I have an Astria Aries Direct Vent fireplace. The spark ignitor sparks when I turn on the switch, but the pilot doesn't light. I have tried to purge the air from the line without resolution. Also, no smells of gas anywhere, but I know the gas in my house is working since it is working on the stove/oven. I suspect a gas valve problem or potentially a block in a gas line. My valve is pictured below. When I removed the orange wire and checked the voltage across the line when the spark ignitor was on, I got erratic readings bouncing between 1.3 - 4 V DC and it went to zero when the ignitor stopped sparking. When I had the orange wire plugged in, I measured at the metal where the orange wire connects and on the base of the fireplace and got voltage readings bouncing between 3 - 29 V DC when the ignitor was sparking and going to zero when it stopped. Have I measured the voltage correctly? Are these the readings I should expect? What other diagnostics would you recommend? What would I expect with a bad valve versus an obstructed gas line?
