To assist in the proper installation of the propane tank, follow the guidelines
below.
Consult your tank and propane supplier for assistance in all aspects of
determining tank size, selection of components and installation
requirements.
Fit the propane tanks with a pressure reducing regulator before
connection to the generator set to prevent fuel system damage.
Locate the propane tanks and all other fuel system components at least
10 feet (3 meters) from any source of combustion (including the generator
set). The fuel supplier or local code may require a larger distance
between the tank and source of combustion.
Install the propane tanks according to all national and local codes and
standards, and as required by the fuel tank and fuel supplier.
Refer to the Fuel Line Selection appendix for propane figures and tables.
Propane Vapor Fuel Supply Line Size and Pressure
Fuel line size depends on the amount of fuel needed to run the generator set
at full load at the distance the fuel must be moved.
To correctly size the fuel pipe, you must also take other loads operated from
the fuel supply line into consideration, such as space heating and water
heating equipment.
Use the total fuel requirement of the generator set and other connected
appliances to determine the size of the fuel supply pipe. Use the tables and
charts in the Fuel Line Selection appendix to determine the correct pipe size.
See the Model Specifications section for fuel system specifications, including
fuel consumption and required fuel system pressure at the generator set.
See the Propane Fuel System section for a typical propane vapor installation.
See the Fuel Line Selection appendix for fuel capacity at given distances and
pipe size.
NOTICE
Make sure the fuel supply pressure at the inlet of the generator set fuel
regulator (at service port) matches the requirements in the Model
Specifications section.
