Read this instruction completely before starting installation. Planning the complete installation before starting any work is
highly recommended. This includes all aspects of the installation including hood location, ducting, electrical requirements, and
adequacy of mounting surfaces.
TABLE - 1
Model LOHI = Internal ventilator
Model LOHE = Remote ventilator
This hood series has been designed to be used with the ventilators shown in Table –1. Before
cutting into cabinets, it is necessary to confirm that the correct ventilator is being used. Your
dealer should have reviewed your needs prior to your purchase. Be sure you have the correct
ventilation system.
CAUTION: To Reduce The Risk Of Fire And Electrical Shock, Install This
Rangehood Only With Blowers Manufactured By Lynx Professional Grills.
DUCTING: Use a minimum 10" round duct for LOHI and LOHE installations. See Page –3. A standard starting transition
(33895) is included with the Hood.
SAFTY WARNING:
Turn off power circuit at the service entrance and lockout panel before wiring the range hood.
NOTE: Unit must be vented
to the outside of the building.

BEFORE STARTING INSTALLATION, YOU MUST IDENTIFY THE VENTILATOR MODEL BEING USED AND
IF A TOP OR REAR EXHAUST IS TO BE USED.
Prepare cabinet and/or wall for mounting either top (Fig - 1)
or rear (Fig 6 & 7) exhaust. Use furring strips to level cabinet
mounting surface with any cabinet trims.
For knock out removal see Fig- B

Break the metal webs by placing a screwdriver at one corner
of the plate and hitting screwdriver sharply with a hammer.
After breaking a second web the plate can be flexed to break
other webs.
Wear eye protection when using tools.
Caution: When knock outs are removed the edges willbe
sharp! Sharp Edges should be Filed or Covered with
Metal Tape.
Attach and secure the transition to the hood with #6x3/8 sheet
metal screws and tape all joints prior to installing the hood.
Attach hood to cabinet using #10 wood screws. Holes are
located in the back panel and top panel of the hood for
mounting. Use a minimum of four #10x3/4 wood screws to
mount the hood. Longer screws are required if wall board or
other nonstructural surfaces are used between the hood and
main mounting surface which should be a minimum of 3/4”
thick. When using rear holes for additional mounting use
appropriate anchors if not engaging the wood structure.
HINT: If you find vibration noise is present because of
cabinet structure use additional screws, in holes available, to
make the mounting more ridged.
Connect 120 volt, 60 Hz power through the conduit hole in
top of hood, connecting to pigtail in hood junction box, white
to white, black to black and connect green ground wire to the
power supply ground wire per local codes. See Fig –A.
NOTE: Recommended height over BBQ Grills = 36
inches.
Hood is recommended for use over domestic gas or electric
appliances. Not recommended for use over solid fuel fired
appliances.
After installing the hood, install the internal blower (Top
Exhaust See Fig 2; Rear Exhaust See Fig - 4) unit by
positioning the blower onto bracket-A, notched blower
bracket will center blower. Rotate into position against hood
and secure Bracket –B to Hood with #8 sheet metal screws.
If the remote ventilator is used see related instructions. The
LOHE ventilator will require revision of some wiring in the
hood receptacle box - See LOHE instructions.
NOTE: LOHE requires a dedicated 20 AMP Power
Supply. All other ventilators require a dedicated
15 AMP Power Supply
CAUTION: The hood is of sufficient weight that two
installers are recommended to prevent injury or damage to the
hood in handling.

Outside Patio or Lanai Installation
Construction methods and installation shall comply with all local building codes. Internal
ducting shall be sealed using outdoor rated metal duct tape.
The LYNX hood with stainless steel canopy is approved for installation in an outside patio or lanai area if the area
is covered with a protective roof over the hood (wall style hoods are to be also mounted to a solid protective rear
wall) and installed with a GFCI protected branch circuit. Roof or Wall Caps are to be sealed to prevent moisture
migration to structure interior; use an outdoor rated sealant suitable for adhesion to the installation materials. See
Fig-8 for rear exhaust installation and Fig-9 for top exhaust installation.

Side View
See Fig –10 for structure with elevated roof/ceiling.
The Roof shall cover the top of the hood and extend a minimum of 42” from each side of the hood and 30”
minimum from the outer most edges of the hood front.
Since, outdoor areas are subject to strong cross drafts it is recommended that the hood extend at least 3 –inches, and
preferably 6 –inches, over either side of the cooking area to maximize the cooking discharge capture area. Cross
drafts will affect the efficiency of the ventilation system and cooking discharge can escape capture by the
hood/ventilation system. Be sure to plan for adequate ventilator (blower) capacity to minimize cross drafts
influencing the removal of cooking discharges.

Page 5 of 8 P/N 11857.00 Rev A
The installation instruction that accompanies the hood shall be followed to ensure all safety Instructions and
guidelines are adhered to. NOTE: Hood is recommended for use over domestic gas or electric appliances. Not
recommended for use over solid fuel fired appliances. See Fig-10 for soffit construction
