Big Yellow Flames Under Burner

[MrSmith99]

I've got a Regency P36 fireplace that started to sound like rushing water (or gas) whenever we turned it on.
So, being a completely unqualified dummy I decided to take a look at the controls behind the bottom panel. As part of this process I wiggled the L-shaped wire thing that I think is the aeration control.
Now if I turn on the fireplace it has big yellow flames coming from beneath the burner. I've got a repairman coming next week, and I won't touch it before then. But I'm just wondering what I did.

Sounds to me like you're burning LP. You most likely have an alignment problem with the burner
orifice & the burner tube & you exacerbated the situation.
The wire you "wiggled' IS the Air Shutter & it should be WIDE OPEN (or nearly so) for burning LP.
You may have inadvertently closed it completely. The pressure of the LP & the fact that it is heavier
than air (& "puddles") is causing the ignition of the gas BEFORE it can get to the burner ports.

It's actually natural gas, but I do think I must have moved something related to air intake.
Thanks for your reply.

i'm not familiar with your model, but a lot of new burners (ember bed refractory type) have been leaking out the bottom of the pan.
hopefully your technitioan knows his stuff.

on ng you likely need air shutter 1/2 or more closed....

Thanks for your reply. I'll report back when I have the problem solved in case it happens to other folks.
