Propane has a much longer shelf life, and most facilities do not "test run" their generator sets weekly (or maybe ever). Also it doesn't smoke like a deisel and requires less maintenance. Mark at aero

The primary supply is the public utility and the back-up is to come from an on-site generator. The builder is proposing to use a propane-fired generator. I looked in NFPA 20 and 110 and didn't see anything saying this was a no-no. Is there a problem with this arrangement? Todd G.
