PLAN DUCTWORK INSTALLATION
For Ducted Installations Only:
Begin planning ductwork by deciding where duct will run
between hood and outside. For best performance, use
shortest possible duct run and a minimum number of elbows.
In more complex situations, 3-1/4” x 10” duct can be
converted to round duct by means of a transition. FIGS 1A 1E show several choices.
FIG. 1C
ROOF CAP
3-1/4" X 10" DUCT
FIG. 1C: Ducting straight up through roof using 3-1/4” x 10”
duct. For single story installations.
FIG. 1D
ROOF CAP
FIG. 1A
WALL CAP
FIG. 1A: Ducting directly through outside wall. If wall cap is
used directly off back of hood, check to make sure that
damper flap in damper/duct connector on hood does not
interfere with damper flap in wall cap. If it does, remove flap
on hood damper/duct connector.
