plumbing system to the house. All soldering materials and piping must be compatible with 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 lime 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 (fig. 1-4) in Section V, “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 (fig. 1-4) and pressure relief valve warning in Section V, “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 (fig. 3) “Recommended Piping for Power Failure Freeze Protection” in Section V 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.

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. Refer to the suggested piping diagrams (fig. 2 & 4) in Section V to be used as a guide.

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 part# 239-44511-00 for the electronic manifold control for the first and second water heater and part# 239-44512-00 for the wiring harness for each additional water heater to be controlled. Instructions are included with these parts. Use the piping diagram in figure 4 in Section V as a guide.

NOTICE

Take care when using pipe dope or Teflon 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.

IGI-180C, IGI-180R specifications

Bradford-White Corporation is a well-known name in the water heating industry, offering a range of reliable and efficient products. Among its noteworthy offerings are the IGI-180R and IGI-180C indirect water heaters. These models exemplify the company's commitment to quality and innovation, featuring robust designs and cutting-edge technologies.

The IGI-180R and IGI-180C units are designed to provide a consistent supply of hot water for residential and commercial applications. Both models have a storage capacity of 180 gallons, making them ideal for settings that require large volumes of hot water, such as restaurants, schools, and larger households. Their large tanks ensure minimal wait times and a reliable hot water supply, even during peak usage periods.

One of the key features of the IGI series is their indirect heating capability. Instead of relying on electric elements or gas burners, these heaters use a separate boiler or heating system to provide the necessary heat. This allows for more efficient operation, as the water is heated more evenly and effectively. The models integrate seamlessly with existing boiler systems, making them an excellent choice for those looking to upgrade or expand their hot water capabilities without extensive modifications.

Both the IGI-180R and IGI-180C incorporate advanced insulation technology, minimizing heat loss and improving energy efficiency. The high-density foam insulation encases the tank, keeping the water hot for longer periods and reducing energy costs associated with reheating. This insulation also contributes to a longer lifespan for the unit, as it reduces the wear and tear on the heating systems.

Another pivotal characteristic of these units is their durable construction. Bradford-White utilizes high-quality materials and rigorous manufacturing standards, ensuring that the IGI models withstand the test of time. The tanks are constructed from heavy-duty steel with a glass lining that protects against corrosion and sediment buildup, enhancing the longevity and performance of the water heater.

Lastly, both models come equipped with a range of safety features, including an integrated Pressure Relief Valve and a temperature control system. These elements safeguard against overheating and pressure issues, ensuring safe operation.

In conclusion, the IGI-180R and IGI-180C indirect water heaters by Bradford-White Corporation stand out for their efficient, reliable, and durable design. With advanced heating technology, excellent insulation, and robust safety features, they are a smart investment for any hot water demand scenario.
