potable water. Unions should be installed on both the hot and cold water lines for future servicing and disconnection of the water heater. Install a shut-off valve in the cold water supply line.

2.In order to service the water heater in the event the heat exchanger needs to be flushed of mineral deposits, tee fittings with shut-off valves and service connections to hoses should be installed. Also, install a shut-off valve to the hot water supply to isolate the service tee fittings. A plumbing installation kit, which includes these fittings and a pressure relief valve, is available from your supplier. Refer to the piping diagrams in Section IV, “Water Connections”.

3.Install a pressure relief valve on a tee connection from the hot water outlet piping from the water heater. Refer to the piping diagrams (Figure 6 and Figure 7) and pressure relief valve warning in Section IV, “Water Connections.”

4.In cold climates, where piping can freeze during an extended power failure, drain solenoid valves should be installed on the cold and hot water supply lines to allow water to drain from the water heater when power is interrupted. Refer to the piping diagram (Figure 8) “Recommended Piping for Power Failure Freeze Protection” in Section IV, and contact your Bradford White dealer if assistance is needed.

5.If this water heater is installed in a closed water supply system, such as the one having a back- flow preventer in the cold water supply, provisions must be made to control thermal expansion. DO NOT operate this water heater in a closed system without provisions for controlling thermal expansion. Warranties do not cover damages from thermal expansions, such as pressure bulges and/or deformities. Your water supplier or local plumbing inspector should be contacted on how to control this situation.

6.Purge the cold water line prior to connecting to the water heater to remove debris. Debris will clog the mesh strainer of the inlet filter. The inlet strainer prevents debris from damaging the flow sensor or clogging the coil. It may need to be cleaned periodically and should be cleaned after the initial operation. DO NOT operate the water heater without the filter in place. In areas where sediment may be periodically present in the water supply, a Y-type strainer (#20 mesh) or cartridge filter should be installed on the cold water inlet to the water heater to prevent the water heater fine mesh strainer from getting plugged and restricting water flow.

7.After installation of the water lines, open the main water supply valve and fill the water heater. While the water heater is filling, open several hot water faucets to allow air to escape from the water system. When a steady stream of water flows through the faucets, close them and check all water connections for possible leaks.

8.This water heater may also be connected to a circulating pump or storage tank for increased flow capacity during high demand periods.

9.Commercial installations may require more than one water heater piped together in a manifold to supply enough capacity for high temperature and high water flow applications. Special controls are available from your Bradford White supplier for operating more than one water heater together. These controls stage the operation of the water heaters for the flow rates and control the amount of flow through each water heater. Order p/n MSA-2M for the electronic manifold control for the first and second water heater and p/n MSA-2S for the wiring harness for each additional water heater to be controlled. A maximum of (5) water heaters can be connected together. Alternatively, to connect only (2) water heaters, an EZConnectTM harness, p/n REU- EZC-1US, can be used. Instructions are included with these parts.

NOTICE

Take care when using pipe dope or thread sealing tape to avoid clogging the inlet screen and water flow sensor. Wipe off excess pipe dope from threads before connecting to the water heater.

Commercial dishwashers will require either more than one water heater, or a storage tank to supply a sufficient volume of hot water.

Bradford White Corporation is renowned for its innovative solutions in the water heating and storage sector, offering a range of high-quality products designed for residential and commercial applications. Among its standout offerings are the TG series models, including TG-237E-N(X)A, TG-150E-N(X), TG-180E-N(X), TG-237E-N(X), and TG-199E-N(X). These models are specifically designed to maximize efficiency while providing reliable hot water delivery.

One key feature of the TG series is its high Energy Factor (EF) ratings, which signify exceptional energy efficiency. The models employ advanced technologies that not only reduce energy consumption but also minimize environmental impact. These products typically include a highly efficient burner system that enhances heat transfer, ensuring that users enjoy maximum hot water availability without incurring high utility costs.

Each model is crafted with robust materials, designed to withstand the rigors of everyday use. For example, the tanks are typically built from durable steel and feature an advanced glass lining that protects against corrosion and extends the lifespan of the unit. Additionally, these models are equipped with high-quality insulation that helps retain heat, further improving efficiency.

The TG series also emphasizes user convenience and safety. Many units come with a user-friendly control system that allows for easy temperature adjustments and monitoring. This is complemented by built-in safety features such as automatic shut-off capabilities, helping to prevent overheating or other potential hazards.

Another characterizing aspect of the TG series is its flexibility in installation. These water heaters are designed to fit various spaces and configurations, ensuring that they can meet the needs of different households or commercial facilities. Additionally, some models are compatible with both natural gas and propane, offering versatility in fuel options.

In terms of technology, these Bradford White water heaters include features such as electronic gas control systems that provide precise temperature management, and advanced airflow designs that optimize combustion efficiency. This focus on technology ensures that the TG series is not only reliable but also a smart choice for cost-conscious consumers looking to reduce their energy bills.

In summary, the Bradford White TG series, with models like TG-237E-N(X)A, TG-150E-N(X), TG-180E-N(X), TG-237E-N(X), and TG-199E-N(X), stands out for its robust design, efficiency, and advanced safety features.
