This one more, and then I promise to quit picking on IH's service manual.

Flash point of PG is 99 - 103 C.

Ignition temperature of PG is 370 - 420 C.

Flash point of EG is 101 C.

I can't find ignition point of EG.

If I knew how to make degree symbols that would stay that way when I send
mail, I would. But I don't, so I won't, I guess.

This has all been very interesting to me, Colin, and I thank you for your
time and effort.
