IMPORTANT SAFETY INSTRUCTIONS

WARNING: If the information in this manual is not followed exactly, a fire or explosion may result causing property damage, personal injury, or death.

  • Before beginning installation, please read and follow these important instructions for the safety of your home and the people living in it.
  • The instructions in this manual are intended for qualified installers and certified service technicians. Installation and electrical wiring must be completed by qualified professionals and by applicable codes and standards.
  • DO NOT attempt to install this appliance yourself. Injury could result from installing the unit due to a lack of appropriate electrical and technical background.
  • The installer should leave these instructions with the consumer who should retain for local inspectors’ use and future reference.
  • Due to the size and weight of ZLINE range hoods, a two-person installation is highly recommended.
  • Use care when handling the range hood, chimney cover, baffle filters, and any parts or accessories, as sharp edges may lead to injury. The use of gloves during installation is highly recommended.
  • The manufacturer will not be responsible for any damage to property or persons caused by incorrect installation, improper use of the appliance, or failure to heed the warnings listed.
  • The manufacturer reserves the right to make changes to its products when considered necessary and useful, without affecting the essential safety and operating characteristics.
  • This appliance is designed for general ventilating use only. DO NOT use to exhaust hazardous or explosive materials and vapours.
  • The combustion airflow needed for the safe operation of fuel-burning equipment may be affected by this unit’s operation.
  • Follow heating equipment guidelines and safety standards such as those published by the National Fire Protection Association (NFPA), American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and local code and government authorities.
  • Sufficient air is needed for proper combustion and exhausting of gases through the ducting installed with range hoods to prevent back drafting.
  • Before servicing or cleaning the unit, fully disconnect the hood from power to avoid the risk of electric shock and injury.
  • Ducted range hoods MUST ALWAYS be vented to the outdoors or in some instances converted to recirculate the air. All ZLINE hoods come with a transition piece with a built-in damper.
  • Some existing installations may already have an external damper at the exit point of the home. In this case, the damper in the transition piece of your hood needs to be removed, as these two dampers work against each other and will reduce the performance of the hood.
  • Please consult an HVAC or installation professional for advice to comply with local regulations and ensure appropriate ventilation.
  • When cutting or drilling into a wall or ceiling, be careful not to damage electrical wiring or other hidden utilities.
  • All electrical wiring must be properly installed, insulated, and grounded. ZLINE range hoods come with a grounded 3-prong plug that must be plugged into a dedicated 15-amp circuit. Manipulating the plug or cutting the electrical cord will void your warranty.
  • Electrical installation must be by the National Electrical Code ANSI/ NPA70-latest edition and/or local codes.
  • Old ductwork should be cleaned or replaced, if necessary, to avoid the possibility of a grease fire or other hazards. Check all joints on ductwork to ensure proper connection; all joints should be properly taped/secured.
  • When a range hood ventilates air out of the room, the vented air must be replaced; this is called makeup air. If a makeup air system is needed, but not used, a hood may not function as expected due to negative air pressure.
  • ZLINE does not currently provide makeup air units. Always consult applicable building codes regarding minimum and maximum airflow rates. Certain states may require additional items such as makeup air for larger CFM range hoods.
  • Keep the motor, fans, baffle channels, filters, tunnels, grease cups, and grease-laden surfaces clean. Grease should not be allowed to accumulate inside or on the surface of the range hood; clean surfaces frequently.
  • Take care when cleaning the range hood in spray form: never directly spray water or cleaners onto the electrical wiring, motor, button panel, or light bulbs.
  • After installation, use a stainless steel cleaning product or wipe to eliminate any residues from the protective film after removal.
  • When cleaning stainless steel, only use a stainless steel cleaner product with a soft sponge, or use a cloth with a warm soap and water solution. Never use abrasive powders or liquids.
  • To reduce the risk of fire and to disperse air properly, make sure to vent air outside. DO NOT vent exhaust into spaces between walls, crawl spaces, ceilings, attics, basements, or garages.
  • All ZLINE range hoods are ETL-listed, ensuring all parts are tested for safety and meet industry standards and regulations.
  • You must purchase appropriate flexible ducting and any additional items to vent the hood by government codes.
  • Please verify with local and state regulations on the proper venting method for your hood. Many agencies have CFM rating specifications for your hood.
  • Always turn the range hood on when cooking at high heat or when cooking flaming foods. Use high settings on the cooking range below only when necessary.
  • Never leave range top surface units underneath a range hood unattended at high settings. Boilovers can cause smoking and greasy spillovers that may ignite. Heat oils slowly in low or medium settings.
  • Always use appropriate cookware and utensils; always use cookware appropriate for the size of the surface element on your range top underneath a range hood.
  • To reduce the risk of injury in the event of a range top grease fire, smother flames with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. Never pick up a flaming pan — you may be severely burned.
  • Keep flammable or combustible material away from flames. If flames do not go out immediately, evacuate and call the fire department. DO NOT use water, including wet dishcloths or towels — a violent steam explosion will result.
  • Carefully inspect all items for damages upon delivery. Upon acceptance of the range hood, the owner assumes responsibility for its safe arrival.
  • Before installing your unit, test the range hood for proper functionality by plugging it into an appropriate outlet and testing the fan and lights. Do not install any appliance if they have missing or broken parts. If units arrive damaged, contact ZLINE Customer Service at 1-614-777-5004 for help.

