Q: Is the range hood width the actual measurement that is advertised?

No. They are between a 1/8" and 1/4" smaller than listed, so that they fit properly into an opening of that nominal size.



Q: What's the best way to attach the range hood to the wall, and where is the best place to cut the 6" opening and install the 120v plug?

Range hoods are very heavy and must be well-fastened to the wall studs. Do not hang a range hood on the drywall or plaster alone. Use the stud locator to find the studs and make marks for the screws. Use the drill bit (smaller than the screw shaft) and pre-drill the screw holes. Don't use a drill bit that is too large; this could cause the range hood to pull away from the wall and this could result in injury.



Q: What's the best way to clean the surface of my range hood?

Stainless steel range hoods should be washed regularly with a clean cloth, warm water and a mild soap or dish detergent. Clean in the direction of the polish lines. Rinse well with clear water, and wipe dry immediately. You may wish to apply light oil used for furniture polishing to emphasize the range hood’s bright finish.



Q: How often should I clean my aluminum mesh filters?

The aluminum mesh grease filters should be washed in your dishwasher approximately every month, depending on the amount of usage. However, some dishwashers have increased pressure, so hand washing is recommended.



Q: Which is better, ducted or non-ducted?

Ducted range hoods are more effective at ventilating the air in the kitchen.



Q: What is the difference between internal and external blowers?

Internal range hood blowers are integral to the range hood itself - they are not in the duct work or on the outside of the building like external range hood blowers. (Remote range hood blowers may be located in the duct work or outside of the building.) Typically, externally mounted exhaust hood blowers are the most silent and efficient - it is a lot easier to pull the air than push it. It is also a lot easier to work on an external blower than an inline blower in the ceiling or soffit for example. The other critical component is ducting - if your ducting has restrictions in it due to many bends or crimping of the pipe, the blower will have to work harder and will be noisy. Internal blowers are less expensive than external systems; however, they are noisier because the motor is located inside of the hood.



Q: How far can I run my ductwork to exhaust my hood?

For maximum performance, keep the duct straight and short. Use the shortest route with the fewest turns possible. 45° turns are better than 90° turns. Be sure to use an external roof or wall cap. If in doubt, consult a qualified designer/installer who is knowledgeable in ventilation or contact us.



Q: Can I run the ductwork downward?

No portion of the ducting should be run so that the exhaust air flows downward. Since exhaust heat rises, forcing the air to flow downward will cause increased static pressure. Improperly installed duct pipe will cause excessive static pressure (air resistance) that may result in rattling, vibration and air buffeting noises, as well as inadequate ventilation.



Q: What height do I need?

Determining the proper height for your range hood can be simple as long as you know the height of your ceiling. The Spagna Vetro, Cavaliere and Cavaliere-Euro cannot be used for any applications under an 8 feet ceiling height.



Q: What width do I need?

The ideal width of your range hood should be six inches wider than your cooking surface (overhanging by three inches on either side). Having the range hood wider than the range allows for additional capture area, which allows for more efficient ventilation. Where space is restricted, the hood should be no less than the width of the cooking surface. Island units are a bit less forgiving than wall mounted units, and they require the additional 6 inches of capture area due to drafts within the room. Abiding by these recommendations will ensure optimal performance from your range hood.



Q: What depth do I need?

The depth of your range hood should ideally cover the cooking surface of your range from front to back. Our regular hoods are usually 20"; standard PROFESSIONAL wall vent models range from 24 to 27 inches deep, depending on cooking surface requirements, while our island models are a standard 27 inches depth.



Q: What style should I buy?

Choosing the right range hood can be like selecting the right outfit; it’s a matter of personal preference and style. Your kitchen ventilation range hood will likely be one of the focal points in your kitchen, making it one of the important design elements. When deciding on a design, take several things into consideration, including whether the rest of your home is traditional, contemporary or even rustic. The best shape for the hood’s performance is the pyramid shape hood, as it helps with the suction.



Q: Can I exhaust my range hood into my attic instead of out the roof or wall?

No. You should never exhaust air into spaces within walls, ceilings, attics, crawl spaces or garages. The humidity and grease collect in the space and present a huge fire danger. This is especially important and it is why we strongly recommend you have a professional installer do this type of installation.



