The manual is silent on how much you open the gas valve on the tank. I
opened it all the way and then shut it off when the "test" was finished.

You should always open the valve all the way on an LP tank. *They are
designed with a "back-seat", which seals the valve stem when openend.
If you partially open it, gas can leak from the stem.

Wow, I did not know that.. I never seat anything unless I need to.

TOTALLY WRONG!!!! *Crack the valve about 1/4 turn. *Same with all flammable
gas cylinders. *O2, Argon etc. that are high pressure and inert have back
seals. *You want to be able to turn the tank off quickly if there is a leak
or fire. *Take any welding class and you will learn about gas safety.
Propane is a lot safer than a lot of the flammable gas as it is a liquid
under pressure and therefore is at a lot lower pressure in the tank.
Acetylene is a higher pressure in the tank but is in solution in acetone (I
think that is the liquid) as acetylene will self ignite explosively at a
fairly low pressure.

From the Weber website:

Cart Based Models
* Close the LP tank valve
* Turn all burner control knobs to the OFF position
* Open the grill lid
* Turn the LP tank valve until it is completely open
* Wait several seconds
* Turn the front burner to the HI/Start position
* Press the igniter until the burner is lit.
* Turn remaining burners to High
* Close the lid.
* The grill should preheat to 500-550 degrees in 10-15 minutes

As you point out, LP is not the same as acetylene.

The Weber folks also add that when turning on the LP tank valve, one should do
so very slowly so the regulator doesn't get overwhelmed. And, the 'several
seconds' wait should be at least 30.

That's what they told me when I couldn't get my grill to do more than just
flutter for a while and then die. Their technique worked. Now, though, I just
leave the LP valve open all the time. Oh, and buy something to protect the gas
line from squirrels. They love that rubber. I've been using one of these for a
few years now. Haven't had any problems after going through two hoses.
