Installation, Operation and Maintenance Manual
Please read and save these instructions for future reference. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety information. Failure

Listed to UL Subject 300A
General Safety Information
Personnel should have a clear understanding of these
instructions and all applicable, current local and national
building and fire codes before installing this product.
NOTE
All service and maintenance on the fire suppression system
should be conducted by an authorized fire equipment
distributor. Do not tamper with fire suppression components
if not instructed to do so.
WARNING
To reduce the risk of fire, electric shock, or injury to
persons, observe the following:
• Use this product only in the manner intended by the manufacturer
(to cover domestic ranges used for domestic purposes).
• When cutting or drilling into wall or ceiling, do not damage
electrical wiring or other hidden utilities.
• Ducted exhaust fans must always be vented to the outdoors.
• Use only rigid, metal ductwork
• This unit must be properly grounded.
To reduce the risk of range top grease fire:
• Never leave the range unattended at high settings. Boil-overs
cause smoking and greasy spillovers that may ignite.
• Dense smoke from frying pans indicates cooking oil is near auto
ignition – turn the burner down or off.
• Always turn the hood fan ON when part of the cooking surface is
on
• Always make sure the hood grease filter is installed before cooking.
• Clean hood grease filter frequently. Do not allow grease to
accumulate on filter.
• Always use proper pan size. Use cookware appropriate for the size
of the surface element.
• Keep cooking areas clean and clear of combustible materials.
To reduce the risk of injury to persons in the event of a
range top grease fire, observe the following:*
• SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal
tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS.
If the flames do not go out immediately, EVACUATE AND CALL
THE FIRE DEPARTMENT.
• NEVER PICK UP A FLAMING PAN. You may be burned.
• DO NOT USE WATER, including wet dishcloths or towels - violent
steam explosion will result.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
AVERTISSEMENT
Pour réduire le risque d’incendie, de choc électrique ou
de blessure corporelle, respecter ce qui suit :
• Utiliser uniquement ce produit de la façon prévue par le fabricant
(pour couvrir les cuisinières domestiques utilisées à la maison).
• Lors de la découpe ou du perçage de murs ou plafonds, ne pas
endommager les câbles électriques et autres conduites masquées.
• Les caissons d’extraction à gaine d’évacuation doivent toujours
être évacués vers l’extérieur.
• Utiliser uniquement un réseau de gaine rigide, en métal.
• Cet appareil doit être bien raccordé à la terre.
Pour réduire le disque d’incendie de graisse sur le
dessus de la cuisinière :
• Ne jamais laisser la cuisinière sans surveillance à des réglages
élevés. Les débordements causent de la fumée et des
débordements de graisse qui peuvent s’enflammer.
• Une fumée dense provenant de poêles à frire indiquent que l’huile
à friture s’approche de son point d’inflammation spontanée. Régler
le bruleur plus bas ou l’éteindre.
• Toujours activer le ventilateur de la hotte lorsqu’une partie de la
surface de cuisson chauffe.
• Toujours s’assurer que le filtre de graisse de la hotte est installé
avant la cuisson.
• Nettoyer fréquemment la graisse du filtre de la hotte. Ne pas laisser
s’accumuler la graisse sur le filtre.
• Toujours utiliser la taille appropriée de poêle à frire. Utiliser une
batterie de cuisine proportionnelle à la surface de l’élément.
• Garder propre l’aire de cuisson et dégagée de toute matière
combustible.
Observer les points suivants pour réduire le risque
de blessures aux personnes advenant un incendie de
graisse sur le dessus de la cuisinière :*
• ÉTOUFFER LES FLAMMES à l’aide d’un couvercle ajusté,
d’une plaque à biscuits ou d’un plateau en métal, puis fermer le
brûleur. S’ASSURER D’ÉVITER DES BRÛLURES. Si les flammes
ne s’éteignent pas immédiatement, ÉVACUER LES LIEUX ET
APPELER LE SERVICE D’INCENDIE.
• NE JAMAIS SAISIR UNE POÊLE EN FLAMME. Vous pourriez vous
brûler.
• NE PAS UTILISER D’EAU, ni de linges à vaisselle ni de serviettes
mouillées car il pourrait se produire une violente explosion de
vapeur.

les incendies de cuisine) publiés par la NFPA

WARNING
Failure to affix the mounting bracket
to studs correctly can lead to
structural damage and/or serious
injury. The structural integrity of
the wall is the responsibility of the
contractor.
Hood Weight
30 inches 86 lbs.
36 inches 93 lbs.
AVERTISSEMENT
Si le support de fixation est mal posé
sur les montants, il peut y avoir des
dommages structuraux et/ou de
graves blessures. L’entrepreneur est
responsable de l’intégrité structurale
du mur.
It is recommended that before drywall is hung, all
electrical cables that need to be run within the wall
should be run through the wall to their corresponding
components. Mount the control j-box to line up with
the right corner of the hood mounting bracket and run
cables for these components into this box through the
grommets. Confirm all critical mounting points will need
to be secured through studs or utilize dry wall hangers.
Hood weight should be supported by at least two (2)
studs. Hood needs to be centered above the range and
within the height requirements shown. Make sure that
with integral fan – rear discharge configurations, the
studs and control j-box do not interfere with the rear
discharge duct.
After drywall is hung, affix mounting bracket to wall
using the necessary field provided fasteners through the
critical mounting points.

Ductwork (if applicable)
Running ductwork will be required for hoods configured for external fans. A small rectangular piece of duct spanning
the width of the wall will be required for integral fan – rear discharge configurations (discharging through the back
wall). Check the individual hood drawings to see what fan type is provided with your system.

All ductwork will need to be provided in the field. Installing ductwork must be done by qualified person(s) in
accordance with all applicable codes and standards, including fire-rated construction. All ductwork, per IMC Section
505 should be constructed of sheet metal, have smooth inner walls, be air tight, and be independent of all other
exhaust ductwork systems.
To minimize static pressure losses and promote adequate airflow, minimize duct run lengths where possible.
For external fan configurations, duct should be connected to the 8 inch collar adapter on the hood mounting bracket.
Transitions should be utilized to expand duct to duct size minimum requirements noted in table above.
Hood
1. Remove hood from crating. Remove the grease filter.
2. Carefully lift it onto the lower hood tabs on the wall mounting bracket.
2. While holding the hood up, hook the safety cable to the chain link on the mounting bracket and screw nut to close
the link. The hood is now in the service position.
3. To put the hood into operation position, lift the hood up, and one at a time re-hook the clamps and pull the clamps
tight until they lock. Make sure the safety bolt lever is located inside the notch in the hood mounting bracket. See
page 22 for pictures and more information.
4. When all construction is complete, remove protective plastic sheeting from hood stainless steel. Clean (using
alcohol and rag) and polish (using stainless steel polish) the hood. When cleaning or polishing, be sure to wipe
with the grain and not against it.
