With a magnifying glass we could read and decipher the instructions, it was tough to see the colors on the orifices but we did find them by the #'s (also on side of orifice).
There was a challenge making sure the orifice didn't fall into the stove, under the burner surface, when installing new orifice. We put some double stick tape on a sharpie marker and lowered it into the small opening. We did it and the stove works fine with our new orifices. We are happy with the quality and end result of our product.
