I have a Majestic DVR33 that was installed 7 years ago. I had turned the fireplace (gas & pilot light) off for the summer and I went to turn it back on yesterday. I can get the pilot on but as soon as I turn the knob to "on" the pilot goes out. I've tried multiple times, turning the gas off overnight and trying again, leaving the pilot going for 10min or so and then turning the knob, all with the same result. Any suggestions or ideas would be much appreciated.
