PLAN THE DUCTWORK
The Cristal slideout rangehood is designed to offer wide
flexibility of installations. The rangehood can be ducted
vertically or horizontally through a 3 1/4" X 10" rectangular vent.
The unit can also be installed in a recirculating configuration.
FIGURES 1 and 2 show horizontal and vertical ducting
installations for this unit. FIGURE 3 shows recirculating
installation.

VERTICAL DUCTING
For recirculating installations, filter kit 6093033 is necessary.
The charcoal filters must be inserted behind the grease filters.
The back of the charcoal filters are supported by a small pin
on the outside edge and a metal flange on the inside edge.
The front of the charcoal filters have plastic tabs that lock
into place when the filter is pushed upward. The plastic grille
supplied with the kit can be used to cover the duct opening as
illustrated in FIGURE 3.
The ductwork length should not exceed 26 feet. For best
wall cap
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.
Calculate the length of the ductwork by adding the equivalent
feet listed in FIGURE 4 for each piece of duct in the complete
system. An example is given in FIGURE 5.
