Perhaps there maybe some confusion as to how the fireplace was shutdown.

I'm also thinking there is some confusion here as well.
I checked the instruction manual for my (Desa GA9050A-1 series) fireplace and it shows that the gas control knob should be able to be turned from 0 degrees to 180 degrees to let the gas in to light up the fireplace and that to turn the pilot light on you need to wait for any natural gas that is left to dissipate, then turn the knob 90 degrees, press it in for 5 seconds (or 30 when you first install it) and then, while holding it in to also press in on the igniter button. If it doesn't light up at first it says that you should keep pressing the igniter button. The first problem is that the knob only turns 90 degrees, not 180.
I have been in the house for about 1.5 years and I know that the previous owner installed the fireplace, but it worked fine last year so I didn't know that it was supposed to turn 180 degrees. I tried lighting the pilot light using the instructions in the manual by turning the knob 45 degrees and also 90 degrees, but the pilot light never lights up. I can see a spark when I press the igniter button, but I never smell any natural gas. I checked the gas lines and all of the valves to the fireplace are set to allow gas to go to the fireplace. I also do not smell gas in any other parts of the house either. I do not know when the pilot light went out, but I know that it was on for all of last winter without any problems. I am something of a novice with home repair, but I do learn fast. Is there anything else that I can check or try, or is it time to call in a HVAC professional?
The control valve likely does move the 180 degrees but not as you're thinking.
Many fireplace valves operate in a similar fashion.
The 0 point is the PILOT posistion and if you push the control valve in and turn it clockwise ( right) 90 degrees ..... this will be the OFF position.
From the OFF position ......
turn control knob counterclockwise to the PILOT position and press in for five seconds......... longer if need be ....... while pressing the Ignitor button.
If it doesn't light or goes out while holding the control knob in .... there may be a problem with the valve or the orifice in the pilot line connection.
When the pilot lights ........ keep the control knob pushed in for around 30 seconds and release the knob...... making sure the knob springs back .... the plilot should be a nice strong blue flame and contacting the thermocouple probe next to the pilot light flame
If the pilot goes out repeat the process again.
Once the pilot stays lit .....
move the control knob counterclockwise to the ON position and the burner should light.
As you see it should move 180 degrees.
If it refuses to light or stay on there may be a problem with some debris in the orifice or the valve itself.
If it does light and stay on for a while then goes out there may be a problem with the thermocouple probe. This probe keeps the valve open enough just to allow the trickle of gas needed for the pilot flame to burn.
Hopefully this makes sense and helps.
