Ditto on the improper install.. They are very specific in the installers manual. Someone should have read it.
One of my faults is I read manuals. :)
Lol That's so me too and that's how I found that it was a install issue. The manual states and I quote: Always install furnace through an exterior wall
DO NOT install furnace on materials that restricts return air, such as directly on carpet, or soft material (like vinyl). If you must install furnace on carpet or soft material, install furnace on cleats or on a wood or metal panel extending the full width and depth of furnace plus minimum clearance to combustibles
