TIPS TO POWERING GENERATOR WITH NATURAL GAS
WARNING: Before installing fuel line consult with your local natural gas supplier to check codes and
regulations in your area.
Local codes will mandate
routing of gaseous fuel line piping around gardens and other landscaping to
correct
prevent any damage.
The information in this instruction is offered to assist you in providing the proper Natural Gas (NG) fuel
supply for your engine. This information is only provided to advise you of the engine requirements and
the decisions you must make. In no case should this information be interpreted to conflict with any local, state or national
code. If in doubt, always follow local codes.
WARNING: All fuel lines must be installed by a local qualified natural gas professional.
The fuel source should be as close as possible to the outdoor operating location. This will reduce the
installation cost of fuel runs. Connect the fuel supply line to the inlet on the generator using a locally approved flexible fuel
line.
The pressure supplied to the generator must be 4 TO 6 OUNCES or 7 to 11 INCHES W.C. (water column). The primary
regulator at the fuel supply must be capable of delivering the proper volume of fuel at this pressure. Again it is always best
to have local natural gas professional advise this information.
Fuel Consumptions (Fuel Load)
Natural Gas 160 cu. ft./hr 160,000 BTU/HR
Have your local fuel supplier install a protected fuel connection at the outside operating location. They should also install a
lockable fuel shut off valve at the connection point. An approved flexible fuel line must be installed between the engine
generator set and the supply line.
WARNING: The Natural Gas fuel supply line must always be shut off when the engine is not running.
Failure to do so may allow fuel to leak at the unit.
Do not use galvanized pipe in the fuel line runs. The galvanized coating will become eroded and flake off, causing
possible obstruction or damage to
the regulator or fuel valve. The obstruction could cause an inoperative engine or an explosive fuel leak.
WARNING: Be sure to always turn off the natural gas full supply to home before installation.
Note: All pipe sizing, construction and layout must comply with Natural Fire Protection Association
NFPA 54 for natural gas applications. Once the generator is installed, verify that the fuel pressure NEVER drops more
than one (1) inch water column from no load to full load from the starting pressure for either fuel type, and remains within
the limits of the stated specifications.
Size of pipe required for generators operating on natural gas. All pipe sizing is based on 1/2" WC pressure drop at 11" WC
setting. For pressure less than 11" WC (6 oz.) consult the gas company for proper line sizing for your flow rate.
WARNING: Do Not Run Natural Gas Line Over 200 feet to run generator
