Please refer to the unit wiring diagram for electrical con- nections. When installed, the unit must be electrically grounded in accordance with local codes or in the ab- sence of local codes with the latest edition of National Electrical Code, ANSI/NFPA No. 70.

WARNING

To avoid death or personal injury due to electrical shock, wiring to the unit must be properly grounded.

CAUTION

To avoid personal injury or property dam- age due to fire, use only copper conduc- tors.

The best protection for the wiring is the smallest fuse or breaker which will hold the equipment on the line during normal operation without nuisance trips. Such a device will provide maximum circuit protection. DO NOT EX-

CEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DATA PLATE.

Be sure line voltage connections are made through weatherproof fittings. All exterior power supply and ground wiring must be in approved weatherproof con- duit. Low voltage wiring from the unit control panel to the thermostat requires coded cable. For ground level and rooftop wiring refer to Figure 8.

Unit Voltage

The unit transformer is factory connected for 230V op- eration. If the unit is to operate on 208V, reconnect the transformer primary lead and induced draft blower mo- tor leads as shown on the unit wiring diagram.

Heat Anticipator Setting

The heat anticipator in the room thermostat must be correctly adjusted to obtain the proper number of heat- ing cycles per hour and to prevent the room tempera- ture from overshooting the room thermostat setting. Heat anticipator must be set at 0.8 amps.

CAUTION

To prevent improper and dangerous op- eration due to wiring errors, label all wires prior to disconnection when servicing controls. Verify proper operation after servicing.

Vll. Circulating Air and Filters

Airflow Conversion

Units can easily be converted from horizontal to vertical airflow delivery.

Units will ship from the factory ready for horizontal air- flow. If conversion to vertical airflow is necessary, pro- ceed as follows:

IMPORTANT: Be sure to save the flue hood assembly (cardboard box) which is shipped in the return air com- partment of the unit.

•Remove panels from the bottom of the unit, saving the mounting screws.

•Remove insulation from outside of supply duct cover. No insulation should face outside.

•Relocate the panels on to the side of the unit, se- curing with the screws removed earlier.

•The unit will deliver the same amount of air whether the airflow is vertical or horizontal. For details, see the fan tables on Pages 2 - 5.

CAUTION

To avoid possible fire, the cardboard shipping support (located behind the supply panel) must be removed before operation.

IMPORTANT: Be sure to save the flue hood assembly which is shipped in a cardboard box in the return air compartment of the unit.

PGB58B, PGC(24-60)B specifications

Amana, a trusted name in heating and cooling, offers several high-efficiency gas furnace models, including the PGC(24-60)B and PGB58B. These furnaces combine innovation, reliability, and advanced technology to provide an optimal heating solution for any home.

One of the standout features of the Amana PGC(24-60)B is its modulating heating capability. This technology allows the furnace to operate at different heating levels based on the home’s demands. Instead of simply turning on and off, the PGC adjusts its output to maintain a consistent temperature, promoting energy efficiency and comfort. This not only reduces energy consumption but also minimizes temperature fluctuations, providing a more comfortable indoor environment.

The PGB58B model is designed with a focus on efficiency, boasting an Annual Fuel Utilization Efficiency (AFUE) rating of up to 96%. This means that a higher percentage of the fuel used is converted into heat, making it one of the most efficient choices available. The combination of high-efficiency design and advanced components makes the PGB58B an excellent option for homeowners looking to reduce their energy bills while enjoying reliable heating performance.

Both models come equipped with a durable casing, ensuring longevity and performance. The rust-resistant and heavy-gauge steel construction protects against harsh weather conditions, making them suitable for various climates. Additionally, they feature a multi-speed blower motor, which optimizes airflow and enhances comfort by evenly distributing warm air throughout the home.

Advanced diagnostics and self-monitoring capabilities are integral to these models. The built-in diagnostic system enables quick identification of performance issues, allowing for timely maintenance and reducing repair costs. Furthermore, these furnaces are designed to be compatible with smart home technology, allowing homeowners to control their heating systems remotely and maximize energy efficiency.

In summary, the Amana PGC(24-60)B and PGB58B gas furnaces stand out for their innovative features and commitment to energy efficiency. With modulating heating, high AFUE ratings, durable construction, and smart technology compatibility, they offer reliable heating solutions that ensure comfort while keeping energy costs low. Homeowners can feel confident in their investment, knowing they have chosen a furnace that prioritizes both performance and sustainability.
