Is there an expiration date on propane?

The newer regulator must have the right pressure rating to handle that large burner. How old are the rubber hoses? They can form a bubble inside that blocks the flow.

A good place to find parts for propane equipment it at a recreational vehicle supply store. Places like Home Depot have a limited selection.

Most commonly used on the propane gas grills with the new Type 1 System.

I am thinking that as a safety precaution the new regulator may not be adjustable. Mine is I just unscrew a cap on the top.

As for flow to the burner. If it hasn't been used for a long time it may be partially plugged. I cleaned out the jet (orifice) on mine one year only to find out that there was a spider web further up the line.

There should also be a combustion air plate that will turn to adjust the air/gas mixture. You want a nice blue flame with little or no yellow.

Getting enough flow out of one of the new regulators will probably not be sufficient for two burners and the big one.

Turn the main tank valve on slowly. It used to have a tendency to put the regulator in the wide open position if the main valve was opened quickly. The new regulator may have a built in safety to avoid this. That could explain low and erratic pressure.

When shutting off the newer equipment shut of the main gas valve first. Don't shut off the gas flow vales to the burners first. It can cause the above problem.

There is also a vent hole to the pressure regulator diaphragm that must not be plugged.

None of the regulator is adjustable, in fact I have not seen an adjustable regulator on the shelf in ALL the store. Actually I don't think the regulators are defective. I just came back from a place far away that is specialized in propane burners, here is what I got.

1) My burner is so big that it need the red color regulator to work.
2) The ones I bought from Home Depot and Lowes are all not for this big burner. The burner is so big that it does not create big enough back pressure to push the check valve open.
3) The one I said worked is a red one, therefore it works. I have to go buy another red one back for the other burner.

I still yet to test out the new one, so I post back later.

Please don't be rude, you did not ask very clearly until this morning when we cross posted. If you don't want to answer, let somebody else answer. This is absolutely uncalled for even though you are a contributor or whatever. One rude post is enough.

I asked you what color the regulators were (very clearly) in my very first post in this thread (#12). All of my questions have been very explicit, and you have ignored most of them. I had to try to troubleshoot by inference and waiting for you to accidentally post an important piece of information. Although I didn't explicitly tell you that your issue was in the order you opened the valves, I did mention that it is indeed a problem with the new tanks before the "cross post[ing]" today (my Dec 15th post).

If you had ever answered my questions, I could have told you the issues that followed from each. There was a specific reason for each question, a following list of issues, and simple tests/fixes for each. It was your avoidance that kept any of that from happening.

I'm surprised I kept posting, much less was simply "rude."

edward- There are adjustable and non-adjustable regulators.

The OP has not been forthcoming and has gotten rude. Thread closed.
