Note: All "B" model units have aluminized heat exchangers on second bank or downstream furnaces. One year warranty applies. Optional 409 or 321 stainless steel heat exchangers may be substituted for aluminized heat exchangers on second bank furnaces. Five year warranty then applies for units with first and second bank 409 ss heat exchangers or ten year warranty for 321 ss exchangers.
