3. Step-By-Step Outline of Installation 4-2010

See the Generator Set Specifications Table for fuel specifications, such as BTU. To

determine the required meter capacity, generator set consumption must be added to the gas

consumed for heating, cooking, clothes drying, etc.

· A typical installation might require a 400,000 BTU meter.

Consideration should also be given to utilizing high pressure gas supply (2 psi) if available. This

will reduce the required size, and therefore cost, of gas piping, especially if the location of the

generator set requires a long supply line.

NOTE: An older site might require upgrading and repair of the gas supply system,

which should be scheduled to minimize power and gas supply interruptions.

3.7.3.2 Natural Gas Supply Line Size

See the Generator Set Specifications Table for fuel specifications (such as BTU/hr).

The Natural Gas meter may not be adequate if the meter serves other gas appliances, such as

· Furnace

· Water heater

· Stove

To correctly size the fuel pipe, you must also take other loads operated from the fuel supply line

into consideration, such as:

· Space heating equipment

· Water heating equipment

Use the total load requirement of the fuel supply line to determine the size of the fuel supply

pipe. Use the Natural Gas Pipe Capacity - Cubic Feet of Gas Per Hour table to determine the

correct pipe size.

NOTE: Typically, 1 ft

/hr = 1000 BTU/hr. When the fuel delivery value falls between

two columns, use the larger value.
