Skill Level – Installation of this vent hood requires basic mechanical and

electrical skills.

Proper installation is the responsibility of the installer.

CAUTION:

Due to the weight and size of these vent hoods and to reduce the

risk of personal injury or dam-age to the product, TWO PEOPLE

ARE REQUIRED FOR PROPER INSTALLATION.

Sufficient air is needed for proper combustion and exhausting of gases 

through the chimney of fuel burning equipment to prevent back- 

drafting. 

Follow the cooking equipment manufacturers guideline and safety 

standards such as those published by the National Fire Protection 

Association (NFPA), the American Society for Heating, Refrigeration 

and Air Conditioning Engineers (ASHRAE), and local code. 

When cutting or drilling into wall or ceiling, do not damage electrical 

wiring and other hidden utilities. Ducted systems must always be 

vented outdoors.

WARNING

:

To reduce the risk of the fire or electrical shock, do not use this range 

hood with any external solid-state speed control device. Any such 

alteration from original factory wiring could result in damage to the unit 

and/or create an electrical safety hazard. TO REDUCE THE RISK OF 

THE FIRE, USE ONLY METAL DUCTWORK. These vent hoods are 

designed to be installed onto a wall or beneath a cabinet.

PRE-INSTALLATION INSTRUCTIONS

Please read the instructions carefully. Unpack the Range Hood and check that all 
functions are working before installing.

Ensure that the voltage (V) and the frequency (Hz) indicated on the sticker match 
the voltage and frequency at the installation site.

Check that the area behind the installation surface to be drilled is clear of any 

electrical cables or pipes, etc.

The stainless steel surfaces of the Range Hood are very easily damaged during 
installation if scratched or bumped by tools. Please take care to protect the 
surfaces during installation.

Protect the cooktop surface below with cardboard, or the like, to prevent 
damage occurring during installation.
The manufacturer shall not be held liable for consumer’s failure to observe and 
follow all pre-installation procedures and safety regulations.

The vertical distance from the cooking surface to the bottom of the range hood 
should be at least 24 in. to 36 in. for best performance.

Determine if your installation will be top venting or back venting, and ensure 
that the openings in the cabinet or wall are in the appropriate locations and 
appropriate size.
If this is a new installation, choose the venting method that suits your needs. Cut 
out openings for the damper and for power access in the cabinet bottom or 
exterior wall, depending on the installation method chosen.

DUCTWORK PLANNING

These vent hoods are equipped for 8" round ductwork. This hood may be vented

vertically through upper cabinet or ceiling. A duct transition piece is supplied for

vertical exhaust. You may use elbows (sold separately) to vent horizontally

through the rear wall.
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 12.5 feet. equivalent length for any duct

configurations.

Use metal ductwork only.

WALL FRAMING FOR ADEQUATE SUPPORT

These vent hoods are heavy. Adequate structural support must be provided.

* Actual length of straight duct plus duct fitting must equivalent. Equivalent

lengths of duct pieces are based on actual tests conducted by Evaluation
Engineering and reflect requirements for good venting performance with any
ventilation hood.

IMPORTANT:

Plug the Unit in and Test all Functions Before Installing.
