How do I make a coke oven in Minecraft FTB?

I stand on the hose. I would like to do a coke oven in Minecraft FTB, but all the instructions I try don't work.

Did you leave out the block in the middle?

I found two instructions.

Once the coke oven is made with coke brick. So from clay, brick and sand.

And once Coke Oven Brick made of sand and brick. However, I couldn't make the Coke Oven Bricks.

The whole thing is 3x3x3 and I left out the one in the middle.
