Base Assembly
The 300, 400 and 500 boilers are the basic models. The 300
model has (6) burners, the 400 model has (8) burners and
the 500 model has (10) burners. Combinations of the basic
models are used to assemble the 600 through 3000 models.
Refer to Chart 3 for the proper order of assembly. When two
or more bases are used to assemble the boiler, be sure the
tops of the bases are even.
The bases are fastened together with 5/16 cap bolts and
nuts. Insert two bolts in the front posts and two in the rear
posts as shown in Figure 7A . After bases are fastened
together, install the base end panels. These end panels
must be installed before assembling sections Figure 7B.
Important: After bases are assembled check to be sure
they are level.
Section Assembly
The sections may be started from either the left or right end
of the base.
Place the end section on the base with the center-line of the
section directly over the joint of the base end closure. With boilers
having two or more bases, as you progress be sure the parting
line (center-line of section) of the intermediate sections fall on
the junction of the two bases. Figure 8.
Before beginning, clean nipples and nipple ports. Coat
nipples and nipple ports with pipe joint compound
or other good sealant and keep them clean. Figure
