3.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and
other hidden utilities.
4.
Ducted fans must always be vented to the outdoors.
ALL WALL AND FLOOR OPENINGS WHERE THE RANGEHOOD IS INSTALLED MUST
This rangehood requires at least 24" of clearance between the bottom of the rangehood
and the cooking surface or countertop. This hood has been approved by UL at this distance from
the cooktop. Overhead cabinets on both sides of this unit must be a minimum of 18" above the
cooking surface or countertop. Consult the cooktop or range installation instructions given by
the manufacturer before making any cutouts. MOBILE HOME INSTALLATION The installation
of this rangehood must conform to the Manufactured Home Construction and Safety Standards,
Title 24 CFR, Part 3280 (formerly Federal Standard for Mobile Home Construction and Safety, Title
24, HUD, Part 280). See Electrical Requirements.
Determine which venting method is best for your application. Ductwork can extend either through the
wall or the roof.
The length of the ductwork and the number of elbows should be kept to a minimum to provide efficient
performance. The size of the ductwork should be uniform. Do not install two elbows together. Use
duct tape to seal all joints in the ductwork system. Use caulking to seal exterior wall or floor opening
around the cap.
Flexible ductwork is not recommended. Flexible ductwork creates back pressure and air turbulence
that greatly reduces performance.
Make sure there is proper clearance within the wall or floor for exhaust duct before making cutouts.
Do not cut a joist or stud unless absolutely necessary. If a joist or stud must be cut, then a supporting
frame must be constructed.
WARNING - To Reduce The Risk Of Fire, Use Only Metal Ductwork.
CAUTION - To reduce risk of fire and to properly exhaust air, be sure to duct air outside – Do
not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces, or garages.
Cold Weather installations
An additional back draft damper should be installed to minimize backward cold air flow and a
nonmetallic thermal break should be installed to minimize conduction of outside temperatures as
part of the vent system. The damper should be on the cold air side of the thermal break. The break
should be as close as possible to where the vent system enters the heated portion of the house.
!
• Venting system MUST terminate outside the home.
• DO NOT terminate the ductwork in an attic or other enclosed space.
• DO NOT use 4" laundry-type wall caps.
• Flexible-type ductwork is not recommended.
• DO NOT obstruct the flow of combustion and ventilation air.
• Failure to follow venting requirements may result in a fire.
BE SEALED.
