Well, the new propane regulator finally arrived so it was finally time to hook up to my propane burner. Initially I was intending to use an old Acetylene regulator that I no longer needed but:
- The connector was designed for one of the gray tanks, not the commonplace propane tanks.
- I’ve read conflicting information on whether you can safely use Acetylene regulators on Propane and vice versa.
Given that I’d need to buy adapters, etc, I decided that it just wasn’t worth the risk since propane regulators can be cheap (though they can also be very expensive.)
However, I had bought the high-pressure hose first, back when I thought I could use the Acetylene regulator… so now I had to mate that up to a propane regulator
I’d read good things about people using generic “turkey fryer” regulators and ended up going that way. Since I already had the Bayou Classic hose, it seemed like a good idea to get the Bayou Classic propane regulator and it seemed relatively well regarded as opposed to some others. It can go from 0 to 30 psi which should be plenty of heat for what I’m trying to do. 20 psi should be sufficient from my reading, but 30 gives us a little extra headroom.
Now, in retrospect, I may have been better served by buying a burner kit but I was doing piece-meal. If I’d gotten the kit, I could probably reuse the pressure gauge without needing to spend an extra $10 in connectors and extra mess.
So, one trip to Home Depot later, and I have the appropriate adapters. A 3/8″ flare step-down to 1/4″ FIP, a 1/4″ MIP bushing that screws into it that steps down to a 1/8″ FIP… which connects to the burner! Remember… gas-grade teflon.
Ok, so I hooked it all up and gave it the initial firing. Things look pretty good, but I think I may need a little more in the way of air intake… even fully open I get tiny tongues of orange flame. To be expected?
But there’s a problem… the flame is combusting IN THE TUBE, basically right at the end of the air intake… about 2-3″ past the tip of the jet.
What to do? I’m pretty sure that the gas is supposed to combust post-flare. I haven’t tried to light it up without the flare connected yet.
