We got a propane heater the other day. The installation instructions call
for a "ground union" between the incoming on/off valve and the heater
connection. What's a "ground union" and what happens if I don't use one?

I might be totally wrong with this but I believe a ground union is a
connector that is grounded to allow static electricity to dischage
safely. I believe this is only used on fixed natural gas or the big
propane tanks.

If you Google "ground union" propane there are a bunch of pdf
files explaining what they are .

Like all gas things I assume if something goes wrong you get a fire and
massive explosion

That should read "ground joint union".

Look closely at a black iron (malleable) pipe union
and you'll see an embedded ring of copper or brass
which is carefully ground and polished to make
a leak-tight seal between the union halves.

Thanks to both of you. And you're correct, it is "Ground Joint Union".
