I'm selling a vacant house that has gas fire logs and can't figure out its operation. I've seen them lit a year or so ago. The control has an "off" position, then slightly to the left is an "IGN" position, just to the left of that is a "PILOT" position, and rotated all the way at the bottom of the dial is the "ON" position. I can see where the pilot is, and I even see what appears to be the little wire igniter. But putting the knob in any position (including with the pilot button depressed) does not appear to activate either the igniter, or the hissing sound of any gas. At all positions I also tried to manually light the pilot or burners with no luck. I also intend to go back just to make sure there is not some kind of shutoff valve in the pipe leading up from the basement. What is the correct sequence for firing these up? Also with the igniter I see some light gage wires, but what is the electricity source that actually creates the electrical spark?
Advise and thanks.
