Page 8 | SERIES 28A BOILER INSTALLATION AND OPERATION INSTRUCTIONS |
Completed boilers 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.
WARNING: Never leak test the boiler using compressed air! Failure to comply with this warning may result in property damage, severe personal injury or death!
1.Plug all openings in the boiler and fill it with water.
2.Bleed any air off through one of the top tappings then increase the pressure as outlined above.
3.Maintain the test pressure while carefully checking for leaks. If a leak is found it must be eliminated, see Table 4 and supporting text. Once the assembled boiler sections pass the hydrostatic test drain them and remove the plugs from any tappings that will be used in service.
NOTE: The shipping lugs, lifting lugs and metal banding should be removed before installing the jacket on factory assembled sections.
CAUTION: Remove the left jacket panels on fully packaged boilers and ensure that the cleanout covers are secure and gas tight. Loose covers could damage the boiler.
Assembly of
Drilled and tapped steel angles are furnished to provide a level footing, ease of section assembly and a point of jacket attachment.
1.Set the angles as shown in Figure 3. They must be parallel and level. Grout under the angles to provide a continuous bearing surface.
2.Carefully place the back section in position on the angles as shown in Figure 4.
WARNING: The section MUST be fully supported to prevent it from falling! Failure to comply with this warning may result property damage, severe personal injury or death!

3.Clean the hydronic port connector sealing surfaces and the rope grooves with a wire brush to remove any rust or debris.
4.Apply two coats of the spray adhesive supplied with the boiler to the rope groove. Allow time for the first coat to dry before applying the second coat. When the second coat is tacky press the rope into the rope groove. Trim the rope off leaving 1/8 in., 3.2 mm extending beyond the surface of the cast iron section, Figure 5.