BEFORE INSTALLATION

RANGE HOOD MEASUREMENTS

  • Hood MeasurementsZLINE-RK520-Ductless-Under-Cabinet-Range-Hood-FIG-1 \(2\)

NOTE: The recommended height to install your hood is 30″ (762 mm) minimum and 36″ (914 mm) maximum above your range top or cooktop. For outdoor installation, the hood should be installed between 36″ (914 mm) and 42″ (1067 mm) above the grill. These instances allow for optimal venting efficiency. Consult an HVAC or installation professional for ventilation advice.

RECIRCULATING KIT
NOTE: If you purchased a ZLINE under cabinet range hood with a recirculation kit, follow the instructions below before preparing to install the hood. If your range hood is not a recirculating model, please skip to Installation, page 7.

  1. Open the recirculating kit package and locate all necessary hardware. Included should be 4 screws with 4 washers.
  2. Line up the recirculating kit with the top-of-the-range hood as shown below.
  3. Secure the recirculating kit to the range hood with the provided screws and washers as shown below. Once secure, fully tightening each screw until the recirculating kit is flush with the range hood. Use care to not overtighten.
  4. Once secure, install the range hood as outlined on page 7.

DUCTING REQUIREMENTS

  • For non-recirculating hoods, determine the location of the venting pipe from the hood to the outside of your home before installation.
  • Ducting is not provided with your ZLINE range hood. It’s recommended to use solid ducting made of galvanized steel or another appropriate rigid metal ducting whenever possible for the lowest noise and highest flow.
  • Use a maximum of 40′ (12192 mm) of ductwork. Try to minimize the use of elbows.
  • You must establish a minimum of 12″ (305 mm) of vertical airflow from the top of the hood before executing any 90° turn. No more than 3 elbows are allowed; each 90° turn you make equates to 5′ (1524 mm) lost when accounting for the maximum 40′ (12192 mm).
  • Do not use any reducers on ducting smaller than the appropriate diameter for your hood’s transition piece (6″ or 8″ — 152 mm to 203 mm).
  • Any existing or additional dampers should be inspected for proper operation.
  • Always consult an HVAC or installation professional to determine the best ducting option for your range hood, as each kitchen and home layout will vary.

EXAMPLES OF PROPER AND IMPROPER DUCTING:

INSTALLATION

NOTE: The following instructions are for installing an under-cabinet hood into the wall above your cooktop. Depending on the size and model of your hood, units may have one or two mounting brackets, and each bracket may have one or more mounting holes; consult an installation professional, as each kitchen and home layout will vary.

