■ Grab-holes in doors to aid in easy door removal and
replacement.
A variety of cooling coils and plenums designed to use with
Rheem Criterion II gas furnaces are available as optional
accessories.
✝A.F.U.E. (Annual Fuel Utilization Efficiency) calculated in accordance with Department of
Energy test procedures.
