Flame Sensor (Qualified Servicer Only)

Under some conditions, the fuel or combustion air sup- ply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator causing a drop in the flame sensing signal. If this occurs, a qualified servicer should carefully clean the flame sensor with emery cloth or steel wool. After cleaning, the microamp signal should be in the range listed in Table 1A.

Induced Draft Motor

Condenser Fan Motor Lubrication

The condenser fan motor bearings are permanently lu- bricated and do not require additional lubrication.

Ignitor (Qualified Servicer Only)

If the ignitor and the surrounding air are at about 70° F and the ignitor wires are not connected to any other elec- trical components, the resistance of the ignitor should not exceed 200 ohms. If it does, the ignitor should be replaced.

Compressor

The compressor motor is permanently lubricated and hermetically sealed. It does NOT require oiling.

Flue Passages

At the start of each heating season, inspect, and if nec- essary clean the furnace flue passages.

Cleaning Flue Passages (Qualified Servicer Only)

1.Shut off electric power and gas supply to the fur- nace.

2.Remove burner assembly and disconnect the gas line and remove the manifold brackets from the par- tition panel.

3.Remove the induced draft blower and the collector box from the partition panel.

4.Remove tube inserts and turbulators from heat ex changer.

5.The primary heat exchanger tubes can be cleaned using a round wire brush attached to a length of high grade stainless steel cable, such as drain cleanout cable. Attach a variable speed reversible drill to the other end of the spring cable. Slowly rotate the cable with the drill and insert it into one of the primary heat exchanger tubes. While reversing the drill, work the cable in and out several times to obtain sufficient cleaning. Repeat for each tube.

6.When all heat exchanger tubes have been cleaned, replace the parts in the reverse order in which they were removed.

7.To reduce the chances of repeated fouling of the heat exchanger, perform the steps listed in Startup and Adjustment, Section XII.

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.