  1. Measure the distance between the range top and the bottom of the range hood. A distance of 30″ to 36″ (762 mm to 914 mm) is recommended for optimal ventilation.
  2. Attach mounting brackets to the back of the hood using the provided screws, as outlined in the image below. Bracket(s) will differ in size and placement depending on the model of your range hood.
  3. Using a second person, hoist the hood to the wall to determine its final resting place. Use a pencil to mark drill holes through the brackets; use a level as needed.
  4. Set the hood aside and prepare to drill holes into your wall. Be sure to mount to a secure backing to hold the weight of the hood. If not drilling into studs, use plastic anchors to ensure a secure backing. Use a level to ensure a flush installation.
  5. After holes are drilled and anchors are inserted, secure the provided screws into the wall. Do not fully tighten the screws; leave roughly 1/8″ space of wiggle room.
  6. Secure the ducting transition piece to the top of the range hood using the provided screws, as outlined in the image below. NOTE: Some models may come with the transition piece already secured.
  7. Secure your ducting connection to the transition piece using foil-backed tape to hold it into place on top of the hood. Try and minimize the use of elbows; more elbows and longer runs create higher static pressure.
  8. The hood comes with a grounded 3-prong plug that must be plugged into a dedicated 15-amp circuit. Draw the electrical wire through the top of the hood and into the cabinet access opening above, as shown in the image below.
  9. Use a second person to hold the hood in place while you align the hood-mounting brackets to the partially fastened screws on the wall.
  10. Fully secure the mounting screws through the mounting brackets into the wall.
    • Scan for an under-cabinet hood installation tutorial video. Please note that depending on the model of the range hood, some installation processes may vary.

ALTERNATIVE INSTALLATION NOTES:

  • For recirculating units, or if you wish to install the under-cabinet range hood directly into the bottom of a cabinet, you’ll need to use a hammer and flathead screwdriver to knock out the mounting holes located on the left and right sides of the top of the hood.
  • Using a second person to hold the hood in place, secure the hood to the bottom of the cabinet using the provided hardware.
  • For cabinets with recessed bottoms, you’ll need to attach 4″ (102 mm) wide wood filler strips (not provided) on each side of the cabinet in order to line up with the mounting holes on the top of the hood.

REAR DUCTING CONVERSION

If you need to convert your hood to duct from the rear, follow these instructions.
NOTE: Converting the hood to rear-ducting is a modification of the standard hood and part of the installation process. It is recommended the hood is inspected before this procedure. Only certain models allow for rear ducting. Contact ZLINE at 1-614-777-5004 for information on compatible models.

  1. First remove the screws from the stainless steel panel. The small screws attach the panel to the range hood while the larger screws attach the panel to the motor.
  2. Remove the panel from the hood. The motor is attached to the panel. Do not disconnect the motor from the panel. The image to the right shows an example of the motor orientation.
  3. Remove the motor from the range hood. Be careful not to pull and disconnect the attached wiring.
  4. Rotate the motor so that the opening is facing out the rear of the range hood.
  5. Replace the panel so that the opening aligns with the opening of the blower/motor.

FAQs

NOTE: Some of these questions are specific to certain types of ZLINE range hoods and as such may not apply to some models.

  • Are ZLINE range hoods considered type 1 or type 2?
    • Type 1 — these types of range hoods are used with ranges, range tops, and appliances that produce grease and smoke.
  • Why is my range hood white?
    • This is a protective layer that is placed on all ZLINE range hoods to prevent shipping damage. This should be easily removable by peeling off.
  • Why are my range hood baffle filters blue?
    • This is a protective layer that is placed on certain ZLINE range hood model baffle filters to prevent shipping damage. This should be easily removable by peeling off.
  • What size hood should I choose for CFM (Cubic Feet Per Minute) purposes?
1. You must determine the output of the cooktop burners of your range; this is measured in British Thermal Units (BTUs).
2. You should provide 100 CFM of airflow per linear foot of range. To determine this, divide the BTU rating of your range by 100. This will give you the CFM rating needed for your range hood. For example: If your range is 35,000 BTUs, your range hood should have a rating of 350 CFMs or greater.
3. To determine the size of the range hood for satisfactory capture of fumes and gases, it’s recommended to go at least one size larger than the width of your range, or 3″ to 6″ (76 mm to 152 mm) wider. At a minimum, the hood should be the same size of your range. Additionally, the range hood width should cover 100% of the back burners and 50% of the front burners.
  • How loud is the range hood?
    • A sone is a measure of loudness — the higher the sone rating, the louder the sound of the hood. The sound of 1 sone is comparable to that of a quiet refrigerator. Keep in mind that other factors such as the size of the blowers can affect the loudness of the range hood. The higher the CFM, the louder the Sone rating will be.
  • Can my hood be ductless?
    • It is better to duct your range hood to the outside, but if this is not possible, ductless/ recirculating is an acceptable alternative. Many ZLINE range hoods can be converted to ductless.
    • Ductless is when the air circulates through charcoal filters to remove odours, grease, smoke, etc.
    • The clean air is then re-circulated back into your home.
    • Charcoal filters are not reusable and need to be replaced every six months or sooner, depending on cooking style and frequency.
  • What type of stainless steel are ZLINE hoods made of?
    • ZLINE indoor stainless steel range hoods are made with 430-grade stainless steel. ZLINE outdoor hoods are made of 304-grade stainless steel. The 304 grade is stronger and more resistant to rust and corrosion.
  • How many amps are produced on the highest fan setting?
    • For dual motors, up to 3.317 amps are produced. For single motors, it is 1.678 amps.
  • What type of motor is inside a range hood?
    • ZLINE hoods are equipped with a squirrel-cage motor.
  • Is the width of my range hoods description, the actual size?
    • No — the actual width of the range hood will be slightly less than the generic description of the range hood to better-fit cabinet cutouts. For instance, a 30″ (762 mm) range hood will measure 29 1/2″ (749 mm).
  • How do I clean my baffle filters and how often?
    • Your baffle filters should be washed with hot water and soap once per month or placed in a dishwasher for cleaning. Make sure filters are completely dry before reinstalling. Replace the filters if they become damaged or too dirty to clean.
  • Can I clean my charcoal filter?
    • No — charcoal odour filters cannot be washed and must be discarded and replaced when they become noticeably dirty and/or have stopped filtering the odours. They should be replaced at least every six months.