Q: What does the CFM ratings mean?

CFM stands for Cubic Feet per Minute.



Q: How much CFM do I need for my range or cook top?

For conventional electric and gas ranges or cook tops, we offer a complete line of range hoods that can fit your cooking needs with the features you desire. For high output gas ranges or cook tops, the minimum rate of 1 CFM of ventilation per 100 BTU is recommended.



Q: How high should I mount my range hood above my stove?

Most installations require a range of 24"-32" between the bottom of the range hood and the top of the cook top. This will provide the best capture area for cooking impurities. For high capacity blowers, the distance from the cooking surface to the bottom of the hood should be a minimum of 24" for electric (induction) cook tops, and a minimum of 30" for gas cook tops, unless otherwise noted for a specific hood or range. The mounted height of the range hood base above the cooking surface should not exceed 31" for both wall-mount and island-mount units. The recommended minimum for Spagna Vetro168 and 218 series is 28" above the cooking surface. The hood should be centered over the cooking surface. This will provide the best capture area for cooking impurities. Consult your local building codes and standards for more information.

Q: May I remove the range hood controls and mount them remotely from the hood?

Altering the product voids manufacturer's warranty and certification.



Q: Please give me more information on charcoal filters (filtration version only).

Charcoal filters are neither washable nor renewable. They are used to catch unpleasant smells that develop during cooking. They should be mounted on the safety grille of the motor and replaced every 4 months.



Q: Some building inspectors require "Makeup air" for hoods over 500 CFM. What is "Makeup air"?

When a range hood operates, it draws air from inside the house to the outside and creates or contributes to a slight vacuum in the house. The resulting negative pressure can be serious. If the negative pressure is strong enough, it can cause the furnace and other fuel-burning appliances to back-draft dangerous gases, such as CO, into the home. All exhaust fans, including clothes dryers, must have an adequate supply of air. The air needed for this purpose is called makeup air. Although make up systems are not mandatory in all regions, some regions have created legislation to ensure make up air systems are installed, and it is important for homeowners to consult with local building codes. The installation of a ducted range hood allows air to be changed efficiently, which improves the quality of the environment in which you live. Even if a makeup air system is not required or mandatory in a specific application, simply opening a window to the exterior can effectively assist in this process. This is something to consider in many of today air tight homes. Please check with your building inspector to determine whether or not you need a makeup air unit.



Q: What is stainless steel?

Stainless steel is the material used in manufacturing 90% of our products. All stainless steels contain iron and a minimum of 10.5% chromium oxide ("CrO") (other elements used to make stainless steel include nickel, nitrogen and molybdenum). The chromium in the steel is combined with oxygen to form a thin, invisible layer of chrome-containing oxide. This layer is only a few atoms thick due partially to the ability of the chromium atoms and oxide atoms to pack together tightly. This layer protects the steel underneath and has a unique self-healing ability. Should the layer become scratched or cut, the newly exposed steel will form another protective area with oxygen in the air .Stainless steel is a corrosion resistant (rust resistant) metal; it is easy to sanitize and clean. It actually isn’t stain resistant, but it stains less than other types of steel. It is also an earth friendly material; it can be melted down, recycled and made into something else. Stainless steel is 100% recyclable. In fact, over 50% of new stainless steel is made from melted scrap metal, rendering it an eco-friendly material. It is important when purchasing any item that claims to be made of stainless steel to ask if the steel is completely stainless or if it is just top-level plating with a cheaper steel or metal underneath. All our products are made of 100% stainless steel material.



Q: What are the types of stainless steel?

A commonly used grade of stainless steel for range hoods and sinks is Type 430 (S43000).The basic alloy contains 11% chromium and 1% manganese.

Grade 304 is the most common grade of stainless steel used in our industry. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon.

Grade 200 stainless steel alloy contains 17% chromium, 4% nickel and 7% manganese.



Q: What are the gauges of stainless steel?

Gauge (or gage) sizes are numbers that indicate the thickness of a piece of sheet metal, with a higher number referring to a thinner sheet. The equivalent thicknesses differ for each gauge size standard, which were developed based on the weight of the sheet for a given material.
