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.

Figure 46 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!
