Here are a couple suggestions and cautions, yes you can operate the solenoid valve directly from the controller-but if pilot light is out and you are not there to shut it down, probably would go boom when it lights off from something else. Would recommend using a factory made pilot burner as it might be a bit more blow out proof than a drilled plug, you can find them on ebay for about $17-$18 or less in the auctions. Most will have larger orifices for NG so it would burn better if the orifice was switched to the smaller LP orifice, cost is between $10-$15 each. If you are using high pressure burners you should use a needle valve in the supply line to the pilot to regulate flame size. If you purchase the pilot burner with the ignition/flame sense electrode you can always wire it up later when you get an ignition module.
