The Gaseous Fuel System; Assembly/Installation - Briggs & Stratton 040248A Operator's Manual

The Gaseous Fuel System

The generator unit has been factory set to run on liquefied
petroleum gas.
WARNING Propane is extremely flammable and
explosive, which could cause burns, fire or
explosion resulting in death, serious injury
and/or property damage.
• LP gas is heavier than air and will settle in low areas.
• The slightest spark could ignite these fuels and cause
an explosion.
• DO NOT light a cigarette or smoke.
The generator engine is fitted with a fuel mixer system that
meets the specifications of the California Air Resources
Board for "tamper-proof" dual fuel systems.
• Use clean, dry fuel, free of moisture or any
particulate material. Using fuels outside the following
recommended values may cause performance
problems:
• Commercial grade HD5 LPG is recommended -
minimum fuel energy of 2500 BTU's/ft3 with maximum
propylene content of 5% and butane and heavier gas
content of 2.5% and minimum propane content of
90%.
• See Specifications for required fuel supply pressure.
