DO NOT DRAW UP SECTION WHEN
NIPPLES ARE COCKED. If the torque required
becomes excessive, periodically place a heavy
block of wood over each nipple port and strike as
squarely as possible with several blows to relieve
tension on the draw-up rods.
m. CONTINUE ASSEMBLING SECTIONS IN
THEIR RESPECTIVE ORDER alternating the
draw-up rods from the upper to lower set of
holes in draw-up lugs. Be certain that all sections
are drawn up IRON-TO-IRON at all three (3)
nipple ports.
BE SURE TO APPLY THE FIBERGLASS
ROPE AND SEALANT to the grooves in the
ground joints between adjacent sections as the
boiler operates with a positive pressure in the
firebox and products of combustion will escape
between sections unless they are properly sealed.
The rope and sealant should be applied before
each section is placed on the assembly.
JACKET SUPPORT BRACKETS must be attached
to the appropriate center section during the
assembly process on boiler sizes V1113H thru
V1123H. Check "Section Arrangement" Chart for
location of center section to which jacket support
brackets must be attached (see Figure 8 on Page
18).
Les SUPPORTS DE SUPPORT DE VESTE doivent
être fixés à la section centrale appropriée pendant le
processus d'assemblage sur les chaudières de tailles
V1113H à V1123H. Consultez le tableau «Disposition
des sections» pour connaître l'emplacement de la
section centrale à laquelle les supports de la veste
doivent être fixés (voir la figure 8 à la page 18).
LOCATE JACKET INTERMEDIATE
i.
PANEL MOUNTING BRACKETS
NO. 1, NO. 2 AND NO. 3 IN JACKET
CARTON. Brackets are shipped flat and
Figure 13: Hydraulic Draw-Up of Sections
must be formed by hand, bend as shown in
Figure 10.
ii. WHEN APPROPRIATE SECTION is
being assembled to block, slide brackets
over draw-up rod lugs prior to inserting
draw-up rods, washers and nuts. To prevent
the brackets from turning during the
draw-up process, insert a large punch or
draw-up rod through second hole in each
bracket. Refer to Figures 11 and 12 for
proper location of each bracket and typical
attachment.
n. If a joint springs apart it must be re-drawn tight
within four (4) hours of the time of application
of Silastic to that joint.
o. EXCESS LENGTH OF DRAW-UP RODS must
not extend beyond front and rear sections
to ensure proper fit of jacket, adjust accordingly.
p. AFTER ALL SECTIONS HAVE BEEN
DRAWN UP, THE DRAW-UP ROD NUTS
SHOULD BE LOOSENED UNTIL FINGER
TIGHT AND THEN TIGHTENED ½ TURN
WITH A WRENCH.
q. Now Proceed to Paragraph C of this section,
Hydrostatic Test.
2. ASSEMBLY OF SECTIONS (HYDRAULIC
DRAW-UP)
V1104H through V1112H Section Assemblies
The entire assemblage may be drawn-up at one time
using the hydraulic draw-up equipment providing
the operation is completed within four (4) hours
after application of the sealant.
V1113H through V1123H Section Assemblies
The total assemblage should be first drawn-up into
two (2) sub-assemblies. Each sub-assembly may be
drawn-up at one time using the hydraulic draw-up
equipment providing the operation is completed
within four (4) hours after the application of the
sealant.
