You should try to seach info on wiki first.
And not finding the info was the reason I asked here. It may be that I placed the drain on the wrong side of the oven.
Neat problem. I assume IC2 is also allowed.
Actually, Most of IC2 generators are disabled. There is no use for creosote other than using it to make lubricant.
Alternately, you can pipe it into a tank (Quantum Tank) and use some automation trickery to remove/blow up the tank. Not sane/ideal, obviously.
The first tier Quantum Tank requires components that can be made with 480 EU/t....i am still on LV (making aluminium).
I did try the drain cover attached to a pipe, which in turn is connected to a BC tank (BC pipes are disabled btw)...but that didn't work, Thinking about it now, I did have it attached to the side instead of the bottom of the oven....that may have been the reason it hadn't worked.
