipe sealant to flared (flanged) end
of the fitting.
2.
Connect fuel line to the two inch inlet, located on
the right side of the unit’s frame.
3.
Verify all connections are sealed and no leaks are
present.
4.
Verify fuel supply pressure is adequate.
IMPORTANT NOTE: Properly size piping based on
site pressure.
Formula Example (English):
If a unit has a 160 hp engine 60 feet from the supply, the
engine needs 10,000 BTU/hr per hp to run efficiently. For
natural gas fuel, there are 1015 BTU/ft
3
.
160 hp x 10,000 BTU/Hr per hp =
1,600,000 BTU’s / per hour for proper operation
1,600,000 = 1576 cubic feet per hour
1,015
Formula Example (Metric):
If a unit has a 120 kWe output, the engine needs 3.4
times more fuel energy than electrical output to run
efficiently. For natural gas fuel, there are 47 MJ/kg (32
MJ/m
3
).
120 kWe x 3.4 = 408 kW = 408,000 W
408,000 W
