SERIES 28A BOILER INSTALLATION AND OPERATION INSTRUCTIONS

9.Assemble the rest of the sections following steps 3 through 8 above.

10.Hydrostatically test the boiler by following the instructions on page 8.

11.While the boiler is being filled confirm that all of the draw rods are properly torqued and that there are no leaks.

12.If any leaks are found tighten the draw rods on that section until the leak stops.

Cleanout Cover Installation

1.The cleanout covers come insulated from the factory. Inspect the covers to ensure that the insulation is not damaged or missing. If it is call the Smith Customer Service Department.

2.Trim the 1/2" rope that's sticking out around the cleanout opening flush with the castings to insure an air-tight seal, see Figure 5.

3.Install the cleanout cover bolts from the inside of the cleanout cover and start the nuts, Figure 7.

4.Insert the cleanout cover and tighten the nuts to 15 ft lbs, 21 Nm.

5.Apply a bead of high temperature silicone caulk around the perimeter of the cleanout cover to ensure an air tight seal.

Burner Mounting Plate Installation, Figure 8

1.Apply two coats of the spray adhesive supplied with the boiler to the rope groove on the plate. Allow time for the first coat to dry then apply the second coat. When the second coat is tacky lay the 3/8 rope into the rope groove and press it into place.

2.Screw the four 7/16-14 x 2 1/2" studs into the tapped holes in the boiler front section, Figure 8.

3.Install the burner mounting plate insulation block in the burner opening in the front section of the boiler. The small observation port cutout must be on the top, left side.

4.Align the four holes in the burner mounting plate with the 7/16" studs and force the burner insulation block inward until the studs extend far enough through the burner mounting plate holes so the nuts can be started. Lightly tighten the nuts.

5.Carefully insert the 1/4-20 x 5" machine screws through the holes in the burner mounting plate and insulation block, Figure 8. Reach through the inside of the burner opening and install the stainless steel fender washers and nuts and snug the nuts down.

CAUTION: The burner insulation block must be supported from the inside to prevent it from tearing. Don't force the bolts through the block or over tighten the nuts or the block with be damaged!
