NOTES:

•CFM information in the above table is with high velocity, permanent filter(s) as shipped with the furnace. If the furnace is shipped with two side return filters, this table assumes both filters are used.

• All furnaces ship as high speed for cooling. Installer must adjust blower speed as needed.

•For most jobs, about 400 CFM per ton when cooling is desirable.

•This chart is for furnaces installed at 0 - 4000 feet. At higher altitudes, a properly derated unit will have the same temperature rise at a particular CFM, while the ESP at that CFM will be lower.

•The shaded area ( )indicates ranges in excess of maximum external static pressure allowable when heating. For satisfactory operation, external static pressure should not exceed 0.5” W.C. The data for 0.6” W.C. to 0.8” W.C. is shown for air conditioning purposes only.

•The dashed (-----) areas indicate a temperature rise not recommended for this model.

•The installation must be adjusted to obtain a temperature rise within the range listed on the furnace nameplate.
