Place nipples in ports taking care to seat them squarely to
prevent cocking. Figure 10.
When pulling sections together with tie rods, always insert
tie rods in holes nearest to nipple ports. Move tie rods to
proper location, if necessary, only after sections are fully
pulled together. Oil or lubricate threads, insert tie rods
in lugs with washers under nuts and tighten uniformly
and evenly so that sections are pulled parallel as they go
together. When all sections are pulled up locate tie rods in
alternating pairs of upper and lower holes between adjacent
sections. Figure 11.
Be sure both ends of completed section assembly are
resting evenly on both ends of base.
Apply furnace cement at the joints of the sections front, top
and back. Putty should also be applied where the sections
join the base. Figure 12.
Place necessary plugs and control wells in correct locations.
Plug all other tappings, leaving air vent in top of one of
end sections, and connect water. Fill boiler with water
until it runs out the air vent. Hydrostatically test boiler in
accordance with applicable codes. Check for leaks before
continuing with assembly Drain and remove unnecessary
plugs.

Attaching Draft Hoods
Attach the draft hoods to the boiler sections after
applying boiler putty to the top of the boiler sections
where the hoods and sections meet. Use j-bolts to
attach the fronts of the draft hoods to slots in the
section fl anges. Figure 13.
