I have this old home made jet burner given to me with a shut off valve used to adjust the flame.
If I crank my regulator up past 12 psi and start to open up the valve on the burner, the regulator shuts down and goes to 0, leaving me a weak yellow flame.

What is the deal? Is there a shutoff in the regulator if the flow gets too high?
I was on a new bottle as well. What are guys running jet burners with and at what pressures are they running them?

The hole for the flame on homemade burner may not be big enough to allow that much pressure.

Were you given the regulator with the burner?

You also could have some trash (rust, dirt dauber dirt) in the line.

I was just given the burner. At 10 psi it puts out pretty flame but its not enough to get things back to a boil quickly when dumping the seafood in.

It just seems like there is something in the regulator that limits the flow on the regulator. It is the regulator that shuts down when i start to really open the valve on the burner itself.
I ended up only being able to open the burner valve up about 25% of the way and then open the regulator to 10psi. If I turned the reg up to 15% the regulator would shut down.

Dump the regulator, get a needle valve.

the part that screws into the tank has a safety valve depending on what color it is. you can upsize that or drill it out to disable it. i did the latter and have had no issues. red, black, green.... all rated for different pressures.

quote:

Different colors for the Type 1 Propane connectors are based on the spring tension and flow rate. The light green connectors are rated for 200,000 Btu per hour. The black are rated for 70,000-100,000 Btu per hour. The dark green are rated for 450,000-500,000 Btu per hour. The Red connector is the strongest spring and is often used for high pressure adapters and T-fittings.

Thanks poochie. I think this is the issue. When i buy the regulator i need to pay attention to the BTU rating. I didn't realize flow rates were limited for diff regulators even with the higher 30 psi regulators.

It’s the plastic part that screws on that you need to look at. But yes, I almost gave up before I researched and figured it out because it would cut off all the time when I tried to turn it up even just a little.

Good luck.

This is what I did too. Was sick of fooling with regulators and haven't had a problem since.

Thanks Reb and Leastbay.
Is it just as safe to run a needle valve? Are these available as a propane accessory?

It's just as safe as the regulator. You're only dealing with 150-160psi coming out of a standard 20lb propane tank. King Cooker sells a little brass needle valve for their burners.
