SELECTING A VENTILATION SYSTEM Selecting a Ventilation System When selecting a ventilation system, start by choosing the proper Wolf ventilation product, determined by the type of cooking appliance used and the following considerations: IMPORTANT NOTE: Wolf cooking products do not require ventilation when installed according to the installation instructions. Recommendations and suggestions in this guide are for performance only.
SELECTING A VENTILATION SYSTEM Selecting a Ventilation System Wolf pro ventilation hoods and liners can be used with all cooking appliances, including ranges and rangetops. A downdraft system can also be used with sealed burner rangetop models SRT304 and SRT366. An accessory trim kit is required for this installation and is available through an authorized Wolf dealer. For local dealer information, visit the find a showroom section of our website, wolfappliance.com.
SELECTING A VENTILATION SYSTEM Selecting a Ventilation System UPDRAFT OR DOWNDRAFT HOOD MOUNTING HEIGHT The choice between updraft ventilation and downdraft ventilation will depend on several factors, most notably the cooking appliance, type of installation and location. Updraft ventilation, or an overhead hood, is typically a more effective ventilation option. Cooking vapors naturally rise, making it easier to collect and remove them from the cooking area. Proper mounting height is very important.
SELECTING A VENTILATION SYSTEM Selecting a Ventilation System COOKING SPACE / COOKING STYLE INTERNAL, IN-LINE OR REMOTE BLOWER The appropriate airflow capacity is determined by the cooking space and cooking style. If the cooking surface is in an island or peninsula, a higher airflow capacity hood can provide better capture for cross currents, or if the hood needs to be mounted higher. Downdraft ventilation may also be an option. All Wolf ventilation products are shipped without the blower assembly.
SELECTING A VENTILATION SYSTEM Selecting a Ventilation System DUCTING CONSIDERATIONS ELECTRICAL REQUIREMENTS IMPORTANT NOTE: Unless used in a recirculating application, Wolf ventilation hoods and downdrafts must be vented to the outside. Use only rigid metal ducting. All Wolf ventilation products require a separate, grounded electrical supply. Installation must comply with all applicable electrical codes.
SELECTING A VENTILATION SYSTEM Selecting a Ventilation System Ventilation Made Easy RECIRCULATING VENTILATION After choosing the proper ventilation hood or downdraft, follow this three-step process to determine your blower needs to complete the ventilation system: Recirculating ventilation units are installed on top of a ventilation hood with no ducting required. Recirculating units recycle the air through a charcoal filter and return it to the kitchen.
DETERMINE THE DUCT RUN Step 1: Determine the Duct Run IMPORTANT NOTE: Consult a qualified HVAC professional for specific installation and ducting applications. Check local codes. | Consult a qualified HVAC professional to ensure all applicable codes are followed. Refer to the installation guide for your specific Wolf ventilation product. Minimize the duct run. | The length of the duct run and number of elbows and transitions can have a significant effect on ventilation performance.
DETERMINE THE DUCT RUN Step 1: Determine the Duct Run Equivalent duct length. | Determine the equivalent length of the duct run using the equivalent duct lengths for commonly used ducting listed below. Follow these steps and use the chart to calculate the equivalent duct length: 1 Compute the length of all straight ducting. 2 Compute the equivalent duct length of all elbows, transitions and caps. 3 Add equivalent lengths for all sections of the duct run.
DETERMINE THE CFM Step 2: Determine the CFM Step 3: Select a Blower Ventilation performance is measured in cubic feet per minute, or CFM. The chart below provides CFM recommendations specific to the Wolf cooking appliance and ventilation system used. To maximize airflow and performance, specify a blower to match or exceed the CFM listed. All Wolf ventilation products are shipped without the blower assembly.
