READ AND SAVE THESE INSTRUCTIONS
INSTALLATION PRECAUTIONS
e high degree of craftsmanship in the construction and finish of your hood requires careful handling to ensure proper installation.
• Do not remove your hood from its carton until you are ready to hang it.
• Do not store your hood anywhere other than within the carton. If it is necessary to remove your hood from the carton, arrange it on a blanket or padded area that will protect your hood from scratches or indentations.
• Do not lift the hood by its utensil rail. Place your fingers under the lower reveal of the hood. Grasp firmly and lift.
• Cotton gloves are preferable. ey will protect the surface from fine scratches and eliminate fingerprints.
• Remove all rings, watches, belt buckles, and jackets (snaps-zippers) to prevent scratch marks.
• Do not remove the cotton flannel from your hood until the installation process is complete. It will be necessary to remove only a small portion on the back-side of a wall mounted hood in order to position in place.
• Located within the hood cavity (behind the baffle filter) are component parts and halogen bulbs.

Toll-Free 1-866-667-8454
CHECK THE INSTALLATION LOCATION
• If your installation has been roughed-in (including ductwork and wiring), be certain there are no obstructions in the way of the mounting, pipes, other wiring, etc.
• If the installation has not been roughed in, check what is needed to create the framing and mounting hardware (allthreads, nuts, etc.). Be sure the location will not interfere with wiring, other utilities, or structural considerations.
WALL MOUNTED HOODS
1. Use 2x4s, Unistrut or Angle Iron, to construct the framing. e considerable weight of the hood makes this necessary.
2. Mark the center location of the hood. Install two 2x4s (wide side down), Unistrut or Angle Iron, across ceiling joists with outer edges aligned with the existing ceiling joist.
3. Drill two 7/16"" diameter holes in the 2x4s, Unistrut or Angle Iron, the same distance apart as the nuts in the top of the hood, plus the finished drywall thickness. is ensures the hood is tightly fitted against the wall. Install wooden spacers if necessary to ensure the top of the hood is flush with the ceiling.
CHOOSE THE INSTALLATION METHOD
ere are several different methods available to mount the hood: the Unistrut, Angle Iron, Frame In, Wall Mount and Rough-In Plate Mount, which can be used for both indoor and outdoor applications. Please check the model options for the suggested methods of your installation. Each hood type and site requirements are presented as follows.

REMOVE VENTILATION TIPS
1. Leave Appliances such as Ranges, Cooktops, Barbecue Units, Grills, etc., require adequate ventilation. Hood should be large enough and Cooking Appliances located so that the Hood overhangs the Cooking Surface as much as possible.
2. Consult a competent Kitchen Designer or Ventilation Engineer for proper hood size and C.F.M. requirements.
3. Provide make-up air input to the kitchen so exhausted air is not drawn through the furnace unit or down through the chimney.
4. Locate the Cooking Area for minimum cross drafts, away from doors and windows, etc. when possible.
5, For best performance duct runs should be as short
and as straight as possible. Where turns are necessary, keep turning radius as large and as smooth as possible.
WARNING - TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
a) Never leave surface units unattended at high settings.
Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium settings.
b) Always turn hood ON when cooking at high heat
or when cooking flaming foods.
c) Clean ventilating fans frequently. Grease should
not be allowed to accumulate on fan or filter.
d) Always use cookware appropriate for the size of the
surface element.
