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 elbows
together. If you must elbow right away, do it
as far away from the hood's exhaust opening
as possible.

CALCULATE THE DUCTRUN LENGTH
The ductrun should not exceed 35 equivalent feet
if ducted with the required minimum of 6" round
duct. Calculate the length of the ductwork by
adding the equivalent feet in FIGURE 4 for each
piece of duct in the system. An example is given
PLAN THE DUCTWORK
The Magnum rangehood is designed to offer wide
flexibility of installations. The rangehood can be
ducted vertically or horizontally through a 6" round
vent. The unit can also be installed in a recirculating
configuration. FIGURES 1 and 2 show vertical
and horizontal installations for this unit. FIGURE
3 shows recirculating installation.
The Magnum requires 6" round ductwork. To
ensure that the blower performs to its highest
possible capacity, ductwork should be as short
and straight as possilbe.
WARNING! BEFORE MAKING ANY CUTS OR
HOLES FOR INSTALLATION, DETERMINE WHICH
VENTING METHOD WILL BE USED AND CAREFULLY
CALCULATE ALL MEASUREMENTS.

RECIRCULATING INSTALLATIONS
For recirculating installations, Charcoal Filters are necessary. Remove all
grease filters and set aside. Attach one charcoal filter to each end of the
blower. Each charcoal filter attaches to the black grid on the side of the
blower. Rotate the filter clockwise to install and counterclockwise to remove
(FIGURE 3C). Replace all grease filters. Some ductwork must be installed to
exhaust the rangehood back into the kitchen, either at the top of the cabinet
(FIGURE 3A) or at the face or side of the soffit (FIGURE 3B). This duct
work must not terminate into a dead air space.