TROUBLESHOOTING

  • What is the best way to duct my range hood?
    • For maximum performance, match your duct size to the original size of the fan’s ducting.
    • Use the shortest amount of ducting and keep it as straight as possible. Do not exceed 40′ (12192 mm) of ducting. For every 90° elbow, deduct 5′ (1524 mm) from the total.
  • Do I have to exhaust the range hood to the outdoors?
    • Yes. If installing a range hood that has ductwork connected to it (any hoods that do NOT recirculate the air back into the room), to properly exhaust the air, be sure to duct the air outside.
    • DO NOT vent exhaust air back into the spaces within the walls, ceilings, attics, crawl spaces, or garages. A buildup of humidity and grease could cause damage and/or a fire risk to your home.
ISSUE POSSIBLE CAUSE SOLUTION
What do I do if the hood is working but pulling air slower than normal? Check
your baffle filters for buildup and clean or replace them if needed. If the

problem persists, check for obstructions in your ductwork. A common obstruction is buildup in the roof or wall cap, such as bird nests, leaves, or other debris.
My range hood will not operate.| Check that there is power to the range hood.| The most common issue is that the circuit breaker is off or the fuse has blown.
Make sure the speed has been selected at the range hood controls.
Turn off the power to the range hood and check that all wires are properly connected. Refer to your specific model’s installation instructions for proper wiring.
My hood is making a rattling noise.| The motor is loose.| Turn off the power and remove the filter and check that all screws are secure and tight around the motor.
The ductwork connection is loose.| Turn off the power to the unit and check that the ductwork connection to the pipe is tight. Add duct tape if necessary.
ISSUE| POSSIBLE CAUSE / SOLUTION
---|---
My range hood does not have power.| Check electrical connections. Check that all connections to the circuit board are secure. If the problem still exists, please call our customer service line.
Noisy Motor| Were the fan speeds checked fan speeds before installation? Is the ducting clear?

Check to make sure the motor is attached to the housing.

Is the backdraft damper on the transition piece functioning properly? Does it open when the hood is engaged?

If it is stuck, it will sound like motor noise but it’s the damper.

Was a damper installed on the roof or side vent?

Check that the damper is fully functioning by engaging the hood and checking if it opens and closes properly.

If the motor is accessible, the motor knob can be tightened.

ISSUE POSSIBLE CAUSE / SOLUTION
My range hood is not pulling. Was the unit plugged in and was the fan checked

before installation?

What distance is the hood mounted above the cooktop? Make sure the distance is 30″–36″/762–914 mm (indoor) or 36″–42″/914–1067 mm (outdoor).

Is the range hood width the correct size for the cooktop? Outdoor units should be at least 1 size larger if not 2.

Does the hood have enough BTU output about either their gas or electric stove cooktop?

Does the hood have enough BTU output about either their gas or electric stove cooktop?

Remember — BTU output per burner/100 – for gas, and wattage output per burner/10 – for electric.

Are the baffle filters or mesh filters installed correctly? When were they last cleaned?

Is the ducting clear?

Is the damper opening properly once the hood is turned on? Is there air coming out of the upper chimney section?

