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.

d.Copy of the inspection report issued by carrier representative at the time damage is reported to the carrier. The carrier is responsible for making prompt inspection of damage and for a thorough investigation of each claim. The distributor or manufacturer will not accept claims from dealers for transportation damage.
NOTE: When inspecting the unit for transportation damage, remove all packaging materials. Follow local codes when disposing or recycling the packaging material.
Locating The Thermostat
The thermostat should be mounted 5 feet above the floor, on a vibration free inside wall in a room or a hallway that has good air circulation.
Movement of air should not be obstructed by furniture, door, draperies, etc. The thermostat should not be mounted where it will be affected by drafts, hot or cold water pipes or air ducts in walls, radiant heat from fireplace, lamps, the sun, television, etc. Consult the Instruction Sheet packaged with the thermostat for mounting instructions.
All units have one stage of heating and one stage of mechanical cooling. Units which will have economizers may use thermostats with one or two stages of cooling.
IV. Rigging and Handling
CAUTION
To prevent possible property damage, the unit should remain in an upright position during all rigging and moving operations. To facilitate lifting and moving when a crane is used, place the unit in an adequate cable slide.
Important: If using bottom discharge with roof curb, ductwork should be attached to the curb prior to installing the unit. Ductwork dimensions are shown in Amana Roof Curb Installation Instructions.
Refer to the Amana Roof Curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end.

V. Gas Piping
IMPORTANT NOTE: This furnace is factory set to operate on natural gas at the altitudes shown on the rating plate. If operation at higher altitudes and/or propane gas operation is required, obtain and install the proper conversion kit(s) before operating this furnace. Failure to do so may result in unsatisfactory operation and/or equipment damage. (High altitude kits are for U.S. installations only.)
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the furnace is equipped to operate on the type of gas available.
|
INLET GAS PRESSURE |
Natural |
Min. 5.0" W.C., Max. 10.0" W.C. |
Propane |
Min. 11.0" W.C., Max. 14.0" W.C. |
Inlet Gas Pressure Must Not Exceed the Maximum Value Shown in Table 3.
Table 3
The minimum supply pressure should not vary from that shown in the table above because this could prevent the furnace from having dependable ignition. In addition, gas input to the burners must not exceed the rated input shown on the rating plate. Overfiring of the furnace could result in premature heat exchanger failure.
High Altitude Derate (US. Installations Only - Canadian Installations to 4500 Feet Only)
When this furnace is installed at altitudes above 2000 feet, the furnace input must be derated 4% for each 1000 feet above sea level because the density of the air is reduced.
In some areas the gas supplier will derate the heating value of the gas at a rate of 4% for each 1000 feet above sea level. If this is not done, smaller orifices will be required at altitudes above 3500 feet (non-derated natural gas) or 4500 feet (non-derated propane gas).
A different pressure switch will be required at altitudes more than 4000 feet above sea level. This is required regardless of the heat content of the fuel used.
High altitude kits can be purchased depending on the altitude and usage of propane or natural gas. Refer to the high altitude instruction manual included with this furnace to determine which high altitude components to use.
Adjustment of the manifold pressure to a lower pressure reading than what is specified on the furnace nameplate is not a proper derate procedure. With a lower density of air and a lower manifold pressure at the burner orifice, the orifice will not aspirate the proper amount of air into the burner. This can cause incomplete combustion of the gas, flashback, and possible yellow tipping.
Gas Piping
IMPORTANT NOTE: To avoid possible unsatisfactory operation or equipment damage due to under firing of equipment, do not undersize the natural gas/propane piping from the meter/tank to the furnace. When sizing a trunk line as shown in Table 4, include all appliances on that line that could be operated simultaneously.
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the furnace is equipped to operate on the type of gas available.
The gas line installation must comply with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code (ANSI Z223.1).
