Boiler Baffle System

The 94 Series 4 baffle system is a combination of two
types of baffles. The first baffle type is for the two 2nd
flue-ways (outer), and the second baffle type is for the
two 3rd flue-ways (inner). See Figure 23. The flue-
2
way doors can only be opened one at a time. Baffle
assembly and installation starts on either side of the
boiler, then repeated on the other side of the boiler
2nd flue-ways (outer):
A telescoping-style, elongated C-channel is inserted
3
into the 2nd flue-ways across the third side fins from
the bottom See Figure 25, page 33.The 2nd flue-
way baffle is designed to extend 5" for every 6"-wide
intermediate section of the boiler. This baffle comes
with hardware (two sheet metal screws, and either
four or eight clevis pins) to telescope the mating

C-channel parts into the proper length for each boiler
size See Figure 22 and Table 9
3rd flue-ways (inner):
Left-hand and right-hand sub-assemblies are
assembled together in the 3rd flue-ways to create a flat,
rectangular plate assembly See Figure 29, page 36
The assemblies are created in combinations of four,
five, or seven rectangular plates at the center of each
intermediate casting These groups are connected
together by four side rails to ensure a rectangular plate
is at the center of each intermediate casting for the
entire length of the boiler
Each boiler size has a unique width of rectangular
plate Thus, the right-hand and left-hand sub-
assemblies come with a range of connection holes
to create the proper width of baffle for the boiler size.
See Table 9 and Figure 27, page 35
