3.8.4.1 Recommended Fuel (Propane)

WARNING

Propane presents the hazard of fire or explosion that can cause severe personal injury

or death. Do not permit any flame, spark, arc-producing equipment, switch, pilot light,

cigarette or other ignition source near the fuel system. Keep an ABC type fire

extinguisher nearby.

Use clean, fresh HD-5 grade Propane or equivalent product consisting of at least 90% Propane.

NOTICE

Commercial Propane may contain more than 2.5% butane, which can result in poor fuel

vaporization and low tank pressure - resulting in poor engine staring in below 32 °F (O

°C) temperatures.

3.8.4.2 Propane Tank Size

First, some Propane tank facts to bear in mind when figuring the proper Propane tank size:

• Propane tanks are sized by the number of gallons of water they can hold, not the amount

of fuel they can hold.

• Propane tanks are generally filled to only 80% of their water capacity. Therefore, a 500 lb.

tank results in 400 lb. tank capacity.

• Low ambient temperatures affect the amount of fuel available from the Propane tank.

• Approximately 60% of the fuel (in gallons) filled in the tank can be effectively used.

Therefore, a 500 lb. tank results in 300 gallon capacity.

To assist in the proper selection of the Propane tank, follow the guidelines below.

• Propane tanks must be fitted with a pressure reducing regulator before connection to the

generator set to prevent fuel system damage.

• Propane tanks must be located at least 10 ft. (3048 mm) from any source of combustion

(including the generator set).
