19HE SERIES BOILER
BOILER SECTION ASSEMBLY INSTRUCTIONS
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. Clean
hydronic gasket (port) recesses and rope groove with a
wire brush, taking care not to damage machine surface.
When ready to commence assembly, on a level pad,
place the angle rails in position parallel with each other
with the 2-1/2 inch side on the floor and measuring
25-21/32 inches apart (outside dimension). Be sure to
align the center of the boiler with the centerline 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.
Proper location of sections.

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. Clean hydronic gasket (port)
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.
NOTE: Do not spray adhesive in the hydronic seal
ports.
Apply a length of wicking avoiding bends and twists.
Make sure ends extend past the cleanout cover open-
ing. Place the upper and lower hydronic seals in the
recessed (port) 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 1.) Plumb the sections before applying torque
to the upper right and lower left draw rods. Maintain fin-
ger-tight torque on upper left and lower right draw rods.

After draw rods are hand tight, torque as shown in TABLE 1.
The upper and lower ports should be drawn up evenly until iron to iron contact is made around the outside of the
hydronic seal (port) area. Metal to metal conditions will not occur at any other location.
Important
Avoid excessive torque on upper left and lower right draw rods, which may warp the section. See FIG-
URE 1 for correct alignment of the seal.

Prepare additional intermediate sections and install
in the same manner described above. Be sure each
section is properly sealed against water leakage and
flue gas ex-filtration. Be certain the angle rails remain
level and provide support for each section as it is
assembled. Check each section for vertical position.
When all sections, including the front and back
sections are in place, check all draw rods to insure iron-
to-iron contact at ports. DO NOT APPL Y EXCESSIVE
TORQUE.
