These vent hoods must be installed 30" min. to 36" max.  
above the cooking surface. Exact installation height is  
determined by ceiling height. The cooking surface  
should be at least 36” above the floor.

IMPORTANT: Clearances may vary due to type of  
cooking product and local codes. Check with local  
inspectors to be sure standard is applicable.  
• When installing these Island Hoods above a  
Monogram Professional Range or Cooktop,  
installation clearance must be at least 30".  
These accessories include telescoping support  
frames and decorative covers. Order the accessory  
for your model at the same time as the vent hood and

Ductwork Planning  
IMPORTANT - (Please read carefully)  
• These vent hoods are equipped for 10” round  
ductwork.  
WARNING:  
MUST BE PROPERLY GROUNDED.  
• Determine the exact location of the vent hood.  
• Plan the route for venting exhaust to the outdoors.  
• Use the shortest and straightest duct route possible.  
For satisfactory performance, duct run should not  
exceed 150 ft. equivalent length for any duct  
configurations.  
• Refer to “Duct Fittings” chart to compute the  
maximum permissible length for duct runs to the  
outdoors.  
FOR PERSONAL SAFETY, THIS APPLIANCE  
ATTENTION –  
POUR DES  
RAISONS DE SÉCURITÉ, CET APPAREIL  
DOIT ÊTRE CORRECTEMENT MIS À LA TERRE.  
Remove house fuse or open circuit breaker before  
beginning installation.  
• Use rigid metal ductwork only.  
• Install a roof cap with damper at the exterior opening.  
Order the cap and any transitions needed in advance.  
Do not use an extension cord or adapter plug with  
this appliance. Follow National Electrical Code or  
prevailing local codes and ordinances.  
Ceiling Framing for Adequate Support  
• These vent hoods are heavy. Adequate structural  
support must be provided. The ceiling structure must  
be capable of supporting the weight of the hood and  
any inadvertent user contact loads (approximately 300  
pounds). The hood support frame will be supported by  
2 x 4 cross framing.  
Electrical Supply  
This vent hood must be supplied with 120V, 60Hz,  
and connected to an individual, properly grounded  
branch circuit, and protected by a 15 or 20 amp  
circuit breaker or time delay fuse.  
• Wiring must be 2 wire with ground.  
• If the electrical supply does not meet the above  
requirements, call a licensed electrician before  
proceeding.  
• Route house wiring in the ceiling, as close to the  
installation location as possible. Allow additional  
length from ceiling joists to reach the junction box  
on the bottom of the hood support frame.  
• Connect the wiring to the house wiring in accordance  
with local codes.  
Accessory Frames and Duct Covers  
• All models are shipped with a support frame and duct  
covers for ceilings heights of 7’11" to 8’5".  
• Optional accessories include telescoping support  
frames and duct covers to reach 8’6” and up to  
10’4” ceiling heights.  
• Optional accessories must be ordered with the hood  
and be on site before final framing and wall finishing.  
Grounding Instructions  
The grounding conductor must be connected to  
a ground metal, permanent wiring system, or an  
equipment-grounding terminal or lead on the hood.  
Mounting the hood without a support frame  
The distance between the cooking surface and the  
bottom of the hood must be 30" to 36". In situations  
where the ceiling is low, the hoods may be secured  
directly to the ceiling without the supplied frame.  
Use the bottom of the supplied support frame as a  
template to locate the mounting holes in the top of the  
hood. Use shims on the ceiling joists or cross framing  
in the mounting hole locations. This will allow the  
mounting screws to engage the recessed keyhole  
slots in the top of the hood. See Step 2.  
WARNING:  
The improper  
connection of equipment-grounding  
conductor can result in a risk of electric shock. Check  
with a qualified electrician or service representative if  
you are in doubt whether the appliance is properly  
grounded.  
AVERTISSEMENT  
Le mauvais branchement du fil de mise  
à la terre peut causer un choc électrique. En cas  
de doute, consulter un électricien qualifié ou un  
technicien pour déterminer si l’appareil est à la terre.

Use a plumb bob to check the location. The  
countertop/cooktop below the hood must be centered  
with the hood.  
The hood should extend beyond the front and rear edge  
of the cooking appliance.  
The duct in the ceiling must be centered over the

Installation Instructions  
STEP 15 INSTALLATION CHECKLIST  
Check Blower Safety Screw  
Check appearance and installation  
Use a spirit level to check that the hood is level.  
Review installation instructions to determine source  
of problem.  
Ensure that blower safety screw is securely tightened.  
See page 16, Step 9. If screw is missing, order  
replacement parts bag.  
Top covers (if used) should lay flat in the recess on  
top of the hood. Make sure side tabs are engaged in  
slots and the cover is secured with two screws.  
Check Operating Sound and Proper Air-Flow  
Turn blower to each speed setting and listen for rattles  
and vibration. You should notice an audible difference  
at each speed setting.  
Clean the hood surfaces and all filters. See the  
Owners Manual for cleaning instructions. They  
should be free of construction debris such as  
sawdust.  
Check for foreign material in transition.  
Check that blower screen is not damaged or pushed  
into the blower impeller.  
The damper should move freely. Listen for opening and  
closing while turning the unit on and off.  
Check that the damper is not damaged, does not  
vibrate and that damper bumper pads are in place.  
Order a damper replacement assembly if needed.  
Check that ductwork is 10" round. If duct type is not  
rigid and less than 10" round, inform the consumer that  
performance will be reduced.  
Check Lighting Function  
Check that power cable is plugged into the junction  
box on top of the hood.  
Turn halogen lamps to each setting. Note change in  
brightness at different settings.  
Check that each lamp bezel is secure. Turn to the right  
to tighten. Order replacement lamp bezel and socket  
assemblies if needed.
