Stack Extension
Fan Assembly
If fan requires a stack or stack extension, install on
fan before installing nozzle and windband. Place
gasketing between any sections, blower housing and
initial stack. Use lifting lugs to position each piece
into place. Attach stack or stack extension to blower
housing using 316 stainless steel bolts (provided)
through flanges aligning bolt patterns. Use anti-
seize gel (provided) to prevent galling/welding of all
stainless steel fasteners.
