" diameter shipping tie rods. Do not use to draw sections together.
8. Draw sections together until metal-to-metal contact is made around machined port
opening. See
Figure 10
.
a. Oil threads on three draw rods. Install washer and nut on end to be tightened. Use
nut only on other end.
b. Uniformly draw sections together, starting at washer/nut end.
c. Draw rods should be torqued to a range of 100-120 ft/lbs. Do not back off draw
rods.
d. Metal-to-metal contact will be achieved around port opening. See
Figure 10
. If a
gap does exist, it should be no greater than .032". Check with feeler gauge.
9. Follow steps 2 through 8 for remaining intermediates and left end section.
Check sealing
rope
Check sealing rope of each section before proceeding to next section. Boiler
must be sealed gas-tight to prevent possibility of flue gas spillage and
carbon monoxide emissions, causing severe personal injury or death.
End section
must be
plumb
End section must be plumb. After erecting 1st intermediate section, check
both sections for plumb. Failure to plumb sections may cause misaligned
piping and breeching, resulting in minor property damage.
Verify metal to
metal contact
at ports
If for any reason gap around port opening exceeds .032", check for rope
extending from rope grooves, dirt on port openings or sockets, or
misaligned lugs. If corrections are made and gap still exists, contact your
Weil-McLain distributor or sales office before continuing installation.
Failure to correct this situation could cause seal failure, resulting in severe
personal injury, death or substantial property damage.
