Default I suspect "cabin fever" is to blame

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.


Those are the instructions on how to resolve a particular problem, not
the directions for S.O.P.


Do what you want.
