5. Clean the area around the flow ports and in the seal
recess. Use solvent and a clean cloth to thoroughly
clean all of the sealing surfaces. Remove all foreign
matter to assure a water tight seal when the sections
are drawn together.
6. Place a Flow Port Gasket in each of the three flow
port recesses as shown in Figures 2.1 and 2.2.
7. Apply spray adhesive in the rope groove around the
perimeter of the section.
8. Place the sealing rope completely around the rope
groove, being careful not to stretch the rope. Extend
the rope from 1/4" to 1/2" past the end of the groove
on both sides of the cleanout opening on top of the
section. This will assure a gas tight seal when the
cleanout cover plate is applied.
9. Apply a bead of silicone sealant around each flow
port as shown in Figure 2.3. Do not get sealant on
the flow port gaskets.
10. Lift up the Rear Section and move into position on
the steel channels on the boiler foundation.
11. Screw a 3" pipe at least 30 inches long into the
lower 3" tapping on the back of the Rear Section as
shown in Figure 2.4. Place a block under the pipe as
shown in the figure and use as a brace during
assembly.
12. Place a Plain Intermediate Section on the floor and
prepare as above.
13. Carefully place the Intermediate Section against the
Rear Section and visually line up the flow ports as
close as possible.
14. Insert a tie rod with one nut and washer applied
into each of the four tie rod lugs. See Figures 2.5
and 2.6.
15. Place the nut and washer on the other end of the tie
rod and draw finger tight.
