Figure : Lower Tie Bar Installation
Repeat operation until all vertical channels have
been installed. Using an open end wrench and
ratchet with socket, tighten all 5/8” bolts and nuts to
secure frame brackets to casting legs.
13. Locate Jacket Carton(s), marked ‘JC-2’ and remove
contents. Install lower tie bars into slotted ‘I’
openings on lower frame brackets to provide proper
spacing between frame channels, refer to Figure 22.
Determine proper location of tie bar by comparing
it’s length to the distance between brackets. Lay
each tie bar on the floor at that location along both
sides of boiler.
Step a . Starting at the rear and working to the front,
hold the first tie bar on a slight angle and pass the
end through ’I’ opening in rear bracket as shown
in Figure 22.
step b.
Lower the tie bar between brackets as
shown in Figure 22.
step c.
Pull tie bar back and engage opposite end
through ‘I’ opening in front or center section
bracket as shown in Figure 22.
step d.
Engage slotted end of hook over lip of ‘I’
opening and push downward to lock position.
If necessary, spread brackets by pushing or
pulling vertical channels until tie bar drops into
locking position, see Detail ‘A’ in Figure 22. For
multiple tie bars, each consecutive bar must be
rotated end for end so the top flanges oppose
each other, for entry into ‘I’ opening, see Detail
‘B’ in Figure 22. Complete process to front
bracket and repeat on opposite side.
