The real question here should be "Do you know how to install the glo plug gasket?"

There is a right side up, and a wrong side! Note that the plug has an angled chamfer just above the threads. The washer/gasket also has angle built into the material (sort of like a little cup). The cupped portion should fit the chamfered  angle on the plug so that the gasket fits snug on the plug.

Most often installing it upside down wont cause a problem, but it is possible to get leakage here with a corresponding loss in compression.

Fear not Glen, you are not alone. But you may be the only one man enough to admit it!

And what does the % of nitro have to do with the type of use for the plug?
