|  "GMP FURNACE"
, posted Mon 18 Feb 21:20:  
I'm a General Contractor so I don't know everything about FAUs and I'm not trying to start a fight. I have heard that Goodman had a lot of problems with GMP series. I pulled the manual today on the GMP series, and it said the GMP is a multi-positional universal discharge (up, down, left, right).
So there must be some field configuring required.(ie rotate burners, flip ID blower, choose flue port, flop junction box, and the like.
Are the problems associated with the GMP series, Goodman's fault or is the machine "too complicated" to configure and install correctly?
Edit: Turned out the "manual" I pulled was really not an install manual, just kind of a brosure/spec sheet. So I can't as yet, GOTSP with you, regarding configuation information you mentioned.

The short answer to your question is "both".
The furnace was not nearly as hard to configure as you're imagining.
It was a very simple furnace, but it's design was not very tolerant of...anything, really. Now how many guys do you think actually read that manual, and followed it's instructions?
On the other hand, it was a cheap furnace built of very cheap components, which Goodman eventually had lots of problems with, regardless of how well installed it was.

the GMP is a horrible furnace with a heat exchanger that is held together with these rings that are pressed on. they cannot take much in the heat range category. real POS.... should come with a parts bag. thankfully they don't make them anymore.

Thanks Static,
Do you think it's smart to make a real good universal or is that an oxymoron? Is it legal? I guess warranty issues would be astounding?
The GMH has a 3 position option. What am I taking about anyway? production, production, production................big deal huh.
If you got the time, one more thing, what makes a furnace, a great furnace, the board or insulating the house?
I still haven't finished the bubble wrap. Too busy now, tinkering with a 1983 Brown Stove Works 20" sparky range in the in-law unit. She wants me to put a pressure switch in the manometer port for an LED on the console.
Can I get a X"wc switch, low side 5"wc (what pressure should I use?) port size looks like female tire valve. Is this possible? We'd like tho keep the relic, but its kind of hard to see if the individual burner valves are all the way off. I'd have to run a copper gas loop from low to P/S to low, then figure some way to power the LED. Altenative: get a gauge, put some green and red paint on it and put that in the console. Not really worried about warranty issues at this point...SUMB (Snickering Under My Breath)

Most high efficiencies are multi positional now. As long as they are engineered right it doesn't really matter what position they are in as long as whatever position they are put in they are installed properly. The heat exchanger static mentioned was used widely by a lot of manufacturers and has caused bad reps for a lot of them which is kinda funny because that heat exchanger the cheap pos that it is is still going into new furnaces today. Engineering and quality materials are what makes a furnace good in my book. That being said if a furnace isnt put in right it doesn't matter how well thought out the design was.
