PLACE THE BOILER SECTIONS
A. PREPARATION
1. Check the level of the Boiler Base using a spirit level.
Make sure the base is level and that the base panels
are aligned within plus or minus 1/16" (2 mm).
2. Check the area around the Flow Ports (Figure 3.1).
Use solvent and a clean cloth to thoroughly clean the
flat surfaces and recesses. All foreign matter must be
removed to assure a proper seal when the sections
are drawn together.
B. PLACING THE SECTIONS
1. Begin by placing the Left Hand End Section on the
left end of the base. The upper flow port goes
toward the front of the boiler as shown in Figure 3.2.
2. Slide the section to the back of the base until the cast
lug on the bottom of the section under the lower
flow port is against the base back panel. Keep the
section upright by a supporting prop or other means.
3. Align the parting line of the section with the seam
between the Base End panel and the Base Front
Panel as shown in Figure 3.3.
4. Apply Hi-Temp rope seal by spreading a thin coat of
spray adhesive in the grooves on each end of the
section. Place the rope in the grooves. Do not stretch
the rope. The longer rope goes in the front groove.
NOTE: The ends of each rope must extend 1/2"
(13 mm) beyond the top and bottom.
5. Place the Flow Port Gaskets in the recesses provided
(see Figure 3.1). Do not use adhesive.
6. The following steps must be followed to insure that
no damage is done to the tie rod lugs. A 0-100 ft.-lbs.
(0-136 N
· m) torque wrench is required.
a. Place an Intermediate Section on the base and
slide it carefully against the Left Hand End
Section.
b. Align the flow ports from front to back, as close
as possible.
c. Insert a tie rod into each of the lugs on each
section and apply a nut and washer to each end
of the tie rod.
d. Before tightening, check the vertical alignment of
the sections using a spirit level (see Figure 3.4).
Make sure they are square with the Base.
3. PLACE THE BOILER SECTIONS
Gaskets will be damaged by petroleum or its
derivatives. Completely remove all solvent residue
before placing gaskets.
Do not use petroleum based compounds in the
boiler.
CAUTION
The sections are heavy and must be supported
securely.
