Crown Boiler 24-12 Section II Cast Iron Block Assembly, Assembly of Sections Manual DRAW- UP

SECTION II - CAST IRON BLOCK ASSEMBLY

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

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.
