:
This fireplace is only certified to work with certain BDM Pro-Form and Duravent flexible direct venting
systems. Not all rigid venting configurations are allowable when using flex venting. Only horizonally
terminated applications will work with a vertical rise between 18” (457mm) and 78” (1981mm) measured
from the top of the unit.
If your vertical rise is between 18” (457mm) and 30” (762mm) use 50-3374 5ft kit.
If your vertical rise is between 30” (762mm) and 78” (1981mm) use 50-3404 10ft kit.
Important Information:
-Do not bend over 90 degrees.
-All horizontal runs should have a minimum 1/4” (6mm) rise per foot for optimal performace.
-Do not allow the inner flex pipe to contact the outer pipe, keep it pulled tight and use spacer springs.
-Spacers are required at the start, middle, and end of each elbow to ensure the gap is maintained.
-Do not add any extensions to the preset kits, if more length is required, use rigid pipe.
