PLAN THE INSTALLATION
The Nova chimneys
are adjustable and
designed to meet
varying ceiling heights
as indicated in FIGURE
2. The chimneys
can be adjusted for
ceilings between 7'
8 1/2" and 9' 9 1/2"
depending on the
distance between the
bottom of the hood and
the cooktop (distance
x in FIGURE 2).

For best results, use no more than
three 90° elbows. Make sure that
there is a minimum of 24" of straight
duct between elbows if more than
one is used. Do not install two

PLAN THE INSTALLATION
This rangehood can be installed as either ducted
or ductless. The blower can be vented through the
wall or ceiling. To vent through a wall, a 90° elbow is
used. When installed ductless, the rangehood vents
out of grates on the sides of the chimney. Ductless
installations require a Ductless Conversion Kit,
available from your dealer.
This rangehood can be used with an optional remote
blower. If a remote blower is used, then the internal
blower must be removed and discarded. Both blowers
cannot be used together. The remote blower connects
to the rangehood using a separate wiring cable not
supplied with the rangehood. The wiring cable should
be installed at the same time as the ductwork.
WARNING! BEFORE MAKING ANY CUTS OR
HOLES FOR INSTALLATION, DETERMINE WHICH
VENTING METHOD WILL BE USED AND CAREFULLY
CALCULATE ALL MEASUREMENTS.
CALCULATE THE DUCTRUN LENGTH
The ductrun should not exceed 35 equiva-
lent feet if ducted with the required minimum
of 3 1/4" by 10" rectangular duct and 55
equivalent feet if ducted with 9" round duc-
twork (Remote blowers require 9" round
duct). Calculate the length of the ductwork
by adding the equivalent feet in FIGURE
3 for each piece of duct in the system An
example is given in FIGURE 4.

from the hood's exhaust opening as possible.
WARNING
Because of the weight and size of the rangehood canopy, two or
more people are needed to move and safely install the rangehood
canopy. Failure to properly lift rangehood could result in damage
to the product or personal injury.
PERSONAL INJURY HAZARD
For shorter ceilings, have the chimney cover(s) cut at a sheet metal
shop. For higher ceilings, there are two extension kits available
depending on how much height is required. For very tall ceilings, the
Cathedral Chimney Kit includes a new 4ʼ upper chimney and a new
4ʼ lower chimney. For installations where only 1” - 20” of additional
height is needed, the High Ceiling Chimney Kit includes a new 40”
upper chimney which would replace the 20” upper chimney that came
with the hood.
