Blower speeds for each firing rate are set independently.
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.
)indicates ranges in excess of maximum external static pressure allowable when heating. For satisfactory operation,
The shaded area (
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.
STANDARD ALTITUDE INSTALLATIONS
For installations above 7,000 feet, please refer to your Amana distributor for required kit(s).

MINIMUM CLEARANCES
WARNING
To avoid death, personal injury or property damage due to fire, clearances to combustible
surfaces listed as below must be observed.
Service Accessibility and Unit Connections
• 36 inches front clearance is required for servicing or cleaning.
• Unit connections (electrical, flue, and drain) may necessitate greater clearances than the minimum clearances listed
below.
NOTE: In all cases, accessibility clearance must take precedence over clearances from the enclosure where
accessibility clearances are greater.

FILTERS
NOTE: Filters are required with this furnace and must be provided by the installer. The filters
used must comply with UL900 or CAN/ULCS111 standards. Installing this furnace without
filters will void the unit warranty.
This furnace has provisions for the installation of return air filters at the side and/or bottom return. The furnace will

IMPORTANT NOTES:
1. All furnaces have a redundant gas valve and blower door interlock switch.
2. All furnaces are manufactured for use on 115 VAC, 60 Hz, single phase electrical supply.
3. IMPORTANT: While the data is presented as a guide, it is required to properly size fuses and wires and make electrical
connections in accordance with the National Electrical Code and/or all existing local codes.
4. Performance figures are based on Department of Energy information and requirements under continuous operating
conditions. Performance will vary with weather conditions and use.
5. Drain connections must conform to local codes.
