Gas log valve leak.

I converted my gas log from LP to NG. I replaced the orifices and reinstalled the valve and burner myself. I asked the HVAC guys to check the fittings for leaks and to light the pilot for me. They said everything checked out. I added the sand, embers and lavarock but now see a flame coming from the fitting for the tube that goes from the valve to the burner. It's obviously after the valve so it's not like it can fill the room with gas or anything but is this a problem? TIA

It sure sounds like a problem. There shouldn't be any flame near the valve.

That sounds like what happens to my gas grill when a spider builds a web - look for an obstruction. Maybe the burners are clogged.

PJMAX, The flame is outside the shroud that covers the valve. Still a problem?

Yes..... any leak is bad news. If you know a line is leaking..... it needs to be repaired.

Fixed

I put a couple of wrenches on the fitting and got another 1/8 turn or so on it and the leak went away.

There may not have been any thread sealing compound used.

I was lead to believe that no sealant was needed on tapered threads. So I didn't use any.

Yes.... tapered threaded gas lines need to be sealed.
A flare fitting wouldn't need sealant.
