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.

WARNING

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the furnace before shutting off the electrical supply.

CAUTION

On PGC48 - 60 and PGB58 Only: To avoid damage to the compressor, engage the electrical disconnect switch to the compressor unit four hours prior to operating air conditioner after the electrical disconnect is off for a prolonged period of time (during vacation, etc.). This time lapse allows the compressor crankcase to attain a proper operating temperature.

WARNING

If the information in this manual is not followed exactly, a fire or explosion may result causing property damage, personal injury, or death.

WARNING

This product contains or produces a chemical(s) which may cause death or serious illness and which are known by the State of California to cause cancer, birth defects or other reproductive harm.

CAUTION

This unit should not be used as a “construction heater” during the finishing phases of construction on a new structure. This type of use may result in premature failure of the unit due to extremely low return air temperatures and exposure to very dirty atmospheres.

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.

III. General Information

WARNING

Improper installation, repair, operation or maintenance of this product may result in property damage, personal injury, or death from hazards such as fire, explosions, smoke, soot, condensation, electric shock or carbon monoxide.

This unit is approved only for an outdoor installation. To assure that your unit operates safely and efficiently, it must be installed, operated, and maintained in accordance with these installation and operating instructions, all local building codes and ordinances, or in their absence, with the latest edition of the National Fuel Gas Code. (ANSI Z223.1).

The heating and cooling capacities of the unit should be greater than or equal to the design heating and cooling loads of the area to be conditioned. The loads should be calculated by an approved method or in accordance with ASHRAE Guide or Manual J - Load Calculations published by the Air Conditioning Contractors of America.

Transportation Damage

All units are securely packed in shipping cartons approved by the International Safe Transit Association. The carton should be checked upon arrival for external damage. If damage is found, a request for inspection by carrier agent should be made in writing immediately.

The unit should be carefully inspected upon arrival for damage and bolts or screws which may have loosened in transit. In the event of damage, the consignee should:

1.Make notation on delivery receipt of any visible damage to shipment or container.

2.Notify carrier promptly and request an inspection.

3.In case of concealed damage, carrier should be notified as soon as possible-preferably within 5 days.

4.File the claim with the following supporting documents within the 9-month statute of limitations.

a.Original Bill of Lading, certified copy, or indemnity bond.

b.Original paid freight bill or indemnity in lieu thereof.

c.Original invoice or certified copy thereof, showing trade and other discounts or reductions.

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.

If using a fork lift, see Figure 2 for location of fork prongs. Make certain prongs support unit weight.
