shipped in a left and right half

correct width for the boiler size
c Use the four sheet metal screws for the
assembly, with two screws at each end

of the left and right halves of the baffle to create
the required width for the boiler size The left-
hand side must be the front baffle. Refer to
the figures on this page and Table 9, page 32

on the top and bottom of the baffles as the two
halves are brought together

metal screws
a These screws go in the bottom of the first and
last baffle of the combination being assembled.
b The screw tips must always point in toward the
other rectangular baffles to keep sharp points
away from the ends

the other rectangular baffles.
