I can't keep the pilot lit. I replaced the thermal couple and confirmed when I hold down the pilot valve it will generate up to 700 to 800 mv. As soon as I release the pilot valve the gas cuts out. Not sure what the problem is. When I first started it up it ran for about 10 minutes the quit and I have not been able to get it running since.
Thanks
