Sounds like you don't like doing things according to instructions. Those washers come with the propane conversion kit and are for directing the heavier propane gas upward slightly. Other manufacturers redirect propane installations in other ways but this is still an industry standard.

I stopped using goodman when a tech. told me to put a 1/4 inch washer under the burner ass. to properly direct the flame into the extanger. Also had a lot of small component recalls within 1 year. JUNK if you ask me. Amana not so bad in my book.
If you really have an issue, state it. Otherwise, just making rude brand bashing remarks about a brand of equipment is very unprofessional and makes it seem like you do not know much about the HVAC industry.
