FOLLOW THESE GUIDELINES WHEN INSTALLING DUCT WORK:
- Your venting system must vent to the outdoors either horizontally through the back wall (13) or vertically through
the roof (14) (refer to Fig. 5/Fig. 6/Fig. 7).
- Use round metal duct work with a uniform diameter of 177 mm (7 in). The total duct run in the venting system
should not be more than 10.7 m (35 ft).
- Calculate the total effective length of the duct work by adding the equivalent lengths in the table shown (Fig. 9).
For each tting used add the length of the equivalent straight duct used in the system.
- Fasten all connections between pieces of duct with sheet metal screws and tape all joints with certied duct tape.
- If you must turn the path of the duct work using elbows, keep the number of elbows to a minimum for effective
performance and use no more than three 90° elbows. Ensure that there is a minimum of 458 mm (18 in) of
straight vent between each elbow. Elbow as far away from the range hood’s exhaust opening as possible.
- Cap the exterior of the duct with a wall cap (15) or roof cap (16). Never use 102 mm (4 in) laundry-type wall caps.
Use caulking to seal exterior wall or roof opening around the cap.
- The venting system must have a damper. If the roof or wall cap has a damper, do not use the damper supplied
with the range hood.

the risk of re.
The range hood should be cleaned (regularly internally and externally) to preserve its appearance and performance.
Do: Do Not:
- Always clean in the direction of the grain
(original
polish lines).
- Clean the range hood periodically with hot,
soapy water and a clean cotton cloth.
- Always rinse well with clean water two or
three times after cleaning. Wipe completely
dry with a soft non-abrasive cloth.
- After cleaning, you may polish with a non-
abrasive stainless steel polish or cleaner.
Always rub lightly and with the grain
- Ensure that the venting system is free of
debris, if you have one.
- Do not use corrosive or abrasive detergents,
steel wool, or scouring pads. These will scratch
and damage the stainless steel surface.
- Do not use any products containing chloride,
uoride, iodide, or bromide on this product, as
they will deteriorate the surface rapidly.
- Do not allow cleaning compounds, salt
solutions, disinfectants, or bleaches to remain
in contact with the product for extended
periods of time.
- Do not allow any deposits to remain for long
periods of time on the range hood. Rinse with
water immediately and wipe dry with a clean
cloth.
- Do not let plaster dust or any other
construction residue enter the hood. During
construction or renovation, cover the hood.
- Combustible products used for cleaning such
as acetone, alcohol, ether, or benzol are highly
explosive and should never be used close to a
range or stove.
FILTER
The lter tted by the factory is intended to lter out residue and grease from cooking. You do not need to replace them
on a regular basis, but you should keep them clean.
Do: Do Not:
- Clean the lter once a month using non-
abrasive detergents, either by hand or in the
dishwasher. When using a dishwasher, set
the dishwasher to a low temperature and a
short cycle setting. The lter may become
discoloured in a dishwasher, but this does
not affect its performance.
- Allow lters to completely dry before re-
installing them in the range hood.
- Do not allow oil to accumulate over
more than 80% of the lter surface. Oil
accumulations may drip oil onto the range.
- Do not wash charcoal lter. The charcoal
lter should be replaced when it is covered
in grease and has reached its maximum
absorbancy.

Troubleshooting
DANGER: Turn off the power circuit breaker or the power switch on the junction box before performing
maintenance. Touching circuitry inside the range hood while it is energized may result in serious injury or
death.
Problem Solution
The range hood does not operate.
- Check that the power supply cable and all electrical wiring are properly
connected.
- Check that the power is turned on at the junction box or circuit breaker.
- Check that the wiring between the switch control and the control board
are connected properly.
The range hood vibrates when the fan is
operating.
- Check that the range hood has been secured properly. Tighten into
position, if necessary.
- Check that the motor is secured in place. If not, then tighten the motor in
place.
- Check that the fan is not damaged. If so, replace the fan.
The fans seem weak.
- Check that the duct size used is at least 177 mm (7 in) round. The range
hood will not function efciently with insufcient duct size.
- Check that the duct is not clogged with debris and the tight mesh on the
wall cap, if applicable, isn’t restricting air ow.
- Check that the damper unit is opening properly.
- Check that no birds or animals have nested in the duct.
The lights work, but the fan is not spinning, is
stuck, or is rattling.
- The thermal protection system detects if the motor is too hot to operate
and shuts the motor down. In this case, the motor will function properly
after the thermal protection system cools down (after approximately
10 min).
- Check that the fan isn’t jammed or scraping the bottom.
- If nothing else works, the motor may be defective or seized. If so,
replace the motor.
The range hood is not venting properly.
- Check that no birds or animals have nested in the duct.
- Check that the distance between the cooktop and the bottom of the
range hood is between 458 mm (18 in) and 710 mm (28 in).
- Check that duct work follows all requirements.
Use round metal duct
work with a uniform diameter of 177 mm (7 in). The length of duct work
must not exceed
35 ft (10.7 m). Reduce the length of duct work and
