CAUTION
Due to the fact that the sections are top heavy, it is
absolutely necessary that the back section be supported
in such a manner as to prevent its falling and causing
potential serious bodily injury while preparing to add the
next section. One such way would be to insert a piece of
3" x 36" piping in the lower port.
NOTE
Some sections may need shims under support feet to align
with other sections.
Stand the back section in place with the feet on and in the
angle iron rails. Support the section as required to prevent it
from falling forward or rearward. Clean hydronic gasket
recesses and rope groove with a stiff wire brush. Apply
spray-on adhesive (supplied with the boiler) to rope groove
to hold wicking in place during assembly.
CAUTION
Do not spray adhesive into the hydronic seal ports.
Apply a length of wicking avoiding bends and twists. Be sure
ends extend past the cleanout cover opening. (See FIGURE
2) Place the upper and lower hydronic seals in the recessed
section taking care not to dislodge the rope or the hydronic
seals. Inspect the alignment of the sections through the open
ports and, if properly aligned, install the draw rods with nuts
drawn hand-tight. (See FIGURE 3.) Plumb the sections before
applying torque to the upper right and lower left draw rods.
Maintain finger-tight torque on upper left and lower right draw
rods.
FIGURE 2
IMPORTANT
The upper and lower ports should be drawn up metal to
metal around the outside of the hydronic seal. Metal to
metal conditions will not occur at any other location.
Avoid excessive torque on upper left and lower right
draw rods, which may warp the section. See FIGURE 3
for correct alignment of the seal.
Assemble additional sections as described above.
After draw rods are hand tight, torque as shown in TABLE 3.
5. COMBUSTION AND VENTILATION AIR
An adequate supply of air for the boiler room must be provided
to allow complete combustion of fuel and ventilation of the
room to avoid excessively high ambient temperature. Air inlet
by natural ventilation directly from the outside shall have
total free area of not less than one sq. in. per 14,000 BTU
per hour of input of all fuel burning appliances in the boiler
room.
Where combustion air must be obtained through ducts, see
ANSI/NFPA 31 or ANSI Z223.1 for requirements.
If mechanical combustion air supply is required, the system
must be approved by the local authorities, and should provide
at least 30 CFM per gallon of oil and 0.25 CFM per MBH of
gas input to the boilers.
Ventilation air, if required, must be in addition to the
combustion air quantities called for above.
6. ASSEMBLY OF SECTIONS
When boilers are delivered to the job site, each item should
be inspected closely for possible shipping damage. Scars or
nicks in the port sealing surfaces may allow leakage. Do not
attempt to use any section that has been damaged in the
port seal area.
When ready to commence assembly, recommended on a
level pad, place the angle rails in position parallel with each
other with the 2" legs on the floor and measuring 25-21/32
inches outside dimension. Be sure to align the center of the
boiler with the center line of the pad. If no pad is provided,
shim and grout under the angles to make them level and
provide support along the full length. See FIGURE 1. Clean
hydronic gasket recesses and rope groove with a wire brush,
taking care not to damage machine surface.
See TABLE 2 for proper location of sections.
