CAUTION

Before manually operating the valve, make sure that a drain line has been attached to the valve to direct the discharge to an open drain. Failure to take this precaution could mean contact with extremely hot water passing out the valve during this checking operation.

FLUSHING PROCEDURE FOR LIME SCALE REMOVAL FROM HEAT EXCHANGER

The amount of calcium carbonate (lime) released from water is in direct proportion to water temperature and usage. The higher the water temperature or water usage and the harder the water (more dissolved calcium carbonate), the more lime deposits are dropped out of the water. This is the lime scale that forms in pipes, water heaters and on cooking utensils.

Lime accumulation reduces the efficiency and longevity of the heat exchanger coil and will cause the water heater to malfunction. The lime scale may need to be periodically removed from the heat exchanger (indicated by the “LC” code on the remote display). The usage of water softening equipment greatly reduces the hardness of the water. However, this equipment does not always remove all of the hardness (lime). The heat exchanger may occasionally need to be flushed to clear out the lime deposits. Use the following procedure and diagram (fig. 13) to flush the heat exchanger and remove the lime scale.

1.Disconnect power to the water heater.

2.Close valves in the cold water inlet and outlet supply.

3.Connect PVC hoses (may use garden hose to the drain valve outlet fittings). Connect a circulator pump to the hose connected to the cold water inlet. See figure 11 for hose and circulator connections.

4.Pour 4 gallons of fresh vinegar into a 5 gallon bucket.

5.Place the ends of the hose into the bucket.

6.Open the drain valves to the hose fittings.

7.Turn on power to the circulating pump and allow the vinegar to circulate through the heat exchanger coil for at least 45 minutes. Heavily limed heat exchangers may require several hours.

8.Turn off power to the circulating pump.

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.
