The Importance of Cooking Ventilation
The main purpose of cooking ventilation is to capture the
by-products of cooking. These by-products are heat, steam,
smoke, odor, hazardous gases, and grease. Without proper
cooking ventilation, these by-products can cause a great deal
of harm to the home. Vent-A-Hood®range hoods exhaust
all cooking by-products to the outside with the exception of
GREASE, which is collected by the blower system.

Operating Instructions
A. Models with Halogen Lights
When using the hood, the user should generally start with the hood
on the low setting, and switch to the high setting as required.
Red Switch - This switch operates the two-speed motor. This two-
speed motor allows the user to switch the hood to “LOW” (position I)
for quieter operation during light cooking, while the “HIGH” (position
II) setting delivers the full power of the blower unit. If the two-speed
motor is turned to “LOW”, the heat sensor (SensaSource®) monitors
cooking activity. If the heat reaches an unacceptable level inside the
hood,orarangereoccurs,thetwo-speedmotorwillswitchfrom
“LOW” to full power automatically. The sensor will return the motor to
the “LOW” level when the heat subsides or the hood may be turned
off manually (middle position).
Red Switch
White Switch - This switch controls the lights. “LOW” level lighting
(position I) is 25 watts per bulb, “HIGH” level lighting (position II) is
50 watts per bulb. Off is in the middle position.

Hood Cleaning
A. Hood Canopy
Wipe down the interior and exterior of the hood as needed with a soft
cloth and warm soapy water (liquid dish detergent is acceptable). Do
not use acids, abrasives, strong detergents, solvents, or scouring
pads. Stainless steel should be treated with a quality stainless steel
cleaner such as Stainless Steel Magic®(Vent-A-Hood®part number
SS64). Follow all label instructions. Do not polish across the grain
or in circles.
B. Blower Unit
WARNING: To reduce the risk of personal injury, be sure the
power is turned off in the hood before removing the grease pan.
The blower captures grease by-products in the grease pan attached
to the bottom of the blower. Cooking habits determine how often the
grease pan will need to be cleaned.
To remove the grease pan, unsnap the suitcase latches (A) (one on
each side of the pan).

Hood Cleaning (Continued)
The grease pan (B) may now be lowered from the hood.
Clean the grease pan in a sink of warm, soapy water (liquid dish
detergent) and let soak for a few minutes. Wash with a sponge or
dishcloth, rinse and let drain. Reinstall the grease pan and snap
the suitcase latches in place. The grease pan alternatively may be
placed into a dishwasher.
C. Blower Wheel
WARNING: To reduce the risk of personal injury, be sure the
power is turned off in the hood before removing the grease pan.
Regular cleaning of the grease pan should prevent grease
accumulation on the blower wheel. If grease build-up should occur,
the blower wheel may easily be cleaned in place using a soft bristle
toothbrush and a common degreaser such as Formula 409®. Take
carenottomoveorlosethemetalbalancingclipsthatmaybeafxed
to the wheel.
In instances where the blower wheel may need to be removed, follow
the instructions on the next page.

Hood Cleaning (Continued)
A soft bristle toothbrush with warm soapy water may be used to
clean the blades, or soak the blower wheel in warm soapy water.
When reinstalling the wheel onto the motor shaft, make sure the set
screwmakesdirectcontactwiththe“atspot”onthemotorshaft.
Slide the blower wheel onto the motor shaft as far as it will go and
tighten the set screw (clockwise) to lock the blower wheel in the
correct position.
Remove the grease pan as described in Hood Cleaning, Section
B. If the blower wheel needs to be removed, a 1/8” T-handle hex
wrench is necessary. A T-handle hex wrench (A) may be obtained
from Vent-A-Hood®to accomplish this (Vent-A-Hood®part number
AW101). There is a small set screw on the side of the hub of the
wheelthattightensupagainsta“at”spotonthemotorshaft.Theset
screw must be turned ½turn counterclockwise to remove the blower
wheel. Insert the T-handle allen wrench through the guide hole (B)
located next to the blower housing latch, through the blades of the
blower wheel, and into the set screw. Use caution to avoid bending
or distorting the blower wheel and take care not to move or lose the
metalbalancingclipsthatmaybeafxedtothewheel.Ifthewheel
isdifculttoremove,theareawherethemotorshaftmakescontact
with the blower wheel hub may need to be sprayed with a common
penetrating oil such as WD-40®.

A. Light Bulb Replacement
WARNING: To reduce the risk of personal injury, turn off power
and allow lights to cool before proceeding.
Toremovethebulb,turnitcounterclockwise.Ifthelightisdifcultto
remove, it may be necessary to use the light bulb suction cup that
has been provided with this manual.
Replace the bulb with a GU10 120 volt, 50 watt halogen bulb (Vent-
A-Hood®part number P1110).
Maintenance/Troubleshooting
B What To Do If...
Smoke is in the kitchen. Check the following:
Is the hood sized appropriately for the type of cooking equipment
it is ventilating?
The purpose of a hood is to collect cooking contaminants and hold
them until the blower unit can exhaust them to the outside. Therefore,
it is necessary to size the hood based on the type of cooking
equipment that is being used. Whenever possible, hoods should
overlap the cooking equipment by at least three inches on each
side. The hood should also project out to the front edge of the front
burners. Finally, the height of the hood can affect its performance.
Generally speaking, taller hoods are more suitable for professional
style ranges, whereas under cabinet hoods are recommended for
standard cooking equipment.

Page 10L022
Maintenance/Troubleshooting (Continued)
Does the blower capacity of the hood match the cooking
equipment it is over?
K250 Single Blower (250 CFM) - For standard electric or small gas
cooking equipment.
Is the hood ducted properly?
Theductshouldbesmoothwalled.Corrugatedor“ex”typeduct
mustnotbeusedasitrestrictsairow.Theductworkshouldbethe
same square inch area (or larger) as the hood discharge for the
entire length of the duct run. Run the duct as short and straight as
possible. Enlarge the duct for longer duct runs. Maintain 4 to 5 foot
spacing between turns. Turns should be smooth and gradual, not
sharp and angled. Roof jack and wall louver openings must be free
of obstacles, at least as large as the duct size, and open freely.
Is the hood mounted at the appropriate height off of the cooking
surface?
The height of the hood off the cooking surface is very important. The
higher the hood is mounted, the less effective it will be. Hoods only
collect cooking vapors; they will not pull cooking contaminants back
into the hood if they escape unto the kitchen. Generally speaking,
the deeper the hood, the higher the hood can hang and still be
effective.

Standard Liner - KHSLD 21-24"

Page 11 L022
Maintenance/Troubleshooting (Continued)
Does the damper open and close freely?
With the grease pan removed (see Hood Cleaning, Section B), locate
thedamper(ap) andensurethatitopensandclosesfreely.Ifit
does not, identify and remove any obstructions that are preventing
the damper from opening. Screws protruding through the duct work
are the most common obstruction. During installation, only duct tape
should be used to connect duct work to the top of the hood. Screws
that are used to connect duct work and transitions extend inside the
duct work and may obstruct the damper from opening.
Is the hood making a rubbing or scraping noise?
This may be caused by the blower wheel coming in contact with the
blower housing. Refer to Hood Cleaning, Section C for blower wheel
installation details.
NOTE: If smoke still enters the kitchen after following these
suggestions, contact your dealer for additional service and/or
suggestions.
