I think I will give them a call and ask to have the draft test done anyway.
Even professionals can be wrong. If I were your installer and you asked me to follow the instructions I would do it. Sometimes we get caught up in standard practices and are in a hurry to move on to the next job. But we should be going by the book, even if our standard practice is at odds with the manual.
