Proper Piping Practice

Checking The Gas Piping

CAUTION

To avoid the possibility of personal in- jury, property damage or fire, the follow- ing instructions must be performed re- garding gas connections and pressure testing:

•This unit and its gas connections must be leak tested before placing in opera- tion. Because of the danger of explosion or fire, never use a match or open flame to test for leaks. Never exceed speci- fied pressures for testing. Higher pres- sure may damage gas valve and cause overfiring which may result in heat fail- ure.

•This unit and shut-off valve must be dis- connected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 PSIG (3.48 kPa).

•This unit must be isolated from the gas supply system by closing the manual shut-off valve during any pressure test- ing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG (3.48 kPa).

WARNING

To avoid personal injury or property dam- age, be sure there is no open flame in the vicinity during air bleeding procedure.

There will be air in the gas supply line after testing for leaks on a new installation. Therefore, the air must be bled from the line by cracking open the ground joint union until pure gas is expelled. Tighten union and wait for five minutes until all gas has been dissipated in the air. Be certain there is no open flame in the vicinity during air bleeding procedure. The unit is placed in operation by closing the main electrical disconnect switch for the furnace.

Tanks And Piping for Propane Gas Units

WARNING

Personal Injury Hazard

Failure to detect a propane gas leak could result in an explosion or fire which could cause death, serious personal injury, or property damage.

Iron oxide (rust) can reduce the level of odorant in propane gas. A gas detecting device is the only reliable method to de- tect a propane gas leak. Contact the lo- cal propane supplier about installing a warning device to sound an alert if a gas leak should develop.

All propane gas equipment must conform to the safety standards of the National Board of Fire Underwriters (See NBFU Manual 58).

For satisfactory operation, propane gas pressure must be 10 inch W.C. at the furnace manifold with all gas ap- pliances in operation. Maintaining proper gas pressure depends on three main factors:

1.Vaporization rate, which depends on (a) tempera- ture of the liquid, and (b) wetted surface area of the container or containers.

2.Proper pressure regulation. (Two-stage regulation is recommended from the standpoint of both cost and efficiency.)

3.Pressure drop in lines between regulators, and be- tween second stage regulator and the appliance. Pipe size required will depend on length of pipe run and total load of all appliances.

Complete information regarding tank sizing for vapor- ization, recommended regulator settings and pipe siz- ing is available from most regulator manufacturers and propane gas suppliers.

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.
