requirements differ by boiler model, see Table 2.
TABLE 2: BAFFLE USAGE
Figure 5C: Top View - Burner Swing Door Fully Closed but Not Properly Secured or Sealed
NOTE: Read caution statement before proceeding.
CAUTION
These bafes will generate higher efciencies
and lower stack temperatures. Under certain
conditions, a lower gross stack temperature
entering the chimney has the potential to
be cooled below the dew point and create
condensate on interior surfaces. Flue gas
condensate is corrosive, which requires
special consideration and must be addressed
immediately.
DO NOT install bafes until you have read
Section V, "Venting" completely.
