Found this today. An updraft furnace installed upside down.

Randy,
I have seen one of these before. The installation manual was there and said this configuration was allowed as long as the clearances were correct.

Its probably one of those South American furnaces. Just like the clock-wise drains they have down there, all of their furnaces burn in the opposite direction also.
But really, wouldn't you think the upside down lables on the side would have been a clue

I don't buy that even for a minute. The furnace pictured cannot possibly operate safely as it's installed.

of course it can be correct…check the model # of the furnace and see if it has a MP in it ,which means multi position,I have installed many of them…

I,m an HVA/C contractor and not only is that not a downflow furnace, but the evaporator coil is installed in the return. That heat exchanger will be rusted out in short order from condensation.

That sure is a furnace capable of a downflo application. Several manufacturers make multi position furnaces. I know who makes that furnace. The “A” coil is on the return side. But can you tell me what about this will shorten the life of the heat exchanger?

As Anatol already mentioned, check the manufacturer’s installation instruction to verify if the installed position is allowed or not.

Bill: the reason that furnace can’t be used as a downflow is if you look at it the draft inducer is below the heat exchanger. Heat rise’s, this creates two problems - first problem is flue gas rises and the combustion intake for the burners is the highest open point. Second problem is the excess heat will cause the furnace to limit out, and the heat exchanger will burn through. You also can’t install a furnace on its back.
The reason you can’t put the evaporator on the return is you will be chilling the heat exchanger 20* below the air temp inside the heat exchanger. It will sweat on the inside of the heat exchanger and rust it out quickly. The evap always goes below an electric furnace, don’t want to give water a chance to drip down on electric coils.
