WARNING
!
PERSONAL INJURY HAZARD
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.
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.
CALCULATE THE DUCTRUN LENGTH
To ensure that the blower performs to its highest
possible capacity, duct work should be as short and
straight as possilbe.
For satisfactory performance the duct run should
not exceed 50 equivalent feet if ducted using the
required minimum 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 in FIGURE 5.

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.

RECIRCULATING INSTALLATIONS
9.0 feet
For recirculating installations, Charcoal Filters are necessary. Remove all
10.0 feet
grease filters and set aside. Attach one charcoal filter to each end of the
0.0 feet
blower. Each charcoal filter attaches to the black grid on the side of the
19.0 feet
blower. Rotate the filter clockwise to install and counterclockwise to remove
(FIGURE 3C). Replace all grease filters.
There are 2 ways to recirculate the Magnum :
1)Use the Recirculation Kit (sold seperately), refer to installation instructions
inside the Recirculation Kit.
2)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). Install at least 15" of metal ducting (fig. 3A and
3B) at the air exit. Run the duct vertically and secure it at the opening cut
out at the top or side of the cabinet or soffit. Installation of a metal grill is
recommended. This duct work must not terminate into a dead air space.