When tissue is placed on the baffle filters under the hood, does it hold the tissue?

How many elbows and how long is the ducting run?

There should be no more than 2–3 elbows and no more than a 40′ (12192 mm) run to exit — for every elbow subtract 5′ (1524 mm).

Is the air recirculating? When were the carbon filters last changed? The carbon filters need to be changed every 3–6 months based on your cooking habits.

    • ZLINE warranties apply only to the original purchaser of a ZLINE product installed for normal residential use. This is defined as a single-family, residential dwelling in a non-commercial setting. Any warranty claim stemming from installation, operation, or any other use within a commercial setting is not covered under this limited warranty. Commercial settings include, but are not limited to: schools, churches, hotels, restaurants, vacation rentals such as Airbnb, daycare centers, private clubs, fire stations, common areas in multi-family dwellings, nursing homes, food service locations, and institutional food service locations such as hospitals or correctional facilities.
    • This warranty is non-transferable and will not under any circumstance be extended based on the date of installation — the warranty period takes effect from the date of purchase and only covers the original purchaser. The warranty applies only to products installed in the contiguous United States and the District of Columbia.
    • Out-of-pocket payments will not be reimbursed for replacement parts unless prior approval is received from ZLINE. Unapproved out-of-pocket payments for parts will not be reimbursed.
    • Out-of-pockets for any type of service will not be reimbursed, as ZLINE does not perform service repairs on its range hood products. All warranty procedures must be followed to maintain warranty coverage.
    • If ZLINE is unable to replace the defective part after a reasonable number of attempts, ZLINE reserves the right to offer to replace the product or provide the original purchaser a full refund of the purchase price of the product (not including installation, removal, or other charges that were not included in the original purchase price).
    • The original purchaser of the product must provide the original proof of purchase, including the purchase date, when filing a claim to obtain replacement parts or refunds. Additionally, the original purchaser of the product must provide the serial number of the product when filing a claim to obtain replacement parts or refunds.
    • This warranty shall not apply to any ZLINE product in which the original factory serial number has been removed, altered, or cannot be readily determined for any reason. Further, ZLINE is not responsible for damage resulting from, but not limited to: shipment, delivery, or improper installation; negligence or improper maintenance, misuse, or abuse of the product; unauthorized alteration, modification, or tampering with the product; accident, fire, floods, pest infestations, pandemics, natural disasters, or any other unpreventable or unexplained acts of nature, commonly referred to as “acts of God”; flare-up fires or damages caused by improper electric supply, electrical line current, voltage, or power surges; and service to correct installation not by the instructions contained in ZLINE’s product manuals and/or with local government codes.
    • Additionally, this range hood warranty does not apply to aesthetic damage, scratches, or natural wear caused by normal use; second-hand, open box products, or products purchased from an unauthorized retailer; consumable parts including, but not limited to, metal and charcoal filters; and damages, problems, or any type of performance-related issues stemming from alteration or tampering with the range hood, including, but not limited to, painting stainless steel, black stainless, DuraSnow®, or designer- or wood-finished range hoods, and cutting the 3-prong plug to manually hardwire the hood.
    • Information contained within ZLINE’s installation and user manuals, in addition to product information included on ZLINE’s website and all related digital listings, do not cover every possible condition and situation that may occur during the installation or operation of ZLINE products.
    • ZLINE reserves the right to make changes at any time to its products when considered safe, necessary, and useful. Always check the ZLINE website for the most up-to-date version of its product manuals: www.zlinekitchen.com/pages/manuals.
    • Do not install or operate any ZLINE product if it has missing or broken parts or if it arrives damaged due to shipping. If ZLINE products arrive damaged, contact ZLINE Customer
    • Experience at 1-614-777-5004 for help. Failure to report a damaged appliance before installation or operation may void the warranty. ZLINE does not perform service repairs on its range of hood products.
    • ZLINE disclaims responsibility for damage or injury caused by improper installation or use of any of its products. ZLINE is under no obligation, by law or otherwise, to provide concessions, including repairs, prorates, rebates, discounts, or replacements, once the warranty has expired.

SERIAL NUMBER LOCATION

  • The rating tag shows the model and serial number of your range hood.
  • Please write down the model number and serial number of your appliance.
  • The serial number is located behind the baffle filters near the motor.
  • Both are needed to obtain warranty service. Do not remove permanently affixed labels, warnings, or plates from the product.
