RECOMMENDED FUEL
For the gasoline-powered units: Use clean, fresh
UNLEADED gasoline with a minimum octane rating of
87. Leaded REGULAR grade gasoline is an accept­
able substitute.
■ FOR GASEOUS FUEL-POWERED UNITS
Use clean, fresh commercial propane gas. The
optional LP gas system was designed for a VAPOR
WITHDRAWAL type system.
