Elevation of ignition source

Also, this doesn't apply just to fuel fired appliances. Anything that sparks is a source of ignition: contactors, motors, ect. can also ignite gasoline fumes. Those items would also need to be elevated 18".

would you require receptacles to be 18+" above the floor?

Sorry, no. I should have said anything within the appliance that can spark. The code section is specific to appliances only, so this section does not include outlets. (BTW, I should qualify this with the fact that I only cover mechanical inspections. Inspectors in our jurisdiction are trade specific.)
 
Here's one I have heard a couple of times - "Does just the ignition source or the whole appliance need to be elevated 18 inches?"
 
The code section just says "source of ignition" so I take that to mean only whatever can ignite fumes. The bottom of the cabinet housing could be below 18" as long as any motors and contacts are up 18".
