Installing the 3rd Flue-Way Baffles

1 The 3rd flue-way assembled baffles come in
combinations of four, five, and seven rectangular
flat plates, with small side flanges affixed between
four side rails
2 The bottom of each baffle is indicated by the half-
circle lifters spot-welded onto the side rails
3 Confirm that the quantity of available assembled
baffles matches the quantity of intermediate
sections in the boiler
a Example: A 2094 boiler has one front casting,
one rear casting, and 18 intermediate castings
Therefore, a 2094 boiler requires 18 flat-plate
baffles in the 3rd flue-ways.
4 Insert one baffle combination (four, five, or seven)
into the 3rd flue-way at a time.
a Use four clevis pins to connect each additional
flat plate baffle assembly through the mating
holes at the end of each rail
b Make sure to have the cotter pin end of the
clevis pin to the inside of the baffle (see
Figure 30)
c Insert cotter pins into the ends of the clevis pins
5 Continue to insert and connect additional four,
five, or seven baffle plate assemblies until
the installed quantity matches the quantity of
intermediate castings for the boiler size
6 Once all flat plate baffles have been inserted
and connected, retrieve the 3rd flue-way baffle
locator bracket from the baffle hardware bag. See
Figure 31
a Use the 1/4" bolt and nut to connect the
locator bracket to the lower right-hand rail hole
connection on the right-hand side of the boiler,
or the lower left-hand side rail hole connection
on the left-hand side of the boiler
b Only one locator bracket is required for each of
the 3rd flue-ways.
c Push the entire 3rd flue-way baffle connected
combination back until the locator bracket
lands against the casting face that divides the
3rd and 2nd flue-ways. See Figure 32.
d There will be leftover locator brackets after
assembly and installation Only two locator
brackets are required per boiler, one bracket
for each 3rd flue-way. See Figure 32.
7 Close the flue-way door.

IMPORTANT
If only one side of the boiler has been completed, open
the other flue-way door, and repeat the entire process
for the 2nd and 3rd flue-way on the other side.
