- INSTALLING THE RANGE HOOD -
(Keep all packing materials for return or exchange)
Temporarily wire the hood to test for proper operation before installing.
Before installing, please peel protective film off the hood first, if any.
NOTE: The recommended distance from range hood bottom to top of the cooking surface is
between 28” ~ 30”.
{Fig. 1a} {Fig. 1b} {Fig. 1c}
WARNING: As the hood is heavy, we strongly recommend using all 8 mounting
holes to install the hood. Installation may require more than 1 person.
For Mounting on a Cabinet with a Flush Bottom
1) If you need to move the cooking range to work on the cabinet, turn off the power for an
electric range at the main electrical box. SHUT OFF THE GAS BEFORE MOVING AGAS
RANGE.
2) To make an electrical line access opening, please refer to section Electrical Power Line
Access.
3) Use 1” wood screws for mounting the hood. Puncture the eight indented mounting holes.
Measure & create access opening for electrical wires under the cabinet.
4)
a) For top venting: Cut rectangle opening required for 6”, 7” or 3¼” X 10” duct. Remove
temporary plastic vent cover on the top of the hood. Replace with the plastic multi duct
exhaust vent piece that came with the hood. Cut along the indented outline for the size of
the duct opening that you need. {Fig. 2} Fasten plastic multi duct exhaust vent piece
with the raised surface facing outward back onto the top of the hood. (See Fig 2)
7” 6” {Fig. 2} Multi Duct Exhaust Base (included)
(Remove) Temporary vent cover

b) For rear venting: Unscrew the rectangular plastic vent portion at the back of the hood.
{Fig.4} Turn the vent piece over so that the flat surface is facing you. Cut along the
indented outline until there is a 3¼” X 10” opening. Fasten plastic vent piece with the
raised surface facing outward back onto the hood.
{Fig.4} {Fig.5} {Fig.6}
( Rear Venting )
5) Remove bottom panel & carefully place aside.
6) Take the hood, place electrical power line through access opening {Fig. 1b}, and use eight 1”
wood screws for mounting the hood. {Fig.1e}. CAUTION: MAKE SURE THE HOOD IS
SECURE BEFORE RELEASING.
7) Replace bottom casing.
8) Slide each oval oil container into the oil container slots at the back of the safety screen.
{Fig.5}
9) Finally, place a round oil container with the three prongs into the larger holes in the specially
made openings in the center of the screen & turn clockwise until it snaps into place. Do the
same for the other round oil container. {Fig.6}
For Mounting on a Cabinet with a Recessed Bottom
1) If you need to move the cooking range to work on the cabinet, turn off the power for an
electric range at the main electrical box. SHUT OFF THE GAS BEFORE MOVING AGAS
RANGE.
2) Measure the space (under the cabinet) between the inside front edge and inside back edge
{Fig. 3}. With a saber saw, cut wood filler strips (not included) to fill in the bottom of the
cabinet. Use 2-1/4” long wood screws (not included) to attach wood strips to the cabinet.
Make sure you have wood filler strips for all eight mounting holes. For metal cabinet, use
3/8” x 2-1/2” bolts and nuts to secure the strips to the cabinet. The hood will mount on these
filler strips. (For a more secure installation, you can also use screws from inside the cabinet
down into the wood filler strips.) Make sure the filler strips do not cover the electrical power
line access opening.

- MAINTENANCE OF THE HOOD -
----SAFETY WARNING----
INTERIOR OF HOOD MAY HAVE VERY SHARP EDGES, PLEASE
WEAR PROTECTIVE GLOVES IF YOU HAVE TO OPEN THE
HOOD FOR CLEANING OR SERVICING.
Cleaning
To clean the hood surface, use only mild soap or detergent solutions. Dry up surfaces using soft
cloth. CAUTION: Never use abrasive cleaners, pads, or cloths.
If the hood looks splotchy (stainless steel hood), use an orange base cleaner to clean the surface
of the hood (make sure the cleaner does not get on any control switches). Spread a light coating
over the surface of the hood and leave on for a few minutes (do not leave on too long or there
might be damage to the hood finish). Use a soft towel to wipe off the cleaning solution, gently
rubbing any stubborn spots. Use a slightly damp towel to get rid of any cleaning solution. Use a
dry soft towel to dry the hood.
To bring the glow back into a stainless steel finish, use a stainless steel cleaner.
To clean hood fans, turn on high speed and spray a mild degreaser into the fans. Liquid residue
will accumulate in the oil containers located at the back of the safety screen. These slide easily
in and out for cleaning. The round transparent holders attached to the fan cover can be
unscrewed (turn counterclockwise) for cleaning. (To replace, just screw back in turning
clockwise until it clicks into place.) To clean the fan safety screen, remove the screw (leave in a
safe place), and slide safety screen out. Both oil containers and fan safety screen should be
washed with warm soapy water and completely dry before returning in place. (Both are top rack
dishwasher safe.)
CAUTION: Never put your hand into the area housing the fan while the fan is operating.
For the most efficient operation of your range hood, clean the range hood surface, fans and
optional filters regularly.
CAUTION: Drain oil holders before oil can overflow.
