Thermostat Adjustment

General Operation continued-

The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the “” mark on the thermostat dial (approximately 120°F [49°C]) as indicated below. Rotate

the thermostat dial clockwise to increase the temperature setting.

Rotate the thermostat dial counterclockwise to decrease the temperature setting. Adjust the dial until the minimum acceptable temperature is achieved (See figure below for approximate temperature settings).

DANGER

Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 135° F (57° C). To protect against hot water injury, install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch water lines. A licensed plumbing professional or local plumbing authority should be consulted.

Note: This water heater is equipped with an energy cut out device to prevent overheating. Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance and call a qualified service technician.

Note: Whenever the water heater is filled with cold water, condensate will form on the cool tank surface and drops of water will fall on the hot burner and combustion chamber surfaces producing a “sizzling” noise.

Condensation is normal and does not indicate a leak. It will disappear when the tank becomes heated.

DS150S, DS140S specifications

Bradford White Corp is renowned for its commitment to quality and innovation in the water heating industry, and its DS140S and DS150S models exemplify this dedication. Designed for residential and light commercial applications, these models bring efficiency, performance, and advanced technology to the forefront of water heating solutions.

One of the standout features of these models is Bradford White's patented Hydrojet Total Performance System. This system optimizes the heating process by creating a more efficient flow of water within the tank, reducing sediment buildup over time. This results in improved energy efficiency and longer tank life, as well as maintaining the quality of the water being heated.

In addition, both models are equipped with Bradford White's Vitraglas® interior coating, which provides exceptional protection against corrosion. The Vitraglas coating is not only durable but also enhances the longevity of the tank, ensuring reliable performance for years to come.

Another notable characteristic of the DS140S and DS150S is their advanced electronic gas control system. This feature allows for precise temperature regulation, ensuring that the water remains at the desired temperature while reducing energy consumption. The intuitive interface simplifies operation, making it accessible for users of all skill levels.

Safety is paramount, and Bradford White incorporates various protective measures within these models. The flame arrestor design enhances the safety profile by preventing flashback, while the temperature and pressure relief valve ensures that the tank operates within safe limits.

Furthermore, the DS140S and DS150S models are designed with ease of installation and maintenance in mind. Compact designs and versatile venting options allow these water heaters to fit into tight spaces, making them suitable for various installation environments.

In summary, Bradford White Corp’s DS140S and DS150S models combine innovative technology, efficiency, and safety features, making them excellent choices for anyone in need of a reliable water heating solution. With robust construction, high-performance capabilities, and advanced features, they are sure to meet the demands of both residential and light commercial applications.
