Reset After Lock-out

Should ignition not be achieved after three tries for any reason, it will be necessary to reset the electronic igni- tion module. To reset, it is only necessary to turn the thermostat below room temperature for thirty seconds, and then reset it to the desired temperature. The fur- nace may also be reset after lockout by disengaging the electric disconnect switch to the furnace for thirty sec- onds.

Secondary Limit Control

On the PGC and PGB series, a second limit control is placed on the blower scroll that will open if the blower should fail, causing elevated temperatures at the con- trol. The reason for elevated temperatures at the control should be ascertained and repaired prior to resetting this manual reset control. The secondary limit control is lo- cated behind the front center panel on the blower scroll. (Figure 15).

Gas Valve

1.Close the manual gas valve external to the furnace.

2.Turn off the electrical power supply to the furnace.

3.Set the room thermostat to its lowest possible set- ting.

4.Remove the right hand door on the front of the fur- nace by removing screws.

5.This furnace is equipped with an ignition device which automatically lights the burner. Do NOT try to light burner by any other method.

6.Turn the gas control valve knob to the OFF position. Do not force. (Figure 16).

7.Wait five minutes to clear out any gas.

8.Smell for gas, including near the ground. This is im- portant because some types of gas are heavier than air. If you have waited five minutes and you do smell gas, immediately follow the instructions on Page 6 of this manual. If you have waited five minutes and you do NOT smell gas, turn the gas control valve knob to the ON position. (Figure 16).

9.Replace the door on the front of the furnace.

10.Open the manual gas valve external to the furnace.

11.Turn on the electrical power supply to the furnace.

12.Set the thermostat to desired setting.

NOTE: There is a one minute delay between thermo- stat energizing and burner firing.

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.
