Housing is American steel, not plastic or stainless! Pure steel just like your duct.

Stainless steel can cause oxidation, which can hold moisture, which helps mold grow defeating the purpose of the unit. (electrolysis occurs when two different metals meet and is accelerated when humidity is present). Plastic units have a risk of melting or even burning near furnace heat, never a good idea where flames are present
