The Rheem Criterion II is a downflow gas furnace and a member of the RGHL family of products. Rheem publication "Form G11-449 Rev. 6" is an eight-page document that explains how to install the furnace in a closet, alcove, utility room or attic; the furnace is not approved for use in mobile homes. The manual is available for reading online or downloadable as a PDF.
The first page is a cover page. The second page of the manual includes a diagram of the furnace, noting its major parts and a notice about its standard equipment. The third page breaks down all standard data and equipment related to the furnace. It also explains the model identification process, defining each letter used in Rheem model numbers.
Page four features detailed drawings indicating the downflow dimensions of the unit and a table of all dimensions and clearance areas relative to combustible materials. Page five contains blower performance data. Page six gives information on available accessories and the unit's limited warranty, and page seven is blank, allowing a space for notes. Page eight is largely blank, but it provides contact information for Rheem's air conditioning division.Learn more about Heating & Cooling
