An In-Depth Look at the State GS6-50-YBDS-300

When shopping for a new water heater, the details matter. The State gs6 50 ybds 300 is built for reliability, and understanding its components can help you make an informed choice.

Core Specifications and Physical Characteristics

The gs6 50 ybds 300 has a 50-gallon capacity (48 usable), making it ideal for most families of three to four. Its powerful 40,000 BTU natural gas burner ensures a quick recovery, so you’re not left waiting for hot water. The Uniform Energy Factor (UEF) of 0.66 represents a solid balance of performance and value, indicating how efficiently it converts gas to hot water.

Physically, this is a tall model at 59 inches high (73 inches with draft hood) and 22 inches in diameter , weighing around 200 pounds . These dimensions are key for planning installation. It uses standard 3/4-inch water and 1/2-inch gas fittings , simplifying the process for a professional.

Advanced Features for Durability and Safety

State combats tank corrosion with a dual-defense system. The patented Blue Diamond® glass lining provides a tough ceramic shield, while the long-lasting stainless steel CoreGard™ anode rod sacrificially attracts corrosive elements to protect the tank. To maintain efficiency, the DynaClean™ automatic sediment cleaning system prevents mineral buildup that can reduce performance.

Safety is also paramount. The unit is FVIR (Flammable Vapor Ignition Resistant) compliant to prevent the ignition of external flammable vapors, and a push-button Piezo ignitor allows for safe, match-free pilot lighting. Environmentally, the Green Choice® Gas Burner reduces harmful NOx emissions by up to 33%, meeting Low NOx requirements . An intelligent control system with an LED indicator simplifies temperature control and provides diagnostic codes.

Hot Water Performance and Recovery

The key performance metric for your family is the first hour rating (FHR) of 77-91 gallons . This figure represents the total hot water available in the first hour of use. This high FHR means the gs6 50 ybds 300 can handle multiple back-to-back showers and other simultaneous uses. After the initial demand, its strong recovery rate of 43 gallons per hour (at a 90°F rise) quickly replenishes the hot water supply.

From showering and laundry to washing dishes, this water heater is built to keep your daily routine running smoothly. Your actual experience will vary based on groundwater temperature and usage habits, but this unit is designed to keep up with typical household demands.

If you’re considering upgrading, we at AAA Home Services can help you find the right fit. We offer a range of new water heaters and can assess your specific needs to ensure you get the performance you’re looking for.

Installation, Efficiency, and Warranty for the gs6 50 ybds 300

Understanding the long-term performance, installation needs, and warranty of the gs6 50 ybds 300 is key to your investment.

Understanding Energy Efficiency and Environmental Impact

The 0.66 Uniform Energy Factor (UEF) indicates how efficiently the gs6 50 ybds 300 converts natural gas into hot water, helping to keep monthly utility bills reasonable. Beyond cost savings, this model is an environmentally responsible choice. It features State’s patented Green Choice® Gas Burner , which reduces harmful nitrogen oxide (NOx) emissions—a key component of smog—by up to 33%. Choosing this Low NOx compliant water heater means better air quality for the community without sacrificing performance.

Direct Vent Installation Requirements

The gs6 50 ybds 300 features a direct vent system, a key differentiator from traditional models. This sealed system draws combustion air from outside and exhausts it directly back outdoors. This design eliminates indoor ventilation concerns, improves indoor air quality, and avoids using conditioned indoor air for combustion, making it ideal for tightly sealed homes.

Due to the complexity of this specialized venting, professional installation is essential to ensure safe and efficient operation. A trained technician will correctly handle the gas connections, venting configuration, and safety controls.
