A Coil Upside Down!

[jonroth]

Today I installed a UV lamp into my neighbors Lenox Furnace A Coil. The unit is attic mounted horizontally. When I removed the A coil's inspection cover I found the Coil to be reversed. The Vertex of the A was facing the heating chamber of the furnace. Is this a common practice? Does it restrict the air flow and efficiency?

read the installation manual lennox will tell u exactly how they want it.i had one backwards in an air handler and it snapped the drainpan. but it depends on whether its left to right or right to left how they want it
