NOTE:
1.All airflow is dry coil.
2.Installation is to be adjusted to obtain temperatures rise within the range specified on the rating plate.
3.The above chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the rating plate. The shaded area (
) indicates in excess of maximum external static pressure allowable when heating.
4.This chart is for units installed at 0-2000 feet. At higher altitudes, a properly derated unit will have approximately the same temperature rise at a particular CFM, while ESP at that CFM will be lower.
5.Cooling operation may require a different fan speed than heating operation. For details, see Wiring Diagrams.
6.Above chart is applicable for both vertical and horizontal airflow.

Locating The Unit
WARNING
To avoid possible equipment damage, fire, personal injury, or death, the following points must be observed when installing the unit.
All Installations:
•For proper flame pattern within the heat exchanger and proper condensate drainage, the unit must be mounted level.
•The unit should be as centralized as is practical with respect to the air distribution system. This unit is for outdoor installation ONLY!
•The flue outlet hood must be at least 12 inches from any opening through which flue gases could enter a building, and at least three feet above any forced air inlet located within ten feet. The economizer/manual outdoor air intake/motorized outdoor air intake and combustion air inlet mounted on the unit are not affected by this restriction.
•To avoid possible corrosion of the heat exchanger, do not locate the unit in an area where the outdoor air (i.e., combustion air for the unit) will be frequently contaminated by compounds containing chlorine or fluorine. Common sources of such compounds include swimming pools and chlorine bleaches, paint stripper, adhesives, paints, varnishes, sealers, waxes (which are not yet dried) and solvents used during construction and remodeling. Various commercial and industrial processes may also be sources of chlorine/fluorine compounds.
•To avoid possible illness or death of the building occupants, do NOT locate outside air intake device (economizer, manual outdoor air intake, motorized outdoor air intake) too close to an exhaust outlet, gas vent termination, or plumbing vent outlet. For specific distances required, consult local codes.
•Allow clearances from the enclosure as shown in Figure 1 for fire protection, proper operation, and service access. These clearances must be permanently maintained.
•The combustion air inlet and flue outlet hoods on the front of the unit must never be obstructed. If used, do not allow the economizer/manual outdoor air damper/ motorized outdoor air damper to become blocked by snow or debris. In some climates or locations, it may be necessary to elevate the unit to avoid these problems.
•When the unit is heating, the temperature of the return air entering the unit must be between 50° F and 100° F.
Ground Level Installations Only:
•When the unit is installed on the ground adjacent to the building, a level concrete (or equal) base is recommended. Prepare a base the same physical size as the unit or slightly larger and 3 inches thick.
•The base should also be located where no run-off of water from higher ground can collect in the unit.
•The feet on the unit may not be removed.
Rooftop Installations Only:
•To avoid possible property damage or personal injury, the roof must have sufficient structural strength to carry the weight of the unit(s) and snow or water loads as required by local codes.
•If horizontal air delivery is used, the unit may be installed directly on wood floors or on Class A, Class B, or Class C roof covering material, provided that the feet on the unit are not removed.
•To avoid possible personal injury, a safe, flat surface for service personnel should be provided.
•If vertical air discharge is used and the unit is installed on combustible flooring or class A, B, or C roofing material, then the Amana roof curb (PRC3A or PRC5A) listed on the unit nameplate is required.
