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.
