GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

NOTE: All assembled boiler sections shall pass the hydrostatic tests prescribed in Section IV of the ASME Boiler and Pressure Vessel Code.

CAUTION: Do not connect any boiler controls during the pressure test or they will be damaged!

Completed boiler blocks must be tested as follows:

Steam Boilers - the assembled boiler sections shall be subjected to a hydrostatic test pressure of not less than

45psig, 315 kPa.

Water Boilers - the assembled boiler sections shall be subjected to a hydrostatic test pressure of not less than 1 1/2 times the maximum allowable working pressure.

The hydrostatic pressure shall not exceed the required test pressure by more than 10 psig, 70 kPa during the test.

Maintain the test pressure while carefully checking for leaks. If a leak is found it must be eliminated. Once the cast iron sections have proven to be watertight drain them and remove the plugs from any tappings that will be used in service.

FLUE COLLECTOR INSTALLATION

A single draft hood is used on the 5 through 12 section boilers, two are used on the 13 to 21 section boilers. The Draft Hood(s) are packed in a box marked with a number from 63187 to 63194.

Apply two coats of the spray adhesive to the top of the casings where the flue collectors will rest. When the second coat of adhesive is tacky place strips of ceramic blanket on the castings, Figures 46 and 47A & B.

Flue Collector Ceramic Blanket Placement

WARNING: The ceramic blanket must be overlapped as shown in Figure 47A & B to prevent the escape of flue gases. Failure to properly seal the flue collector to the boiler sections can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

This design not only enhances the boiler's lifespan but also ensures that it maintains optimal performance over time, even in rigorous conditions.

The GB300 series is equipped with advanced technologies that contribute to its efficiency and ease of use. For instance, the boilers incorporate a flexible firing system that allows for a range of firing rates. This adaptability ensures that the boiler can efficiently meet varying heating loads. Additionally, the use of a multi-pass heat exchanger design maximizes heat transfer, significantly improving overall efficiency and reducing fuel consumption.

Another key characteristic of the GB300 boilers is the user-friendly control system. The integrated control panel provides operators with real-time monitoring and management capabilities, allowing for precise adjustment of temperature and pressure settings. This feature not only enhances operational efficiency but also aids in maintaining safety standards.

The GB300 series also emphasizes safety, featuring multiple levels of protection, including low water cut-off, high-pressure switches, and safety valves. These safety mechanisms ensure reliable operation and minimize the risk of operational hazards, providing peace of mind for operators and facility managers.

Versatility is another remarkable attribute of the Smith Cast Iron Boilers GB300 series. These boilers can be used in various configurations, whether as a standalone unit or as part of a more extensive heating system. This flexibility makes the GB300 series suitable for diverse applications and facility sizes.

In summary, the Smith Cast Iron Boilers GB300 series is a powerful heating solution that combines durability, efficiency, and advanced technology. Its robust cast iron construction, flexible firing capabilities, and comprehensive safety features make it an ideal choice for those seeking reliable heating systems in demanding environments. The GB300 series stands out as a testament to Smith's commitment to quality and innovation in the boiler industry.
