I recently moved into a home that was build in 2005, so this is somewhat newer equipment.

There is a wall switch and obviously it does nothing when I switch it.

I removed the bottom tile and exposed the mechanics and there seems to be only two things to adjust, and on/off switch and the a red knob that is hooked up to the let the gas in or out. There is electricity going to the unit but other than that I can't figure out how to get the pilot light to light and get the fireplace going. Thanks for helping out a newbie to this forum, much appreciated.

here a pic for refreance, the only markings I found was on the on and off switch box (Honeywell).
