    Does the WaterFurnace Series 5 have Formishield Plus for their air coil or is this an error in WaterFurnace's literature?

    Waterfurnace Series 5 units have transitioned over the past few years to all aluminum aircoils to prevent formicary corrosion. Some models by capacity may still be copper tube/aluminum fin and are standard with Formishield. I am not sure which models, I don't think they publish as it is a running change over. A phone call to them may settle this.
