CAUTION
Boiler sections must be drawn-up on
perfectly level surface or improper
assembly may result.
A. FIELD ASSEMBLED SECTIONS — If the boiler
was ordered to be field assembled, follow the assembly
procedure outlined on the following pages.
1. ASSEMBLY OF SECTIONS (MANUAL DRAW-
UP)
These sections are designed to be drawn together,
one section at a time, using the 9¾” long draw-up
rods (provided) and ordinary hand tools.
Tools required:
(1) ¾” Drive Ratchet
(1) 1-1/16” Socket
(1) 1-1/16” Combination or Open End Wrench
(1) Container of grease, oil or other appropriate
lubricant.
CAUTION
When assembling sections without
hydraulic draw-up equipment, never
assemble more than one section at a time.
a. Place the rear section in its approximate final
position, as outlined in Section I, and support it
with a suitable prop and wedges. See Figure 5.
b. On size 24-03 only— Open target wall carton,
apply Silastic to back of target wall and secure
target wall to rear section.
c. Clean the groove in the ground joint along the
edge of the section with the wire brush.
d. Open the Boiler Assembly Carton(s) and remove
the bottle of adhesive. Using the dauber supplied
in the bottle, apply the adhesive to the groove.
Be sure to use enough adhesive to sufficiently
coat the entire groove surface. If so desired,
a multi-purpose spray adhesive (supplied by
others) may be used instead. HOWEVER,
GREAT CARE MUST BE TAKEN TO
SECTION II - CAST IRON BLOCK ASSEMBLY
ENSURE THAT THE ADHESIVE DOES
NOT COME IN CONTACT WITH THE
NIPPLES OR NIPPLE PORTS.
e. Clean nipples and nipple ports thoroughly with
a de-greasing solvent. Use the Loctite #592
supplied to lubricate the nipples and nipple
ports. Apply the lubricant to the nipples and
nipple ports, then use a brush to disperse it
evenly around the nipples and the nipple ports.
Use approximately 25 ml of Loctite #592 per
flueway [(1) 7” and (2) 3” nipples and their (6)
corresponding nipple ports].
f. Drive nipples squarely into section using
block of wood and hammer, or preferably,
an aluminum head hammer. (Crown offers a
Polyethylene Block for setting the nipples, part
number 330010). Place block over entire nipple
edge and hit the wood with the hammer.
