Thanks to you guys, I finally got both fireplaces to light for Christmas!

PROBLEM 1:
The problem with one was I had not known the procedure (see below).

PROBLEM 2:
The problem with the other is that the gas is shooting out too fast & the
sparks are flying in the wrong places so it won't easily light on its own..

Here is the procedure that works on the good fireplace:

1. Open the keyed gas valve about one full turn CCW (master switch).http://imageshack.us/a/img835/4285/l...fireplace1.jpg

2. Turn the large gas dial to the central position (pilot position).http://imageshack.us/a/img833/561/li...fireplace2.jpg

3. Push the large gas dial in for about 10 seconds (pilot flow).http://imageshack.us/a/img59/7943/li...fireplace3.jpg

4. Push the small piezo-electric lighter a few times (light pilot).http://imageshack.us/a/img59/7384/li...fireplace4.jpg

5. Slowly release pressure on the large dial (pilot should stay lit).http://imageshack.us/a/img40/8479/li...fireplace5.jpg

6. Turn large dial 1 quarter turn CCW (the gas flow will audibly hiss).http://imageshack.us/a/img21/3803/li...fireplace6.jpg

7. Whoosh. The entire fireplace should light up in flame.http://imageshack.us/a/img844/904/li...fireplace0.jpg

there may be a bad regulator on the one that appears to have too much
gas........

i had a regulator failure on my gas grill that acted like yours.

for safetys sake get it checked
